SOURCE FINDER EXCEL SPREADSHEET
I've been making this table that is specially created for ROM Developers, at first I was doing it for my own knowledge in the rom structure, but why not share? It's not even 50% done (only app/framework so far) but it's worth sharing I think. I will continue to fill in the empty spaces along my building experiences. applying content (more info for table) is greatly appreciated as we all benefit from this table.
Typical scenario where this comes handy: (over dramatized in favor of this spreadsheet)
You're trying to port a rom to your phone, (from source) and you keep getting errors, of course you have logcat as your pet, but still you cannot figure out where to search for that specific thing that keeps crashing, and not to mention in ALL THOSE FOLDER AND FILES (a compiled repo takes upto a [/B]half million[/b] files), of course your developer instincts tell you to do a recursive search but you will find the same folder 20 times, then you think of a recursive grep, but also that returns a ****load of useless info (all links). then you sigh... and take the excel spreadsheet, you lookup the file and browse directly to the right folder, including you know what dependencies it has, so backtracing is easily possible. from here it's smooth sailin' :silly::silly::silly:
Idea's for the "future":
- expand table with binaries from /system/bin, and possibly more folders (after completing libraries)
- make shell script that jumps to the source dir by entering the module/apk/jar name (for example "go services.jar" should jump to frameworks/base/services)
- using "clean services.jar" would delete services_intermediates and it's dependency intermediates. (implemented qc into envsetup.sh, a quick rm -Rf of the chosen intermediates, about 100 times as fast as 'make clean-services for example)

Hi, I'm trying to build CM KitKat for the Optimus S/V (unsupported by CM). The build is crashing out trying to link libwebviewchromium.so.
It gives dozens and dozens of errors like this:
external/chromium_org/content/browser/android/browser_media_player_manager.cc:70: error: relocation overflow in R_ARM_THM_CALL
At the end it prints this:
collect2: error: ld returned 1 exit status
make: *** [/home/dbrown/cm11/out/target/product/thunderc/obj/SHARED_LIBRARIES/libwebviewchromium_intermediates/LINKED/libwebviewchromium.so] Error 1
It may be a problem with insufficient memory on my build machine (Core 2 Duo laptop with 3 gb ram). For the time being, or in case that's not the problem I'm looking for a work-around. I looked in the Android.mk file for external/chromium_org and saw this:
# Don't include anything if the product is using a prebuilt webviewchromium.
ifneq ($(PRODUCT_PREBUILT_WEBVIEWCHROMIUM),yes)
Is it possible, and if so how can I add a prebuilt webview library so I can get past this error? I just want to get something built for now so I can test it. This would be the first successful build for this device. Thanks!
Open the "external/chromium_org/content/browser/android/browser_media_player_manager.cc"
And go to line Num. 70..
Youd better to see "https://bugs.launchpad.net/binutils-linaro/+bug/641126"
In that case, Loïc Minier was solve the add physical ram.
To try swap memory!
I know this is a bit necro but I thought I'd add.
I got the same error in libchromium. 16Gb ram. Went down to -j1 on make and it compiled. I have a 6-core chip :/
Similar query
For doing the android clean build faster I wanted to avoid building libwebviewchromium. Can someone provide the exact changes needed for this. Is libwebviewchromium.so enough ? or do we have to have related jars as well from first build.
@skinbark @winvinay add the following line to your devices BoardConfig.mk. (I.e. YOURSOURCEFOLDER/device/MANUFACTURER/DEVICE/BoardConfig.mk e.g. ~/AOSP/device/asus/grouper/BoardConfig.mk for me):
Code:
PRODUCT_PREBUILT_WEBVIEWCHROMIUM := yes
Just remember to add libwebviewchromiun.so from another ROM to /system/lib/ afterwards.
I have been having issues with the Paranoid Networking feature added to the Linux Kernel preventing some of my programs from creating sockets.
Appearently the process must be of a certain group id, either one of the AID_INET or AID_BT groups in the 3000's range I believe. I was cgreping through the source code and it seems a few calls to "in_egroup_p(gid_t)" are made to test if the process's group is 'correct' when ANDROID_PARANOID_NETWORKING is defined. If I understood the "in_egroup_p()" function, it should return 1 (retval) if there is a match. so what I did was this in the c file for inet in the kernel. I hope the kernel gets compiled, I just did a "make clean" and "brunch d2spr" it is cm-10.1
Code:
#ifdef ANDROID_PARANOID_NETWORKING // this was there
if ( in_egroup_p(0) == 1) {
return 1;
} // I added this
return in_egroup_p(AID_INET) || capable(I_FORGOT_HERE); //this was there
And I am hoping that when I execute the program as root, it will have permission to create a socket. Also note, that the programs I am having problems for are glibc based that I copied and mounted from a .img file. Programs such as postresql, gdm3, and others. It is a debian distro that I mount with an init service when a property is set to 1.
If this does not work, I will need to run without the Paranoid Networking patch to the kernel. What config file do I need to edit so that ANDROID_PARANOID_NETWORKING does not get defined or built into the kernel?
edit: I feel like this, " IM ROOT B****, STAY OUTTA MY WAY! " And then that scene from Jurrasic Park comes to mind

Still no go
Code:
[email protected]:/etc/init.d# ./postgresql start

failed!
*BEEP* *BEEP* *BEEEEEEEEEEP*
Hmmm... Maybe the kernel didn't compile? I dunno . ...
Where is the config file for the kernel that comes with CM-10.1 so I can turn off this paranoid networking?
My philosophy is that they shouldn't be there to start a socket in the first place, but if I want to, I should be able to. This is where I need something akin to sudo, but as root this is pissing me off, let me create a socket por favor!
I tried a lot of things but this just isn't working right. Some one please, help.
I've about had it up to my neck with Android. ****ing bull ****, I didn't know I was buying a bad ass phone with Chains and Iron Bars for an OS. FREEEEEEEDOOOOOOMMMMMNNNNNNNNN
After breaking my build, I deleted my kernel directory tree and re-sync'ed. I then did "source build/envsetup.sh" and "breakfast d2spr" and then I when to "kernel/samsung/d2/" and did "make menuconfig" then I unselected in networking options "Only specific groups can create sockets" or some such option. and then "brunch d2spr". We shall see if that works.
Update:
Did not work. Said unfinished jobs yada yada
So what I am trying now.
I cleaned everything, bummer!
I copied my kernel dir to another location
I pulled my kernel config with adb
I used that with 'make menuconfig' and edited out the 'only allow certain groups' bit
I saved that
copied it to my source in kernel/samsung/d2/
I edited AndroidKernel.mk to use that config file instead ( the assignment occurs at the top of the file)
croot
brunch d2spr
waiting till tomorrow more than likely....
Update: ( 3 hours later )
Its taking long enough
seems to be working
maybe I can make a config in my source tree and then make mroper and clean, aswell as in the KERNEL_OBJ dir in out/*, then brunch. to avoid needing two kernel source trees and some confusion in case I modify any of the source and not just the config.
AndroidKernel.mk specifies which config file to use instead of the other pre-configured files, just start by pulling a config off your phone with the same rom and device your building for.
Code:
adb pull /proc/config.gz
That will pull the conpressed file off your phone to the current working directory, then gunzip it. Then launch
Code:
make menuconfig
from your kernels root dir, for me that is "/home/$USER/android/system/kernel/samsung/d2/"
And then once the menu is up, use the arrows to scroll down to the bottom and use enter or return to select the option to use a different configuration file, it should change menus to one with ".config" erase that and change it to point to your config file, I just copied mine to the same directory mentioned above with the name "config" the same without the "." (dot/period) in front.
After that, from the same dir ( as well as in the KERNEL_OBJ/ dir somewhere within the out/ dir)
Code:
make mrproper && make clean
to clean the previous kernel make.
After all of that, you can 'croot' and 'brunch $YOUR_MODEL', but not before making sure you change which config file to use in your kernel's root dir in it's AndroidKernel.mk file. Its at the top, I used an absolute path for my installation, just in case.

Hi, good start. In fact I have, the differences in the kernel options between C6833 and C6843 (Brazilian model with digital TV) are:
Code:
47c47
< CONFIG_MACH_SONY_TOGARI_BRAZIL=y
---
> CONFIG_MACH_SONY_TOGARI_ROW=y
275d274
< CONFIG_ISDBT_TUNER_SMTEJ11X=y
325a325,327
> CONFIG_TOUCHSCREEN_CLEARPAD=y
> CONFIG_TOUCHSCREEN_CLEARPAD_I2C=y
> CONFIG_TOUCHSCREEN_CLEARPAD_RMI_DEV=y
Yes, I don't know why the Clearpad touchscreen is enabled for the C6833, but not for the C6843; I think it's just garbage (perhaps they made the togari defconfig based off honami, and corrected that when making the togari_brazil defconfig). It doesn't make any difference for me, disabling them keep the touchscreen (MAX1187) functions normal.
Well, back to the point: even when applying these differences to the ZU DooMKernel, the digital TV doesn't work. The app stays a long time in a black screen, and finally closes (FC). I investigated the kmsg and logcat, but nothing useful.
CONFIG_DVB_CORE is "m" by default. I tried insmod'ing every module in /system/lib/modules, but same result. I temporarily gave up, because I don't watch the crap they broadcast on the open TV here. But yeah, it would be good to have everything working...

I hadn't got around to diff'ing them I just noticed the DVB line and had a quick look at the brazil defconfig.
I guess there is a binary blob that is needed?
For some reason I have to include the clearpad stuff at the moment in the pimped kernel, I should dig to find out why so the kernel is a tad smaller.

Hmm very good insight about the binary blob... It's very possible. I have FTFs for the C6833 and C6843, I'll extract them and compare the file list.
I made it work!! Well, involves some manual steps, but it's a very good progress. I started by comparing the file listing in /system from stock C6833 and C6843 firmwares, and although there is no kernel blob, there ARE some files related to DTV, mostly dynamic libs (.so), some configuration, but most importantly, these two:
Code:
/system/bin/dtvsdserver
/system/bin/dtvserver
So, I insmod'ed every module related to DTV/DVB, and then started these guys... And the TV works! BUT, as soon as I quit the Mobile TV app, the process "dtvserver" is killed with a hangup signal, and opening the app again does not restart it, so I have to manually bring the dtvserver up first (otherwise the same previous issue happens, black screen and finally Mobile TV FC's).
I notice some DTV/DVB modules couldn't be insmod'ed:
Code:
insmod: init_module 'dib3000mc.ko' failed (No such file or directory)
insmod: init_module 'dib7000m.ko' failed (No such file or directory)
insmod: init_module 'dib7000p.ko' failed (No such file or directory)
insmod: init_module 'dib8000.ko' failed (No such file or directory)
insmod: init_module 'dib9000.ko' failed (No such file or directory)
insmod: init_module 'mpq-dmx-hw-plugin.ko' failed (No such file or directory)
insmod: init_module 'tuner-simple.ko' failed (No such file or directory)
But the modules are there, and they are the new ones... I don't get it why they can't be insmod'ed, perhaps something is missing from the kernel config? It could be one of the reasons.
Another thing I've been wondering, is why the DVB modules necessary for the Mobile TV are not loaded automatically, like the wlan module is, for instance. Perhaps a difference in the ramdisk? Something to investigate next.

Congrats on getting that far with the DTV, will make for a more complete device for the c6843 users that want to use custom ROMs
Any differences in udev or init.rc or whatever android uses?
Development using the GPL and GPL'd code
The GPL is a very powerful tool, as are the other OSS licences. One has to know how they are used and can/can't be enforced before publishing any code under these licences or modifying code that that been published under a OSS licence. Using a OSS licence brings with it risks and rewords, often these are one and the same.
When we do anything with Android [Linux] kernels we fall under the bounds of the GPL v2 that it is published under. Any modification to the kernel has to be published under the same licence, and we have to publish the newly modified source in a sate that can recreate the binary that you publish to the public/xda.
I'll leave you with this quote from http://programmers.stackexchange.com
...are you prepared to live by it, and let other people use what you've written, rather than just liking it because of what you can get out of it?

F2FS mount and sysfs options
Now that we have an F2FS-enabled firmware by default, I've been reading about the mount options and sysfs entries available. As many of us know, there are lots of tweaks out there for EXT4, but what about F2FS? Well, here is the official documentation from the Linux kernel:
https://www.kernel.org/doc/Documentation/filesystems/f2fs.txt
As for the mount options, I think only discard could be interesting (but it's questionable, some people say it's better to schedule a regular fstrim call instead). There are also some sysfs tunables which I think can have a noticeable impact in battery life, and performance. Testing them would require a lot of trial and error. I'm pasting them below for those who don't want to go through the full document:
Code:
================================================================================
SYSFS ENTRIES
================================================================================
Information about mounted f2f2 file systems can be found in
/sys/fs/f2fs. Each mounted filesystem will have a directory in
/sys/fs/f2fs based on its device name (i.e., /sys/fs/f2fs/sda).
The files in each per-device directory are shown in table below.
Files in /sys/fs/f2fs/<devname>
(see also Documentation/ABI/testing/sysfs-fs-f2fs)
..............................................................................
File Content
gc_max_sleep_time This tuning parameter controls the maximum sleep
time for the garbage collection thread. Time is
in milliseconds.
gc_min_sleep_time This tuning parameter controls the minimum sleep
time for the garbage collection thread. Time is
in milliseconds.
gc_no_gc_sleep_time This tuning parameter controls the default sleep
time for the garbage collection thread. Time is
in milliseconds.
gc_idle This parameter controls the selection of victim
policy for garbage collection. Setting gc_idle = 0
(default) will disable this option. Setting
gc_idle = 1 will select the Cost Benefit approach
& setting gc_idle = 2 will select the greedy aproach.
reclaim_segments This parameter controls the number of prefree
segments to be reclaimed. If the number of prefree
segments is larger than the number of segments
in the proportion to the percentage over total
volume size, f2fs tries to conduct checkpoint to
reclaim the prefree segments to free segments.
By default, 5% over total # of segments.
max_small_discards This parameter controls the number of discard
commands that consist small blocks less than 2MB.
The candidates to be discarded are cached until
checkpoint is triggered, and issued during the
checkpoint. By default, it is disabled with 0.
ipu_policy This parameter controls the policy of in-place
updates in f2fs. There are five policies:
0: F2FS_IPU_FORCE, 1: F2FS_IPU_SSR,
2: F2FS_IPU_UTIL, 3: F2FS_IPU_SSR_UTIL,
4: F2FS_IPU_DISABLE.
min_ipu_util This parameter controls the threshold to trigger
in-place-updates. The number indicates percentage
of the filesystem utilization, and used by
F2FS_IPU_UTIL and F2FS_IPU_SSR_UTIL policies.
max_victim_search This parameter controls the number of trials to
find a victim segment when conducting SSR and
cleaning operations. The default value is 4096
which covers 8GB block address range.
dir_level This parameter controls the directory level to
support large directory. If a directory has a
number of files, it can reduce the file lookup
latency by increasing this dir_level value.
Otherwise, it needs to decrease this value to
reduce the space overhead. The default value is 0.
ram_thresh This parameter controls the memory footprint used
by free nids and cached nat entries. By default,
10 is set, which indicates 10 MB / 1 GB RAM.
@blueether & @dbolivar :

I'm giving it a try - downloaded the latest sources from CodeAurora and applied to your kernel (adjusting Kconfigs, Makefiles and defconfig). The compilation stops here:
Code:
drivers/staging/prima/CORE/HDD/src/wlan_hdd_cfg80211.c: In function ‘wlan_hdd_send_avoid_freq_event’:
drivers/staging/prima/CORE/HDD/src/wlan_hdd_cfg80211.c:574:18: warning: assignment makes pointer from integer without a cast
error, forbidden warning: wlan_hdd_cfg80211.c:574
make[3]: *** [drivers/staging/prima/CORE/HDD/src/wlan_hdd_cfg80211.o] Error 1
OK, so I edited wlan_hdd_cfg80211.c and changed line 574 to add an explicit cast:
Code:
vendor_event = (struct sk_buff *)cfg80211_vendor_event_alloc(pHddCtx->wiphy,
Then it passes by this point, but stops in following lines with similar errors (not even pasting here). What I noticed from these errors it that CodeAurora's sources seem to be incompatible with Sony's kernel, because for instance, the function cfg80211_vendor_event_alloc is not defined anywhere (ran a grep over all *.c and *.h files in the kernel).
Comparing with a CM11 kernel, this function is also not defined anywhere, but the prima sources are very different, they don't call it. So I thought: let's use CM11's prima sources.
Bingo!
Compiled fine, booted, and with the correspoding firmware in /system/etc/firmware/wlan/prima, WLAN came up normally after boot. :victory:
Now you mentioned something about CM11's prima sources, from what I understood they are not ideal. Is that true? Because there are CM11-based custom kernels which implement intelliplug (dependent on custom WLAN drivers), for instance.
Hope it works for you. In this case, I'll put together a more organized how-to of what I did.

great!
can you just fork my repo and shift to the branch which worked for you, then send pull request? i will investigate on the Z1...
and yes please do send the steps!
well if we get custom compiled WLAN modules properly working on custom compiled kernel for stock ROM then i can have features like intelli-plug, F2FS, AsyncFS and lots more on stock ROMs!

Well I'm still learning my way around git & GitHub, so I think it will be faster if you just reproduce the steps below:
1) Copy Prima WLAN sources from CM11-based kernel:
I copied from SlimRom's kernel source. Put the sources under drivers/staging/prima.
2) Modify related Kconfig and Makefile:
drivers/staging/Kconfig
Code:
131,132d130
< source "drivers/staging/prima/Kconfig"
<
drivers/staging/Makefile
Code:
58,59d57
< obj-$(CONFIG_PRIMA_WLAN) += prima/
< obj-$(CONFIG_PRONTO_WLAN) += prima/
3) Modify defconfig:
I'm pasting every option related to WLAN. The Prima options should appear after a "make menuconfig".

Actually I include every compiled kernel module, because we are using a different toolchain and they may benefit from it too. Remember that /system/lib/module/wlan.ko is a symlink, but in my test the target got updated accordingly.

Well I'm still learning my way around git & GitHub, so I think it will be faster if you just reproduce the steps below:
1) Copy Prima WLAN sources from CM11-based kernel:
I copied from SlimRom's kernel source. Put the sources under drivers/staging/prima.
2) Modify related Kconfig and Makefile:

The branch from your kernel was master_kk-4.4.2. The Prima WLAN sources were, as I mentioned, from SlimRom's kernel, branch kk4.4.

Wow this is very nice! Follows the same line of research I've been doing, but this is more "elegant" and in-depth, especially because of all the benchmarks and other comparisons he has done. I'll try this approach myself on my custom builds.
One thing I noticed is that we may still have to use the "hammer" approach with the find & replace of the "-O" flags in *.mk and Makefiles I've been doing, because some of them have these flags hardcoded (i.e. they don't take the value from core/combo/TARGET_linux-arm.mk or other base files). I'll tip JustArchi in his thread about it.
Hi guys, I posted this in the general android section and have had no answer, maybe some one here might know?
I'm trying to build AOSP using CM 11's device tree for togari/togari_gpe and have hit a brick wall after solving the first few make errors.
I have to errors, that I suspect are the same problem:
The first is if I just build with make I get this error:
Code:

compilation terminated.
make: *** [out/target/product/togari/obj/SHARED_LIBRARIES/libqdutils_intermediates/mdp_version.o] Error 1
make: *** Waiting for unfinished jobs....
and if I do make bootimage I get this:
Code:
make: *** No rule to make target `out/target/product/togari/kernel', needed by `out/target/product/togari/boot.img'. Stop.
I suspect that both stem from aosp not finding the kernel source?
kernel source is at ~/dev/aosp/kernel/sony/msm8974/ and I'm building in ~/dev/aosp
I'm also trying to build vanir aosp using the same device tree and kernel and make bootimage completes fine.
Any help would be great
Yo, @DooMLoRD, @blueether @dbolivar
You guys have probably registred that Geohot (iPhone, PS3 jailbreaker) has successfully rooted the Galaxy S5 (and can now claim the $18,000 bounty), but i just read that this one-click root tool should work on any device running a pre-June 3rd kernel, i.e Android 4.4.2. The question is, does it work on the Ultra? I'm aware that it's easy to root an UItra AS LONG as the bootloader is unlocked, but this thing circumvents that part, and roots it. I think.
Are there anyone here still left on 4.4.2 that can try?

Little info on what this all is.
If you are expecting a working kernel or rom after reading this all. That is not what this thread is.
What this all is intended for is material to help with getting you to the next step, if you are at a road block.
What will you gain from all this?
A fair bit of knowledge on working with msm-4.14 kernel and maybe others.
Make sure to have your search bar ready with a piece of the issue (key word of the error will do) and go through the hidden tabs until you pick up your error, with the browser search function (ctrl+f on most browsers)
Spoiler: OLD info
Method I used for building the kernel
1. Dowload AOSP common-kernel-4.14 through git
OR
ANDROID 10 Specific
refs/heads/q-common-android-4.14 - kernel/manifest - Git at Google
2. Download Xiaomi TUCANA-Q-SOURCE for android 10 source code from MiCode git.
ALL VARIANTS

3. extract if you did not use git to download sources.
You will need AOSP 10 R29 downloaded. R29 Matches Stock MIUI 12.0.4
4. mkdir kernelbuild (can be what ever) then extract both AOSP KERNEL (git) ,build, common, kernel, prebuilts, master-prebuilts folders to the kernelbuild folder.
5. just use TUCANA source and don't merge with AOSP common source. Don't delete common either
4. copy AOSP kernel folder (contains 4.14) to TUCANA source and merge (Still not sure if you need to do this)
5. make sure you have AOSP-10 from git already. If not, repo it.
6. Go to AOSP-10 REPO>prebuilts>gcc>linux-x86>aarch64 location and get (aarch64-linux-android-4.9) folder and copy it to root Tucana source files folder make a directory call toolchain TUCANA source. in prebuilts>gcc>linux-x86>aarch64 folder replace and merge all
7. Not sure if this is outdated but got the export info from MSM section at https://github.com/MiCode/Xiaomi_Kernel_OpenSource/wiki/How-to-compile-kernel-standalone
e.g.
export CROSS_COMPILE=/<toolchain-location/prebuilts>GCC>/bin/aarch64-linux-android-
mkdir out
cd out
Taken from mi code section for MSM 4.14
export ARCH=arm64
export SUBARCH=arm64
export DTC_EXT=dtc
Set CONFIG_BUILD_ARM64_DT_OVERLAY=y
(does not work from what i can tell. Have to enable using menuconfig)
if not inside the "out" folder use O=out on next command, will also have to type cd ../ to go back in source if using this command.
(-jN (N is for a number))
make -jN tucana_user_defconfig
make menuconfig (configure config to your liking)
use save button (highlight save and press enter, can use arrow key right and left as well)
make -jN
Or it could be
make -jN ARCH=arm64
After doing all this, for me the build fails. Its driving me insane!
I think I also was using the wrong AOSP kernel, was using common-4.14 and now using this one
refs/heads/q-common-android-4.14 - kernel/manifest - Git at Google
guessing the Q is for Android 10
MY DEMON!!!!!
1615228944041.png
i think it is not working because i am using Android 10 R41 and should be using Android 10 R29. Testing it now.
Alright, went from ubuntu version 20 to 18 (Bionic is more reliable and easier to set up).
Had 20, due to bionic auto updated (my own fault).
Version 20 does work with some modding and adding bionic to the repo's of ubuntu.
I tried using AOSP toolchain and also Qualcomm's (QQ-LLV) LLV toolchain 8.0 for clang.
The part from MiCode wiki on github is saying to use CLANG_Triple with aarch64-linux-gnu which I can not find this file anywhere.
Not in QQ-LLV, AOSP-10-R29 aarch64 that is located in prebuilts > gcc
so the main problem I am getting is the cpu timer failing, during the build process. I try to modify the config by typing "make menuconfig" and then change the cpu govern type from performance to ondemand and saving it as .config (not sure if it is supposed to be the same name as the tucana-user-defconfig, let me know if this is the problem)
the AOSP android version I am using is R29. The AOSP kernel I am using is common-4.14
none of these files have aarch64-linux-gnu.
I am starting to slowly give up on this whole thing. spent 7 days just to get a cpu timer problem during build.
Oh and the source i am using is from Micode github under tucana for android 10 (Q)
Just sprung up an idea. I think i am supposed to first use Qualcomms LLVM toolchain 8.0 with the Mi source code package to make up the files needed in order to use anything from AOSP. please let me know if this is correct.
No matter what guide i find for it, it shows CLANG_TRIPLE=aarch64-linux-gnu- and every time. it just can not find it. no idea how to get this.
it work in clang triple for -gnu

Spoiler: UPDATE 2022 WORKING BUILD WITH ISSUES
Alright I decided to give it another shot in 2022 because of getting replies.
1. Get your source from device brand. (https://github.com/MiCode/Xiaomi_Kernel_OpenSource)
2. Use Mi code wiki to learn how to build (https://github.com/MiCode/Xiaomi_Kernel_OpenSource/wiki)
3. Go right hand side for standalone kernel. Because the how to section just waste hours on end with nothing built and Soong and clang errors.
4. Follow msm-4.14 for a guide. (https://github.com/MiCode/Xiaomi_Kernel_OpenSource/wiki/How-to-compile-kernel-standalone)
5. Make sure to have dtc binary file from aosp source (https://android.googlesource.com/platform/prebuilts/misc/) choose your android version. Check device for android version. Can use CPU ID in playstore under System, section API LEVEL.
6. Get llvm Snapdragon from Qualcomm. (https://developer.qualcomm.com/software/snapdragon-llvm-compiler-android) I used both but you should be able to use 8.0. both have off same results during the build process.
7. Get Aosp gcc
(https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/aarch64/aarch64-linux-android-4.9/)
8. Put LLVM Snapdragon toolchain and AOSP gcc into a folder in root of kernel folder called toolchain.
9. Run the script mi provided. Change the 6.0 on the last 2 make commands to 8.0 unless you are already using 6.0, then you can leave it at 6.0.
10. Build.
11. Get a boot.img extractor from github or on these forums. I can't recommend one yet, due to not having full success. Can search boot.img extractor or boot.img unpacked as seperate search terms.
**Recommendation**

Hey mate, thanks for the reply. Could you put a link to your thread so I can check it out.
Found it: https://forum.xda-developers.com/t/building-lineageos-17-1-from-source.4245417/
I also have posted on Qualcomm forums.
LINK: https://developer.qualcomm.com/forum/qdn-forums/software/snapdragon-llvm-compiler-android/68403
I found out qcomm has its own builder for msm devices. It's known as QAEP. I have been trying to build the sm6150 with Tucana defconfig. The thread above is the issue I have in trying to build it. No idea how to get "SDClang" so as soon as I work that out. It should build with QAEP instead of using AOSP.
There's a commit where I add SDCLANG support (but I don't think that's needed, is backed out atm) https://github.com/alibei/android_d...mmit/efbb3c66aa0d385e58052675402489c13392576e )There's a similar commit in the kernel.
You need to register to Qualcomm to download it, and unzip it in kernel/toolchains, just as https://github.com/MiCode/Xiaomi_Kernel_OpenSource/wiki/How-to-compile-kernel-standalone says under "You must get llvm clang from qcom". You just have to get the 8.x version.
Some snippets for the commands I've tried https://gist.github.com/b100dian/40c8dbe746ff181aff71ee10a75a5f3c

Yeah I am not trying to use Lineage sources. so far steps I have taken are as follows.
1. Mi source code download of Tucana android 10, data source, wifi source, audio source.
2. Extracted Mi tucana source in a directory (also tried the git way to update CAF tags).
3. using AOSP as the source for build. I tried using Clang with cross compile with gcc (GNU)
4. with using all AOSP toolchains so clang and gcc from AOSP and then using LLVM clang as reall cc, due to it does not contain clang itself.
all that for kernel and it builds but I feel its missing drivers. due to the warnings that Qcom gives. also got wifi modules installed but not audio. Audio source is a little different then the wifi source.
For the proprietary binaries. I used lineage Extract script with the lineage 17.1 tucana proprietary-files.txt list.
extraction worked on miui_TUCANAGlobal_V12.0.4.0.QFDMIXM_be49be8fa0_10.0.zip.
but of course the device tree is missing, found the platform sm6150 device tree on QAEP. so now trying to use QAEP to build not only the kernel but the rom as well using QAEP instead of AOSP. think we need to use QAEP, then using the files built. can then move over to aosp for upgrading, etc.
Could you explain this error considering you managed to get SDClang working. it may solve my problem. error provided below.
Spoiler: sdclang error
I have a SDCLANG_PATH set in BoardConfig.mk in the commit I pointed to earlier.
Basically is from a toolchains folder creaded with `tar -xvzf snapdragon-llvm-8.0.6-linux64.tar.gz` in the kernel/xiaomi/tucana folder

this has been added just above wifi. still fails with same error.

I think I just solved it, so i noticed you talk about Boardconfig.mk and when i checked out your git code, it had in the same config the target. well QAEP is a little different it not only has a Boardconfig file but also a AndroidBoard config file. so i think i am supposed to be adding it in there instead of Boardconfig. testing it now.

Something else i also noticed that is not working.

And can confirm above configuration changes are not working, not sure where it is located to tell it the path.
I cannot speak for QAEP (I barely began reading about lineage but in my case I don't have out/target/product/sm6150 at all, only out/target/product/tucana, which seems to be the name of the kernel (or device or vendor). Do you also have other repos pulled in that contain kernel named sm6150? Like https://github.com/LineageOS/android_kernel_xiaomi_sm6150 Maybe you should not have both

So where yours is out/target/product/tucana, the one for QAEP is SM6150 which is in the same location. so I think maybe on the right track here. also thanks for the help for llvm dragon, had to set bin path, for it to work. but i have not gone a built the rom yet, doing the kernel build first now.
Instead of relying on QAEP builder. I went and got kernel/build from code-aurora for android 10 r40 and ended up getting misc linux folder in kernel also gcc and build tools from the device tag release repo on codeaurora.
Usually i was using AOSP but now switched over to all QAEP tools and sources.
I am testing the Micode Audio and wifi source. got wifi working during kernel build by adding this below.
EXT_MODULES="
mods/wlan/qcacld-3.0
"
IN_KERNEL_MODULES=1
I believe that installs the wifi drivers for the device as a module. but building with clang, gcc and gnu as clang tripple this is all related to only kernel building.
Spoiler: Update
Done an overhaul on everything for the kernel. decided to switch from QAEP to AOSP.
Reason for the switch, I noticed with AOSP I am able to not only download the kernel/msm4.14 common folder but it also downloads build, prebuilts, prebuilts-master folders with everything included.
Differences aside from what I mentioned above.
AOSP common-4.14 comes with up to date builder, gcc, clang, etc. But when I download the release tag for example, LA.UM.9.1.r1-06700-SMxxx0.0 at codeaurora on the otherhand, it only downloads the common folder and no extra folders for it.
So then in turn. you have to go on codeaurora and download by using git clone, the build folder for what ever android version it is. for example, I had android version 29 (r29) though it does not exist in the branch list on codeaurora so i went with 28.
I should also note that making the change from QAEP to AOSP I started again with the kernel source.
With making the change, I have noticed improvements right away, but also I noticed that having CC=clang, the build would not work untill I also put in HOSTCC=gcc. guessing its to do with the AOSP version being a little different. still using QualComms LLVM clang compiler for everything clang related.
Spoiler: Problems I have so far.
***Error-1***
Have it building but get this spam, been trying to solve it.
***Error-2***
This error pops up when using LD=ld.lld
this is what is set in the build.config
***CONFIG-1***
LD=ld.lld
LD_LIBRARY_PATH=toolchain/llvm-Snapdragon_LLVM_for_Android_8.0/prebuilt/linux-x86_64/lib/clang/8.0.6/lib/linux/aarch64:$LD_LIBRARY_PATH
export O=out/android-4.14 LD_LIBRARY_PATH
**RESULTS**
***CONFIG-2***
LD=ld.lld
HOSTLDFLAGS="-fuse-ld=lld" (added it so i can modify)
LD_LIBRARY_PATH=toolchain/llvm-Snapdragon_LLVM_for_Android_8.0/prebuilt/linux-x86_64/lib/clang/8.0.6/lib:$LD_LIBRARY_PATH
export O=out/android-4.14 LD_LIBRARY_PATH
**RESULTS**
Same as above.
Spoiler: Config commands
This right here may have just solved all my problems. can confirm in all my config tries. Never once thought to put aarch64-linux-android before all variable values.
SOURCE: https://developer.android.com/ndk/guides/standalone_toolchain
# Tell configure what tools to use.
target_host=aarch64-linux-android
export AR=$target_host-ar
export AS=$target_host-clang
export CC=$target_host-clang
export CXX=$target_host-clang++
export LD=$target_host-ld
export STRIP=$target_host-strip
Also discovered that LD=ld.lld is for clang compiler. could be why the above Problem is happening.
This is using the toolschains without NDK, may have to put qualcomm and gcc in NDK and path them.
So after trying to downgrade to android 10 from 11, had no luck in doing so.
So now sticking with android 11 and I can safely say that I have reached a mile stone.
I ended up downloading android 11 R30 and using all the tool chains from AOSP while still using Qualcomm's LLVM compiler 8.0.6 as REAL_CC. But the clang pre-built path is clang from AOSP. Just trying to work out how to include the Xiaomi audio source. Unable to work out where to put it. Still testing, have not given up.
Hi @Squida, where is `mods/wlan/qcacld-3.0` from, the qcom talos referenced above in BoardConfig.mk?
Do you have an exact link to the repo?
In the meantime I can confirm I am missing something form the kernel. If I build everything myself and replace _just_ the kernel (with my dtb appended etc) it has sound/wireless, so knowing what wifi / audio module to link in seems the way to go.

Thanks, I think I get now what you're saying with 'talos', I poked at those repos now.
It seems to me the modules are built out of tree, as they don't appear in the extracted kernel config. (See https://github.com/b100dian/Xiaomi_Kernel_OpenSource/commit/0f4b062ef806aaad6ad02e2efd87809e8b7250c6).
Also, having dlkm from https://source.codeaurora.org/quic/la/device/qcom/common/tree/?h=LA.UM.8.9.r1-03800-sm6150.0 does not seem to help automate the build, I get all sorts of errors when AndroidKernelModule.mk is included and it includes back the AndroidKernel.mk..
Getting these into drivers/staging seems easier at first but..for now, I've only managed to build wlan.ko but that still errors out with `wlan: disagrees about version of symbol module_layout` :-S

It seems you are having a similar issue.
When doing everything I have done so far, The biggest wall for me is getting <LD=LD.lld> to work properly, I either get clang error with a file having a linking problem with using clang from QQ llvm compiler. And when I switch over to using AOSP's 4.14 stable kernel prebuilts-master clang. It works but then another error to do with CPU timer pops up. Which was originally because of using gcc instead of clang in the CC=clang environment variable, or removing it out of the build.config file.
i myself did a major overhaul of Ubuntu and have upgraded to LTS 20.04 from 18 bionic.
Noticed some things right away.
When you install gcc-multilib and g++-multilib. You get version 9 instead of you being on Ubuntu bionic and getting version 7. Also faster in general with general use of the operating system using Oracle vmbox. On windows 10.
Apart from linking errors, kernel is buding but only with not having LD=LD.lld in the build.config file.
Spoiler: wifi-info
And for the wifi qcom. Mods folder I added manually. Inside the devices source folder. Then copied WLAN sources inside and renamed the folder to just WLAN.
Spoiler: where I am at now
I have got both android 11 and android 10 kernel and ROMs. Also went and downloaded the kernel for coral. That's how I found out about the wifi and how I got a lot of the settings for the build.config.
I am gonna have a break on this whole thing, gotten to a point where with android 11 Xiaomi Phoenix. I get one error with a file in kbuild, using the same config settings for android 10. I get none. Apart from the qcom space which is either DTC not working or failing at some point. Not sure if we need to use LD=LD.lld I have been reading it is not needed due to the builder choosing the correct one for you.
Overall though it builds. Just the spam for qcom warnings I just can not get rid of and it's to do with the sensors.
If anyone has information on what causes the qcom spam. Please let me know, thank you.
Plus this all started with vmlinux not working right. Something to do with channel scratch. Can not fix it.

stackoverflow.com
Key part taken from above link.
**Its hard to build pure AOSP than other ROMs. While building a custom ROM a lot of components wont work**
I think for our devices we have no choice but to use QAEP instead of AOSP, it explains why it fails to build properly. we first need a full working rom and then I think we can move over to AOSP and modify lets say, coral device and match it for our device. Though I think it is just easier using QAEP and why QAEP exists in the first place.
When I used QAEP, I got the SDCLANG problem, the build process according to the Micode git wiki, section "How to use" explains on how to configure and by the looks of the guide. It seems simple as cooking a boiled egg with only a couple of modifications to a device tree and adding your kernel to the kernel folder. It is supposed to build. I myself get SDClang path problems when using QAEP though.
I will go back to QAEP but i will be using all android 11 sources. due to unable to downgrade my phone from android 11 to 10. Having issues at the moment with TWRP installing. Shows my folder structure folder and file names. all random characters.
I will update as i get further in building the kernel and rom
Spoiler: Thoughts2
So I am now merging the built kernel into the kernel directory of AOSP 10. Made a folder called common and moved the built kernel into it. Also made a folder called prebuilts and put in all the .gz into it under a folder called 4.14. discovered that the AOSP 10 picked up the common folder with the built kernel but is having errors with Android.bp, will update as I find out more. Right now, just tinkering.
This is the issue when you have the build tools outside the source folder.
Could be a path I have not set properly. once I removed the command from POST_DEFCONFIG_CMDS="" it is now building.
Couple of things to note.
REAL_CC= I believe has now changed to HOSTCC=. Command is not found in any files in the build directory of the AOSP 4.14 STABLE Kernel.
QualComms LLVM 8.0.6 Compiler does not contain clang files. you still need to either download it, or just use the one in AOSP 4.14 Stable kernel, plus the clang version in AOSP stable kernel is a later version and also contains clang version for android 10+ instead of android 9.
New error I get after changes mentioned above are made.
Not sure where to put -fPIC to make the command function.
Fixed it, was a pathing issue with folders.
But now I am stuck now on finding out the directory for LD_LIBRARY_PATH=
Code:
DTC arch/arm64/boot/dts/qcom/apq8016-sbc.dtb
dtc: error while loading shared libraries: /home/avm/dev/source/kernel/prebuilts-master/ndk/toolchains/llvm-Snapdragon_LLVM_for_Android_8.0/prebuilt/linux-x86_64/lib/libc++.so: file too short

CC lib/rhashtable.o
Spoiler: Extra Discovered Info
${ROOT_DIR} is used. With it and you don't need to export it. Builder already knows what it is. so you use it like this for example
************************************
CC=${ROOT_DIR}/path-to-QQ_LLVM_COMPILER clang binary file, located in bin folder.
Also do this for ld.lld
LD=${ROOT_DIR}/path-to-ld.lld
************************************
Found another odd thing that happens
Having CC=PATH-TO-QQ-llvm-compiler/clang with CC_PREBUILT_BIN as aosp's location and HOSTCC=clang
It builds.
But with LD=
It fails.
I try using QQ-LLVM-Compiler as CC_Prebuilt_bin=
Fails.
So far I have managed to get to this point.
And can safely say that using QualComs LLVM 8.0.6 compiler does not work with android 10 so stick with AOSP's prebuilt clang either in Kernel stable git or AOSP android-Number-Revision
Again, REAL_CC does not work, nor show up in the enviroment as a used command.
These below all do.
<CC=>, <HOSTCC=>, <HOSTLDFLAGS=-fuse-ld=lld>, <NM=llvm-nm>, <OBJCOPY=llvm-objcopy>, <HOSTLD=>, <LD=>,
HOSTCC= will use what is put in CLANG_PREBUILT_BIN=
CC= you are able to add QQ-LLVM-COMPILER's clang and it will run.
Proof of QQ-LLVM-COMPILER failing, when using it for <CLANG_PREBUILT_BIN=>
Instead of using AOSP's clang.
So far that is all I have seen pop up.
All these changes were done with the Kernel AOSP-COMMON-4.14-STABLE build, kernel, prebuilts, prebuilts-master folders and then with the devices source in a folder with a build.config file in the same location as the AOSP-kernel build folders. this all seems to work, Only thing I lose out on, is using POST_DEFCONFIG_CMDS="" to use make menuconfig.
Reason that make does not work is because according to AOSP coral's kernel you have another build.config file which is with the build folder, prebuilts, master-prebuilts folders which connects to the main build.config.common and clang config that has the extra commands. So in turn I do not think we use LD=ld.lld
We let the builder choose it for us.
95% sure that the DTC is what is causing qcom to have that warning spam.
Device tree compiler (DTC) linking seems to be the full cause of all the issues.
Okay to prevent fixdep.c:105:10: error all you need to do is have HOSTCC=gcc and it works. so then in turn. You can now use QQ LLVM Clang compiler in CLANG_PREBUILT_BIN= instead of AOSP.

Spoiler: Still going
Still going at it, manage to find out a couple of things.
If your build is failing due to files missing, check your build directory and make sure the files in the path folder and in Linux-x86>bin folders are indeed "symlinked" something I was unaware of with Linux due to me being a windows user. none of the icons can have an X on it. it means its broken. this solved a ton of my issues during Rom building.
the build folder itself is a symlink folder. (Not all files)
Just locate and put files in correct places. so instead of having a folder called toolchains, like we are told on the Micode wiki, etc. If you use the AOSP-kernel build, prebuilts, prebuilts-master. which contains all kernel and build tools. and are already linked. so then you just add QQ-LLVM-Compiler to either prebuilts or pre-builts master and link it in the config.
If you do all this correctly and having all files in the proper location, you should not have any more build errors in regards to missing files.
Summed up
Build directory contains symlinks to binary files which are located in prebuilts and prebuilts-master. you need all 3 folders in the device source root directory.
Inside the build directory you will find a file called build.config, its not a config. its a symlink for one. Rename it to the build.config.Aarch64 for example, or what ever your config is called located in your root devices source directory. this solved a **** load of my problems.
The problem I have now is actually got to do with Repo, AOSP, QAEP. found out using the manual install method of repo makes it so you can download off google when you have the pgp key installed. but having it installed this way, stuffs up gpg for QAEP. I am looking for a way to merge all PGP keys in one location.
and to get QAEP downloading without showing this error.
All you have to do is remove the manual repo you installed and then also deleting the .repoconfig folder and .gnupg folder.
Then install repo with <sudo snap install git-repo>
it will work, you will get a public key under john doe and it will use CAF as well. problem is. You lose out on public key to AOSP and also the repo that is inside the AOSP folder needs to be replaced. trying it just causes errors though.
What happens when you do above by removing the manual repo and adding the snap git-repo
So why does it matter that I need both public keys to work?
Because I am using AOSP and also QAEP for testing.
I'll be sticking with the snap instal git-repo for now. i'll have to work out how to add the key from AOSP.
**Error when going back to AOSP**
**what happens when you delete the repo folder inside .repo of AOSP**
Only way I got it to work is by removing the snap install version of repo and install the manual way.
But then I lose out on CAF.
Think i may have worked out what is happening with the keys. 2 folders are being made. .repoconfig and .gnupg.
.gnupg only gets created when using AOSP pgp key.
and there is a gnupg folder in .repoconfig, might be a command to merge the files.
this command below makes it so you can change the name.
--config-name
put it at the end of the repo init command.
from what I understand for the tucana_user_defconfig.
#CONFIG_BUILD_ARM64_DT_OVERLAY does not need to be set. for mi 9, yes. not for mi note 10. Just pulled the defconfig from my device using the command below.
**EXTRACT DEFCONFIG FROM DEVICE**
MSM devices
CMD> adb pull /proc/config.gz
files appears as config.gz in same directory
I should also note that I ran 2 builds one with DT_OVERLAY=Y and then one =N
the outcome was with the change of CONFIG_BUILD_ARM64_DT_OVERLAY=n
That is not how it is setup, the proper way to disable it is as follows.
#CONFIG_BUILD_ARM64_DT_OVERLAY is not set
I got a bigger file size for Image.gz-dtb. instead of under 20MB
Have it on so you can extract DTBO and dtb files. having it off stops it from extracting.
THIS error or what ever the hell it is, is driving me insane.
My understanding is that DTBO (overlay), when enabled, ends up in dtbo.img, and when disabled, probably ends up in dtb which is appened to the kernel Image.gz.
The gsi_write_channel_scratch error is... maybe this helps? https://github.com/ClangBuiltLinux/linux/issues/931#issuecomment-599681910

You sir, are a Legend!
Okay So if I am reading that right.
If you mean DT_OVERLAY=y in defconfig, makes it so I can get the dtbo.img file. I tried adding the dtbo.img to the list of files for extraction and with it on, no dtbo image is made nor found, with it off. still the same thing but unable to extract any dtb or dtbo images from the boot directory. have to have it on.
dtbo.img just does not want to extract for me.
Again, using the clang config and not the mi 9 config used on Micode wiki.
the Micode Wiki settings do not work correctly. you lose out on about a GB of stuff and I know its a DTC issue I have been having due to the Qcom spam.
I have reduced the space though so now you can actually scroll through the whole build process, including the spam.
I will definitely be looking into that solution for channel scratch.
Also if you could please show me the config for the SDClang settings you put it to get it to detect. I tried looking over your git page and failed to understand why you have it in boardconfig.mk and if lineage has other files for the device.
Reason being is because on QAEP it talks about SDclang-3.8 and i have no idea where it is.. Supposed to be in QQ-LLVM-compiler and you copy it to the prebuilts folders, it just does not exist to do that.
the major problem I have is building the device tree when building the kernel. from my understanding, Xiaomi have set it up so DTC creates a Device tree for you. well that is the part that is failing and the whole reason why I can not make a rom.
My guess because you are using lineage sources, everything I am talking about. they already did for you. I am trying to do it all manually. learning purposes.
Okay so it turns out, we need LD=ld.lld
Though we must modify files, this is ridiculous just to get your own rom for xiaomi devices.
This thread below may have the solution for me and an easier one then having to modify files manually. Might have to update the Devices Kernel to the stable aosp 4.14 kernel. this is my theory anyway.

Of course, this is the reason. I don't know exactly how the lineage build scripts generate dtbo.img. There's make bootimage, make vendorimage and maybe make dtboimage too. Probably this command helps you generate it, but I don't think I had success with that: https://forum.xda-developers.com/t/...nel-dtbo-for-redmi-k20.3973787/#post-80354635
The image size differs and the one created by lineage build scripts is the same size as the original one.
I also have console spam when the device tree is generated, I just didnt sweat on it as being an error.
BoardConfig is probably central to the lineage build, but I assume the variables set here are available to kernel's make commands.
For a lineage-less built I used the first two commands here: https://gist.github.com/b100dian/40c8dbe746ff181aff71ee10a75a5f3c (the rest of the things are my attempts to construct back the boot.img with the kernel).
To actually boot the kernel you can gzip it, and append the dtb file to it (
like
Code:
cat Image.gz dtb > Image.gz-dtb
).
, and _then_ reconstruct a deconstructed original boot.img with that (w/o the --dtb parameter if I remember correctly). But I think kernel output already has -dtb concatenated in out/arch/arm64/boot

Above solution might be the key thing to solving my issues with DTC. i can safely say I never once put the ARCH= and SUBARCH= in DTC_EXT= this may have solved it.
As for the rom building itself, I may have to use AOSP over QAEP, due to the whole SDCLANG issue

Those issues are all related to QAEP, I have less problems with AOSP.
Just don't have a device tree for it. that is why I need DTC working perfectly.
For what it is worth, tried looking for a default device tree that was not based off lineage-os. No luck thus far.
But isn't the device tree what's in arch/arm64/boot/dts/qcom/ in the kernel sources?
There's even a Makefile there where you can see CONFIG_BUILD_ARM64_DT_OVERLAY in use

Lmao holy ****, I think I know where I stuffed up. I was navigating extract only at boot. Did not go further then boot directory lol. I'll test now with navigating to qcom. Thanks for the tip.
***UPDATE***
Managed to work out why all these problems are occurring.
Okay so from what I understand, there is 2 building methods.
1. Using terminal and using export commands.
2. build.config file
To test the theory to make sure that indeed there is a double up on builds, I decided to put the whole Micode Mi 9 export guide into the build.config that I have (made a backup of it) after executing it did indeed show errors.
so then I investigate how it is failing and it came to my attention that the export method for the make defconfig and then build is seperate for build.config.
for the kbuild, we issue the environment variables for example, these below.
When I say its Kbuild variables, it could be clang or gcc. Not 100% sure though.
Spoiler: Kbuild Environment Variables
# PRE_DEFCONFIG_CMDS
# Command evaluated before `make defconfig`
#
# POST_DEFCONFIG_CMDS
# Command evaluated after `make defconfig` and before `make`.
#
# POST_KERNEL_BUILD_CMDS
# Command evaluated after `make`.
#
# EXTRA_CMDS
# Command evaluated after building and installing kernel and modules.
#
# DIST_CMDS
# Command evaluated after copying files to DIST_DIR
#
# VENDOR_RAMDISK_CMDS
# When building vendor boot image, VENDOR_RAMDISK_CMDS enables the build
# config file to specify command(s) for further altering the prebuilt vendor
# ramdisk binary. For example, the build config file could add firmware files
# on the vendor ramdisk (lib/firmware) for testing purposes.
Spoiler: extra-info
and instead of having "make" command by itself I put it for example in PRE_DEFCONFIG_CMDS="make <code>*
and it will add in REAL_CC, etc to the defconfig and upon making the build it should inturn do the rest.
Does anyone know the environment variable for kernel build so i can then put in the make command for the build and include REAL_CC=, etc. I managed to get the first make command for the defconfig working.
PRE_DEFCONFIG_CMDS="make O=out/android-4.14 REAL_CC=${PWD}/prebuilts-master/ndk/toolchains/llvm-Snapdragon_LLVM_for_Android_8.0/prebuilt/linux-x86_64/bin/clang CLANG_TRIPLE=aarch64-linux-gnu- tucana_user_defconfig"
I just now have to get the below command working. not sure what environment variable to put it under.
make -j$(nproc) O=out/android-4.14 REAL_CC=${PWD}/prebuilts-master/ndk/toolchains/llvm-Snapdragon_LLVM_for_Android_8.0/prebuilt/linux-x86_64/bin/clang CLANG_TRIPLE=aarch64-linux-gnu- 2>&1 | tee kernel.log
Found it!
By searching in build directory then build.sh file.
and *_setup_env.sh* has settings as well that will help.

Better to use CAF for MSM devices.
[REFERENCE] Merge latest CAF Tag in Kernel
Introduction: Hello folks! In this thread I will be guiding you about how you can merge latest CAF tags in your CAF based kernel. Many people who just started compiling the kernels still don't know how to merge a CAF tag because there isn't any...
forum.xda-developers.com
Upon further research on the topic of MAKE_ARGS=$*
from what I now understand and please keep in mind, I am in no way a programmer or good with Linux overall.
I think the $* symbol is a value itself, so from my understanding. If i use lets say $S=Something I have just made an variable that will be used in MAKE_ARGS=$*
If my theory for this is correct, this is how I add in the make variables for the last build command to start the build.
Should be able to do this.
make -j$(nproc) O=out/android-4.14 REAL_CC=${PWD}/prebuilts-master/ndk/toolchains/llvm-Snapdragon_LLVM_for_Android_8.0/prebuilt/linux-x86_64/bin/clang CLANG_TRIPLE=aarch64-linux-gnu- 2>&1 | tee kernel.log
Oh and the config is make commands, found that out as well. you have MAKE and SOONG commands and configs. I so prefer Make variables over Soong. looks easier to read for me.

The build config above is indeed for Mi11, we do not need gsi settings or the 3rd command starting with O=$OUT for Mi note 10 pro
By implementing the changes above, outcome below.
Just now have to resolve kernel issues and this should build with no more issues. it has been a massive adventure.
the errors above are due to remnants of old files from merges that were not undone properly. deleted the devices source and recreated it again. problems are now gone will update on outcome.
I still can not seem to get it completely built. Max Image.gz-dtb file size is 28.5MB so far. and the highest I have gotten. still get VMLINUX issues which tells me just maybe Xiaomi themselves have not updated the build scripts to suite the latest CAF changes.
All speculation at the moment.

Turns out, build config for CC9 Pro. does not exist hence why all the problems Using AOSP's.
I believe it needs to be full modified in order to work with Tucana, due to Xiaomi not releasing a build script for it. so another solution would be to modify or try and use another device on the list in the link to be able to build it. not even export using the Mi 9 works so I have to dig deeper on getting a config and build script for it.

The config does not build vmlinux, DTC properly, dtbo.img. Still working on it.
I also did try first doing the standalone export way. Just constantly getting ld error --fix-something and to fix it, by using CC=clang and HOSTCC=gcc
but then you resort to having to use the build.config file. for some reason the standalone export method just does not work with cc and hostcc
and that is using the QQ LLVM/clang 8.0 toolchain with AOSP's GCC while having 2 directories. toolchain(GCC) and toolchains(QQ-LLVM/Clang) with QQ-llvm/clang's build directory inside the devices source root directory as well, according to MiCode Wiki under MSM-4.14.
Tried attaching the last make command to the DTC_EXT= and it fails, still unable to find the build kernel argument to change the command manually. Only have POST_KERNEL_BUILD
No luck at all with the export combo.
As for the build.config.
I get a build using AOSP'S GCC and QQ-LLVM/CLANG 8.0
But it is not complete.
I also use the build, prebuilts, prebuilts-master from AOSP's 4.14 Common kernel repo.
the reason for this, is because Xiaomi have not released kernel build files for the device. from what I have found.
