Hi All,
I need some help to compile Sony stock kernel for my Xperia ZU on Ubuntu 15.04. I downloaded the latest source from sony developer site:
14.5.A.0.270.tar.bz2
and downloaded Doomlord's pre-built tool chain from:
https://github.com/DooMLoRD/android_prebuilt_toolchains.git
and exported the path with arm-linux-androideabi-4.7:
export CROSS_COMPILE=/home/vishwas/android/android_prebuilt_toolchains/arm-linux-androideabi-4.7/bin/arm-linux-androideabi-
Compilation started with:
make clean && make mrproper
Then, defconfig for Togari:
make ARCH=arm CROSS_COMPILE=$CROSS_COMPILE rhine_togari_row_defconfig
and then compiled kernel using:
make ARCH=arm CROSS_COMPILE=$CROSS_COMPILE -j4
I get error as:
Code:
MODPOST vmlinux.o
ERROR: modpost: Found 2 section mismatch(es).
To see full details build your kernel with:
'make CONFIG_DEBUG_SECTION_MISMATCH=y'
To build the kernel despite the mismatches, build with:
'make CONFIG_NO_ERROR_ON_MISMATCH=y'
(NOTE: This is not recommended)
/home/vishwas/android/14.5.A.0.270/kernel/scripts/Makefile.modpost:98: recipe for target 'vmlinux.o' failed
make[1]: *** [vmlinux.o] Error 1
Makefile:936: recipe for target 'vmlinux.o' failed
make: *** [vmlinux.o] Error 2
If I compile with "CONFIG_NO_ERROR_ON_MISMATCH=y", then there is no error in compilation:
make ARCH=arm CROSS_COMPILE=$CROSS_COMPILE CONFIG_NO_ERROR_ON_MISMATCH=y -j4
But, I am not sure this is correct or not.
Can anyone please help me on solving issue related to 'vmlinux.o' ?
Edit: The issue was with toolchain. After pulling the arm-eabi-4.7 tool chain from git and using it resolved the issue:
git clone https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/arm/arm-eabi-4.7
Thanks
Can anyone please help me with the equivalent command to compile kernel for Sony Xperia Z ultra (C6802) 5.0.2 stock kernel, below command I got for Sony Xperia S for JB:
python mkelf.py -o kernel.elf [email protected] [email protected],ramdisk [email protected],rpm
Or, will above command work with Sony Xperia ZU 5.0.2 as well ?
Edit: Never mind, got the DoomLord's link to compile kernel.
Thanks

Hello,
I want build the kernel of Xperia S but I hava this error :
Code:

Thank you !
Solved
Solved I write in the Makefile the flag --disable-werror. Nice
Edit : BUT i have a new error

You shouldn't have to edit the Makefile. Are you using the tool chain recommended by Sony? Make sure your path selects them before anything else. Also I would reset locale to C before compiling ("Erreur"?!), it may play some tricks.

You find the specific instructions for the Xperia S at http://developer.sonymobile.com/wp/...-archive-released-with-building-instructions/ referring to the kernel building howto at http://developer.sonymobile.com/wp/2011/05/06/how-to-build-a-linux-kernel/ recommending you to use the tool chain at https://sourcery.mentor.com/sgpp/lite/arm/portal/[email protected]=lite
Follow those instructions before start tinkering with Makefiles, tools, build environment etc and I'm sure you'll succeed.
And reset locale to C! I.e. unset the LANG and LC_* environment variables in your shell before running the build scripts.

Sorry, but I'm no mind reader. "does not work" is not sufficient information for me to reply anything helpful to.
The basic is, if you don't know what you are doing, do it by the book. Still not working? Ask for help. Sony Xperia has presented quite a verbose instruction about how to compile their kernels. Try following this before choosing your own tool chain, edit Makefiles and so. When you get problems, read the instructions more carefully and/or ask the community (hi!) for help, with somewhat more detailed information about what you did and how it failed. The more verbose information you present, the more likely you are to get a useful reply.
Best of luck.
------------------
(edit)
A curious question, why do you want to compile a new kernel? I get the impression this is not your field of expertise, and maybe you are trying to achieve something somewhat more complicated than needed.
Hello,
I encounter the same kind of issue. Does anyone could help me ?
I work in an Ubuntu PC (10.04).
I have downloaded the toolchain for Linux from sourcery.mentor.com (arm-2012.03-57-arm-none-linux-gnueabi.bin)

You need android-ndk-r5b to compile the Xperia kernel source. I.e. you can not use the latest NDK.
Thanks a lot for your answer
Unfortunately, I didn't find android-ndk-r5b for Linux.
Could you kindly indicate me where I can get it ?
thanks !

Thanks again, I really apreciate your support !
I have downladed and extracted android-ndk-r5b to my Ubuntu station.
it seems that is is not a built version, right ?
I have tried to navigate in the documentation, but it does not look so trivial...
Would you know how to simply compile it ?

It's compiled ready to use.
Read the documentation at http://developer.sonymobile.com/wp/2011/05/06/how-to-build-a-linux-kernel/
Replace the toolchain path with e.g. "CROSS_COMPILE=/opt/android-ndk-r5b/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/arm-linux-androideabi-" and you are good to go.

Only specify ONE toolchain ...
Also, I'm note quite sure if I used 4.4.0 or 4.4.3, since both are included in the same r5b distribution. You can also try;
CROSS_COMPILE=~/Toolchain//android-ndk-r5b/toolchains/arm-eabi-4.4.0/prebuilt/linux-x86/bin/arm-eabi-
Thank you kuisma.
Sorry it was a copy/paste error, I had for sure specified only one toolchain.
So I am making a new test with CROSS_COMPILE=~/Toolchain/android-ndk-r5b/toolchains/arm-eabi-4.4.0/prebuilt/linux-x86/bin/arm-eabi-
I'll keep you informed
---------- Post added at 11:51 AM ---------- Previous post was at 11:15 AM ----------
It built, thanks again for your support, kuisma !
Not sure it is still in the scope of this topic, but continuing to execute the instructions found in developer.sonymobile.com/2011/05/06/how-to-build-a-linux-kernel/, I have some questions regarding Step C, absolutly not clear for me
What should I do exactly to prepare my boot.img ? What have I to do to create a ramdisk.img file, or where can I find it ? (in fact I do not know what it the ramdisk in the picture...is it required ?)

Start with the original root filesystem from the standard boot.img you are already running.
You'll find my tool working with boot.img here: http://whiteboard.ping.se/Android/Unmkbootimg
Also, read the links on the page my signature links to, to get more information about how to build boot images, root file systems etc.
The ramdisk contains the root filesystem, and yes, it's very much needed.
Ok understood
last point: how to retrieve the boot.img from my Xperia S phone ? (that is already unlocked)

Hello. Can not building AOSP 4.2.2 using the repository PolishBlood Project.
Synchronizes with the repository manifests jb-4.2. Then I enter the command:
source build / envsetup.sh
lunch
Choose from the list: PolishBlood_coconut-userdebug
Then I enter - make -j5
After a time, to give an error number 1 after re-entering the make -j5 - mistake number 2 (there is something associated with the kernel firmware). 2 times checked back files from the repository by typing: repo sync, then repo sync-f. Now I try again to rebuild the firmware at the same time clarify the details of errors. While the question:
Instructions on how best to collect the firmware repository PolishBlood Project?
PS: SDK, ADB, JDK stand on their compiler does not complain.
My 4 core CPU, I introduce make -j5
That's what a mistake has issued:
make[4]: *** [arch/arm/boot/compressed/piggy.lz4] Error 1
make[3]: *** [arch/arm/boot/compressed/vmlinux] Error 2
make[2]: *** [zImage] Error 2
make[1]: *** [sub-make] Error 2
make[1]: Leaving directory`/home/slava/android/kernel/semc/msm7x30'
make: *** [TARGET_KERNEL_BINARIES] Error 2
make: *** Waiting for unfinished jobs...
Problem was solved by the fact that the set lz4. Now I have another question:
Instructions on how best to compile AOSP 4.1.2 from the repository PolishBloodProject? I synchronized the same repository version of android 4.1.2, but the compiler complains that device_specific_code etc. - from cyanogenmod. More bugs lay out later.
You need to post the exact error using
Code:
tags, then we can try to help you ;)
Okay. I eventually resync all the files to the repository, and compiled with the 4.2 repository PolishBlood. I want to compile the 4.1 repository PolishBlood, but not all files are synchronized from the repository by:
Code:
repo init -u https://github.com/PolishBloodProject/manifest.git -b jb
It feels like not all the files are synchronized with the repository
Question: Is everything I'm doing right, for synchronization and compile AOSP-firmware repository PolishBlood?
Background :
So I was asked by some people on how I compile kernels so I am just posting some stuff related to same .
This is a beginners' tutorial and is mostly relevant to Xperia 2011 MDPI section . It might work on other sections but I won't be offering any guarantee .
For whom is this tutorial designed for ?
People who like to read stuff and can read stuff ,people who have desire to learn something and would like a more hands on approach .

Requirements :
Linux Distro installed on PC .Thats preferrable . Search,read ,install.It's not rocket science .
I am using Linux Mint 13 in this tutorial . Ubuntu,Debian and Ubuntu/debian based distros should be similar to setup.
This tutorial should work on other distros too ...

I am not going to support questions/doubts regarding
Cygwin on Windows
Linux installed in Virtual machine
Live Linux distributions .
I would rather spend time fixing issue then figuring out how to do same thing in another environment .
Get tools for stuff you need not know
install these tools via relevant package manager
Code:
build-essential,bzip2,gcc-multilib,g++-multilib,git,gnupg,libncurses5-dev,lib32ncurses5-dev,lib32z1-dev,kernel-package,ia32-libs,zlib1g-dev,zip
e.g for Linux Mint it's
Code:
sudo apt-get install build-essential bzip2 gcc-multilib g++-multilib git gnupg libncurses5-dev lib32ncurses5-dev lib32z1-dev kernel-package ia32-libs zlib1g-dev zip
Next download Android SDK and configure adb and fastboot . Use the amazing service known as google to set up .Test run if they work properly .

Some information :
Q1:What is boot.img ,kernel and ramdisk ?
Boot.img or the file you flash to boot partion .It is actually made up of two parts.
zImage is the actual kernel .You can't edit it .You have to recompile it using the kernel sources
initrd.img is the ramdisk .Using tools like Android Kitchen or kernel-tools-master you can edit it .
More about each part in relevant section .
Q2:How do you manipulate ramdisk,change bootlogo ?
A: Check @dsixda 's Android Kitchen or @championswimmer 's kernel-tools-master
Q3:Where does BOOTCLASSPATH lie in ramdisk ?
A:It's present in init.rc
Q4:Where do you change the path to wifi libs ?
A:Check init.semc.rc
Steps I use to work with Boot.img
Modify Ramdisk with Android Kitchen completely .
Use Stock kernel
Repack using Android kitchen
Check if kernel boots
if it does than you have a working ramdisk.
Now you just have to change zImage after compiling it.

to fix toolchain errors
I peeked into wedgess' Lupus and kast's Kappa sources
https://github.com/garwedgess/LuPuS-STOCK-ICS-Xperia2011
Toolchains :
Toolchains are the compilers (cross compilers to be exact ) with which kernel is compiled .
There are tooooooooo many compilers .
I can't test everyone
The best way is to go for compilers which are proven to be work
Path to the compiler .
Before compiling kernels the path to cross compiler must be exported using
Code:
export CROSS_COMPILE=path_ to_compiler
e.g.
My 4.4.3 compiler lies in
/home/user/android-ndk-r8d/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin
In the folder of the toolchain the compiler is present ,all the tools are prefixed with arm-linux-android-eabi-
so the path to compiler becomes
Code:
export CROSS_COMPILE=/home/karan/xd/android-ndk-r8d/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin//arm-linux-androideabi-
Some have arm-eabi- as prefix ,some have no prefixes .Adjust the path accordingly
The usual path of compiler is in bin folder .
Toolchain sources :
Source no 1 : Android NDK
http://developer.android.com/tools/sdk/ndk/index.html
Download the one which has above 360MB of download size ...I have the older version and it has 4.4.3,4.6,4.7
Source no. 2 : Github of @DooMLoRD and @wedgess
https://github.com/garwedgess/toolchains

Doomlord has 4.4.3,Linaro 4.6.2,4.7
Wedgess has 4.4.3 ,Linaro 4.6.2 , Linaro 4.7.3
Use git clone command to download the toolchains
e.g

FAQ:
What Toolchain works on Stock sources ?
On pure Stock ROM ,without any modification I have been able to compile only on the 4.4.3 by DoomLord ..I would recommend using that one.It works fine on both ICS and GB stock kernels .The kernels boot fine
What should be done so that that you can compile with other toolchains ?
A:There are certain changes in the main Makefile which need to be carried out
Open the main makefile and search for
KBUILD_CFLAGS
Replace
Code:
KBUILD_CFLAGS := -Wall -Wundef -Wstrict-prototypes -Wno-trigraphs \

KBUILD_CFLAGS := -Wall -Wundef -Wstrict-prototypes -Wno-trigraphs \
-Wno-unused-but-set-variable -Wno-uninitialized \
-fno-strict-aliasing -fno-common \
-Wimplicit-function-declaration \
-Wno-format-security \
-fno-delete-null-pointer-checks
Now open
Code:
/include/linux/netfilter/x_tables.h
and delete these lines
Code:
const struct xt_match *match;
const void *matchinfo;
That should fix 4.6.2 & 4.7.3 erros
The Linaro 4.7.3 toolchain requires editing the /arch/arm/boot/compressed/Makefile.Honestly ,peek into kast's Makefile ,since I was able to compile only by applying his Makefile fix .
For others ,Please check logs and correct errors
Making changes to source :
Governors,I/O schedulers & Overclocking :-
Check XDA university's thread
http://xda-university.com/as-a-developer/adding-features-to-your-kernel
It's very well written and i don't want to repeat the same stuff
Making changes to Partition on MDPI
this is a post I made earlier :Read it for details ..

Compiling the kernel :
First Open Terminal in the main kernel directory .
It is in kernel folder of stock sources .
Step no. 1
Export the architecture .Our phone use arm architecture . Some phones use x86 architecture like our phones .Hence the architecture must be defined before compiling .Do this by .
Code:
export ARCH=arm
Step no. 2
Export the Cross Compiler since thats what will be used to compile kernel .
Code:
export CROSS_COMPILE=/home/karan/a/android_prebuilt_toolchains/arm-linux-androideabi-4.7/bin/arm-linux-androidwabi-
Step no. 3
Clean earlier builds . Important before recompiling
Code:
make clean && make mrproper
Step no. 4
Specify the defconfig
The default config for xperia is in /arch/arm/configs ...they are like semc_mango_defconfig or whatever phone you are using
use
Code:
make semc_mango_defconfig
Step no. 5 Editing: optional
Make edits via menuconfig or xconfig :
This allows you to enable/disable governors,schedulers,filesytems ,modify other parameters which were predefined in defconfig
Code:
make menuconfig
OR
Code:
make xconfig
menuconfig is Command line tool while xconfig is the graphical interface .
You can save the config and use it later and use that as defconfig next time instead
Step 6: Compile
Initiate Compiling ....
Code:
make
If you are compiling for first time it's recommended to use
Code:
make
instead of
Code:
make -j2
or whatever . It will help you to troubleshoot errors .Else errors will be thrown ,you wouldn't be abele to view in terminal and there would be no zImage
Step no. 7: Grab zImage and pack it
after successful compiling zImage will be present in /arch/arm/boot folder
Then use Android kitchen to pack it .
Source Distribution :
1)In a tar ball like sony
Just use an archive manager and make a tar archive ...
Advantages : Easy ,hassle free
Disadvantages : Too large in size if modifying very few aspects
2.)Using diff patch
It's like a comparing tool
e.g If I am my base kernel source is Lupus and I have added some tweak then I can create a patch file which can be used on the Lupus source and the result will be my work .It's pretty handy if you are dealing with few files .
Advantages : small size ,pretty handy ,
Disadvantages : Without a proper text editor like Geany ,check patches is a nuisance .The Mesa patch for MDPI has over 1,500,000 lines ...enough to screw with normal text editors
3)Git with github or similar site
It's a fantastic way to upload source .It allows many features to a developer which makes life lot easier .
Advantages : Excellent Version Control
Disadvantages : Steep learning curve .
Git is quite complex for a newbie and it can overwhelm a person .I would suggest reading a lot about git and experimenting thoroughly before diving in .

Peeked in their sources and learnt Stuff
Recommended Text Editor :If you want to seriously dabble with sources I would suggest to use Geany .
It saves a lot of time .It's a must have if you peek a lot into patch files and/or sources .

Thanks for the guide
Now i dont have to search around.
Thanx
@karandpr- a guide like this suits for the android general or appropriate forums!
Why keep it so inside? just a suggestion though
Thanx for this!

usually the error of unknown CPU architecture is because you're using linaro toolchain but without proper definition of CPU architecture in Makefile flags. stay away from linaro for first timer. i would strongly suggest using google vanilla 4.4.3 toolchain. abit old but always work given that the're no actual error in the source itself.
Finally karan:thumbup: Thanks a lot for the guide. Really helpful
Cheers,
Vatsal

Code:

Didn't check the second error .
It's because you are using Linaro 4.7.3
Like i said above
Code:
/arch/arm/boot/compressed/Makefile
You need to change it a bit ...
Compare it with changes of Kappa or Lupus .

I'm not using linaro toolchain but ndk r9b (something 4.8)
i also modified makefile according to your solution i found when searching google in one of the xda thread.

I will take a look at it but for time being ,I would recommend switching to 4.4.3 since it has least erros and the zImage boots fine .
Congratulations karan for finally making the guide will be very helpful for many of us :good:

Hi,
I am trying to build a kernel for rochchip tablet. When I compile the kernel using "make -j4 kernel.img", I am getting the following error.
HTML:
GEN drivers/video/rockchip/screen/lcd.h
Kernel: arch/arm/boot/Image is ready
<path>/kernel/mkkrnlimg: <path>/kernel/mkkrnlimg: cannot execute binary file
make: *** [kernel.img] Error 126
I understood that it is the problem compiling the binary mkkrnlimg. It is an ELF file which has to be compiled on MAC 10.9. Could some one please tell me how to fix it. I already had elf.h added to bin/include. It didn't help
Thanks
Hello everyone,
currently i trying to develop my own Kernel for my Xperia Z2. I installed Ubuntu 18.04 and i think i installed the toolchain in a half correctly.
The Toolchain that i install is under /usr/arm-linux-gnueabi. Now i have some questions..
1. Why it is does exist difference how to build a kernel? Automatic method and manually one?
2. I write export PATH="/usr/arm-linux-gnueabi/bin:$PATH" in the bashrc, but im not sure about this?
3. What is the difference between download a toolchain unpack them and use and installed one through the terminal, like i do it?
4. How i can sure that i installed and set up the toolchain correct?
I will find the answer after try and error of course, but getting early a answer will help me to solve another problems which will come.
Thanks
I get this info by trying compiling something:
HOSTCC scripts/basic/fixdep

As i read, i need a 64 bit library or something.. Who can help?
