[Guide] Compiling your own kernel. - Barnes & Noble Nook Tablet

I have writen this guide so that anyone whom wants to try to compile and customize their kernel can.
LINK
It took me a long time to write this guide, and its pretty through, but if you see something missing please let me know, or post it in the discussion part of the page.
Once you compile the kernel aka zImage you can use hkvc kexec, or use bawks 2ndboot (if your daring enough) With this guide, hopefully we can get others to join the effort of making their own roms, and boot.img

Good write up.
I am having some errors pop-up at the end of compile. Here is my output:

Hmm, was just using whatever was synced with the repo.
Is there anyway you could post or send me a generic zImage from this compile? Trying to get a internal boot.img up and running but it seems to keep crapping out at the kernel (got 2ndboot showing up and ramdisk is in good shape).

Awesome, Ill try that one tonight!

For anyone interested in making your boot.img run off of internal storage (flashing via CWM or other recovery) you will need this file:
http://www.mediafire.com/?zrx5gk32casx55g
Just cat it to your custom_boot.img and flash!
Code:
cat irboot.img custom_boot.img >new_boot.img
Credit for the source for this goes to Bauwks!

It was from Bauwks source. Was excited to get something running and slipped my mind. Edited post!

Sorry for the noobish question, but anyway how can we get a 3.x kernel? What are the difficulties to get it compiled?
I am not sure if I can help. I have some Linux experience compiling software from sources and I know compiling a kernel is not a trivial thing to do, however I would be happy to contribute.

How to you edit kernel.img that is inside the zImage?

simple answer: as posted above, if it doesn't compile properly from HTC, as the last kernel release from them also didn't, it probably won't be an *easy* fix.
warning: the technical method i suggest might only lead deeper and deeper, but it is a generally good strategy to research and resolve compiling issues.
technical research method: without having looked at this kernel source or researched the error, i would start searching for the implicit declarion of function 'arch_has_speculative_dfetch' in the dma-mapping.h file at line 442. it should be declared and setup in some file, so i'd grep through the files for it. grep -irs arch_has_speculative_dfetch /home/smokin/kernel/arch/arm/include/asm/*
depending on the results, the grep search might have to be expanded so i'd move up a level. might have a lot of results to search through but it is usually a great learning experience.
as a beginner, i would suggest watching http://github.com/toastcfh as toastcfh does a great job fixing the error laden kernel source code HTC releases. generally, toastcfh's patched kernels are used by all the popular kernel releases and will more than likely be the base kernel used by cm7.
hope that helps!
Thanks !! That helps alot, considering i wasn't sure if i had the toolchain setup right. I appreciate it.

ah, you didnt mention that before!
if you want to test your toolchain, i'd clone/fork toastcfh's repo for the previous evo 3d kernel release. it should cleanly compile, no issues. that'll be a great test for your toolchain and to give you some confidence in compiling the kernel with *proper* source code.
toastcfh worked some magic to fix htc's last borked kernel release code by pulling files from caf (code aurora forum - code contributor) and probably lots of other complicated coding/compiling tweaks.
hope that helps at least get you ready for the next proper kernel source code!
I took your advice and got toastcfh source and i got the same error with crc. I guess i'm missing something, probably a stupid dependency.

[Q] How to build kernel for I9100G?

Hi, can someone guide me how to build the kernel for I9100G? I downloaded the kernel source from Samsung and extracted. The instructions in the archive are as follows:
HOW TO BUILD KERNEL 2.6.35 FOR GT-I9100G
1. How to Build
- get Toolchain
Visit http://www.codesourcery.com/, download and install Sourcery G++ Lite 2010q1 toolchain for ARM EABI.
Extract kernel source and move into the top directory.
$ toolchain\arm-2010q1
$ cd kernel/
$ make t1_defconfig
$ make
2. Output files
- Kernel : kernel/arch/arm/boot/zImage
3. How to make .tar binary for downloading into target.
- change current directory to kernel/arch/arm/boot
- type following command
$ tar cvf GT-I9100G_Kernel_Gingerbread.tar zImage
Click to expand...
Click to collapse
Looks simple enough. So I downloaded the toolchain from CodeSourcery and installed. I don't quite understand the first line in step 1
$ toolchain\arm-2010q1
Click to expand...
Click to collapse
What does that mean, exactly? Typing it out just like that gives an error.
If I skip the first line, after "make t1_defconfig", I get the error message "make: *** No rule to make target `t1_defconfig'. Stop."
Help, please?
BTW, I'm using Kubuntu 11.10.
Got it finally. Turned out my dump of the kernel source code was bad and some files were corrupted. Plus, crappy instructions, make t1_defconfig doesn't work. Instead I did
make ARCH=arm CROSS_COMPILE=~/CodeSourcery/Sourcery_G++_Lite/bin/arm-none-eabi- t1_defconfig
make ARCH=arm CROSS_COMPILE=~/CodeSourcery/Sourcery_G++_Lite/bin/arm-none-eabi-
Compiling now. Hope for the best.

Doesn't work.

Experienced devs, anyone, help please?
Hi
I too am trying to build the kernel and I am stuck at same error. Can you please let me know how did you resolve this error?
Thanks in advance
Just in case anyone is still looking for solution:
I had the same problem. But managed to compile it successfully, under Ubuntu, using the prebuilt toolchains inside Android's NDK. Simply download, extract and start compiling.
I was able to build kernel successfully using arm linux gnueabi toolchain. Thanks for the help guys. Now I am all set to create a custom kernel
---------- Post added at 10:52 PM ---------- Previous post was at 10:50 PM ----------
The error was coming because of undefined macro for __linux__.
Can be resolved by either replacing it with LINUX or using arm linux gnueabi toolchain instead of arm eabi.
any update ?
or can u share how to build/make a custom rom so i can also try to make a custom rom
thnx!

I guess you are looking on another file.
Code:

I guess there is a problem in dynamic_debug.h in line 75. I guess you need to initialise something.
Here is dynamic_debug.h but I can't find the problem.
I will appreciate any opinion.
Try this method!

I am not much used to kernel related development but I analysed your dynamic_debug.h and found the problem (maybe a problem):
Normally, a do-while loop syntax is this:
Code:
do
{
Statement1;
Statement2;
...
}while(condition);
But I don't see a semicolon in the end of those loops in your code. This maybe a syntax error.
Also analyse these codes:
Code:
#if defined(CONFIG_DYNAMIC_DEBUG)
extern int ddebug_remove_module(const char *mod_name);
extern __printf(2, 3)
int __dynamic_pr_debug(struct _ddebug *descriptor, const char *fmt, ...);
struct device;
extern __printf(3, 4)
int __dynamic_dev_dbg(struct _ddebug *descriptor, const struct device *dev,
const char *fmt, ...);
struct net_device;
extern __printf(3, 4)
int __dynamic_netdev_dbg(struct _ddebug *descriptor,
const struct net_device *dev,
const char *fmt, ...);
Every intialisation has 4 protocols but the first initialisation contain only 3.
Try the above things and tell me back if it works or not.
So, the problem was in Makefile and .config. I compared and added some flags from Mako (from franco) and it worked. I still have some warning/s, some breakpoints but at least now it's working. Anyway, this thread may be useful for all of us. Thanks a lot for help.
Now, another problem.

Hey sarsdani Apologies that I'm quoting you 12 month later. I am getting an identical error in the same file/address as you had when you posted this question. Im compiling stock HTC m7 Android L kernel with Google tool chain 4.8 - android 5.1 r1
You mentioned later on that you changed the Makefile and .config to fix the [-Wmaybe-uninitialized] error. Can you please detail what those changes were or point me to an example ( if you can remember ) I could just change Wmaybe in Makefile to Wno but turning the flag off altogether seems dangerous.
@Joeisgood99 there are two ways to solve this.
1. using a "hack". So, you need to add in makefile (in root folder from kernel source) at KBUILD_CFLAGS: -Wno-maybe-uninitialized \
2. Open that file with the error and asign a value to protocol.
The first option is not dangerous. Why? Because only the toolchain say this. In gcc 4.6, the reason why you don't get this error is because it assign a value automatically to that "protocol", usualy random value but not always. In gcc 4.7/4.8/4.9(or 4.10) this is threated as warning/error.

It's okay i retired the project as of now since trying to modify the kernel source code isn't do anything but causing more errors. I do appreciate any help when everyone has a chance

First time compiling kernel with a governor and I got errors.

I am trying to compile a kernel for my device(kyleprods or GT-S7582 or Galaxy S duos 2) because I havent found any custom kernel out here. Im compiling from source. I tried compiling WITHOUT any tweaks or such, just plain compile after downloading the source, and it compiled successfully. I tried adding smartassv2 but I got these errors after running "make -j1" twice. Can anybody help/guide me? It is really my first time doing these things, because I'm very interested.

Part of the errors can be fixed by adding:
#include <linux/module.h>
at the top. I don't know about the rest, but @xpirt or @InfinityShooter once fixed this problem for the desire x, perhaps he can help? I want to know it myself as well
@diskie

Look in drivers/cpufreq/cpufreq_ondemand.c and include/linux/cpufreq.h for fix

Look in drivers/cpufreq/cpufreq_ondemand.c and include/linux/cpufreq.h for fix

Cross-Compile Error When Building Kernel (Nexus9 Memory Forensics)

Cross-compile error when building kernel (nexus9 memory forensics)
I'm currently following the AndroidMemoryForensics guide (I cannot post a link) on how to extract memory from an android device using LiME. I'm using the flounder_defconfig build configuration and create the .config file using
Code:
make flounder_defconfig
. In order to be able to load the LiME module to the kernel I need to add the following lines to the .config file:
CONFIG_MODULES=y
CONFIG_MODULES_UNLOAD=y
CONFIG_MODULES_FORCE_UNLOAD=y
When I compile the kernel I set the architecture to arm64 (ARCH=arm64) and use the aarch64-linux-android-4.9 toolchain (CROSS_COMPILE=aarch64-linux-android-4.9/aarch64-linux-android-).
When running
Code:
make
I get compile errors saying that "battery_voltage_monitor_on" is undeclared (see below).
If I try to compile the kernel without making the changes to the .config file I get no compile errors.
Am I missing something here, e.g. some package, or have I done something wrong to cause this compile error?
I tried to search for a solution online but have had little success so far so I hope I have better success here
Thanks in advance!

I'm having same issue on my build. Fine without modules but throws linker errors when enabled.
