[DEV] Compiling *working* a kernel from source

Has anyone done it?
I did a few runs with the m2_att_defconfig and the defconfig I pulled from the stock boot.img but I've had no luck with either. I'm fairly certain I'm repacking my boot.img back correctly, but that could be an issue as well.
I've uploaded the kernel source to github as well as the defconfig I pulled from my phone in case someone wants to save some time.
I wonder if the ominous "QUALCOMM SECUREBOOT: ENABLE" has anything to do with it too.
Anyone have any thoughts? Ideas?
Please stay on topic here
======================================================
Edit
mdeejay is a genius. It works with the following:
Code:
./mkbootimg --cmdline "console=null androidboot.hardware=qcom user_debug=31" --kernel zImage --ramdisk ramdisk.gz --base 0x80200000 --ramdiskaddr 0x81500000 -o ./boot.img

I have been getting nothing but errors, can't figure it out. I'm trying for just stock right now.

try it

Have been working on this 'problem' now for nearly a week with testers (I have the International gsm model) and no luck at all. Tried unpacking/repacking with/without the command line using manaul methods and automatic but always hit a bootloop.
I NEED to be able to work with these boot image for AT&T/VERIZON/SPRINT and also TMOBILE for my US S3 ToolKit so if anyone has any insight what is needed to successfuly repack the boot image please share. I have been working with boot images from NAND backups as that was the only image available to me until yesterday when Adam Lange published the Odin Stock Roms for all the carriers so I will have another go today with those.
@ mdeejay is that a repacked boot image for Tmobile? If so and its worked for you please could you share how you managed it?

yes. its for tmobile
i cant test. i dont have device
you can try same way http://forum.xda-developers.com/showthread.php?t=1584919 create boot img with correct offsets for sgs3
i think its useful for all msm8960 devices

Hey Romanbb I havent had a chance to look at this yet do you mind sharing the params you had to use packing the boot image.
Thanks, Mark.

Haven't got my phone yet, but been doing some reading for when I do and according to this: https://developer.qualcomm.com/sites/default/files/snapdragon-specs.pdf and your latest source edits, it doesn't look like these processors necessarily support all these frequencies (they seem pretty limited compared to the Exynos). do they hold up very well?

I compiled mkbootimg from source, and for some reason it wont let me use the --ramdiskaddr option.
If I take that out then it compiles a boot.img but it isn't bootable.

thansk before sir
but I've finished the build. after the lib folder I compare the results with the original folder cm10.1 alpha 7
was not the same as the results build rom, I try to take a few files in the lib folder belonging cm10.1 alpha 7 that there are no build results in the rom folder.
and turned out to be.
then what was wrong when I build rom, which cause the same contents to the lib folder cm10.1 alpha 7?

Not sure without looking at the code. Do you run 'make clean' before a new build?

Making a mix of this code and a ROM released for the Apollo Lite I get a ROM that stops in the bootanimation.
However now I can 'adb shell' that build so I can send commands to the phone and it executes them well so the system is working but the main UI isn't

Hi Guys,
Can someone please help me?
I'm having trouble while to compile my build.
Firstly I did built my own device and vendor trees, then I had this error. After that I used this thread device and vendor tree still having same error.
Starting build with ninja
ninja: Entering directory `.'
ninja: error: '/system.prop', needed by '/home/neverson/android/system/out/target/product/omega/obj/ETC/system_build_prop_intermediates/build.prop', missing and no known rule to make it
build/core/ninja.mk:151: recipe for target 'ninja_wrapper' failed
make: *** [ninja_wrapper] Error 1
make: Leaving directory '/home/neverson/android/system'
What this error means and how can I fix it? Just for you know I think I have system.prop file, but the error remains.

[TUT] Compile Genom Kernel from Source Code for ONC

Hello everyone,
This is a tutorial on how to compile kernel from source code for our device Redmi 7
Special thanks to @rama982 for making Xiaomi source code usable, upstreaming kernel to latest CAF tag and integrating Wifi drivers
So basically to compile kernel from source code we will have to do 4 steps
1. Setup build environment
2. Install required packages
3. Download source code
4. Compile kernel
1. Setup build environment
Setup your favorite linux distro (I recommend using Ubuntu because it is user friendly).
You use virtual box or install linux to a separate partition if you are a Windows user.
2. Install Required packages
Open up terminal and run this command
Code:
sudo apt-get update
Terminal will ask for your password...This is normal....enter your password and press enter
Then run this command
Code:
sudo apt install bc bash git-core gnupg build-essential zip curl make automake autogen autoconf autotools-dev libtool shtool python m4 gcc libtool zlib1g-dev flex
You will get a question with (yes or no) in terminal....you have to press y then enter
3. Download source code
Code:
mkdir android && cd android
mkdir kernel && cd kernel
mkdir xiaomi && cd xiaomi
git clone https://github.com/rama982/android_kernel_xiaomi_onc.git onc
This will download the source code to /home/android/kernel/xiaomi/onc
You PC will download around 1.2 GB....this may take sometime depending on your internet connection speed
4. Compile kernel
One of greatest thing that @rama982 did was to embed a build script that make our lives way easier while compiling the kernel
You might need to change the kernel directory variable to your own path
Code:
KERNEL_DIR=${HOME}/$(basename $(pwd))
to
Code:
KERNEL_DIR=/home/android/kernel/xiaomi/onc
Once done editing build.sh file...let's compile the kernel
Code:
cd /home/android/kernel/xiaomi/onc
chmod a+x build.sh
./build.sh
chmod command is to make build script excutable
the build script will clone toolchains required to compile the kernel and will also clone Anykernel3 which is very useful to make the final flashable zip file.
Once the build script has done its magic you will get your flashable zip in /home/android/kernel/xiaomi/onc/Anykernel3
I hope i made every step as clear as possible
I am available for any questions
Best Regards

Nice tutorial. I will give a shot when I am free. Thank you.

where is build.sh file ? remove ?

I'll update it soon

Your stock branch working only the wifi when I change the CONFIG_PRONTO_WLAN=y to CONFIG_PRONTO_WLAN=m
Why only working with module?

I guess you are building for Miui...i adjusted my branch for Rom builders to build kernel inline with custom Roms with source built vendor..

build with semaphoreci.sh works perfectly on micode sources, and the special thing is after the build is complete, kernel.zip is sent to the telegram channel itself

Really thank you

[GUIDE] how to build a kernel for S20 FE (snapdragon) may 28, 2022

*hello everyone my name is El_chanz and today I came here to teach you how to compile a kernel for s20fe
Ok guys, I am going to show you how to build a Sammy kernel from my source.
Below is a list of requirements that you must have in order to be successful.
REQUIREMENTS
1. For the best outcome, you need to be on Linux. I dont support VM Box
2. A github account or the like. Its free.
3. Be familiar with terminal commands
4. And have alot of patients
first thing open a terminal on your desktop you must run the following command: git clone https://github.com/Elchanz3/klimbokernel.git
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
this will clone my source to your directory
well after you finish cloning my source to your directory enter on my source
well if you want to configure the kernel with your modifications go to klimbokernel_s20fe/arch/arm64/configs and open the r8q_defconfig as text and make your changes
after finishing your settings go back to /klimbokernel_s20fe
now you are inside the source open the terminal
now run the following command: ./build_kernel.sh ) as root, my script will automatically install the necessary dependencies: gcc clang and All the android dependencies
after you run the script it will start installing the things needed for the build it will ask for permissions to install
you need to say ( y ) to all
after installing everything the script will ask which variant you want to compile the kernel for
, you choose need to choose your device variant
ok after you choose it will compile for your variant you will need to wait, this can take time depending on your cpu in my case it compiles between 25 to 30 minutes
your kernel is already compiled and ready to be flashed!
to find the kernel zip file go to anykernel3
all done
remembering that my script runs clang 10 if you want the latest stable version of clang you will need to download
download link: https://android.googlesource.com/pl...3febb26cbd05d9a1e44f089190ac892f72e684.tar.gz
after you download this you will need to extract to /home
then open the following path: /home/chanz/clang-14.0.7/clang-r445002/bin
in my case i renamed this to clang 14 but enter linux-64 and do this path
copy this path and go back to kernel source and edit the build_kernel.sh script
edit the KERNEL_LLVM_BIN=clang-12 line to
KERNEL_LLVM_BIN=/home/chanz/clang-14.0.7/clang-r445002/bin/clang
remember put your clang path here, i used my only path as an example
after that save the script and run it in the source terminal (./build_kernel.sh)
well after that the kernel will be compiled automatically
and we finally ended up here
I hope I helped you
if I helped you don't forget to leave a like XD
goodbye until next time!

Good guide

Hi,
for compiling exynos kernel the guide it's fails.
Please update also exynos.
Thank you

Hello! I'm trying to understand the process of building the kernel from source according to the instructions but I get an error. Can you suggest what am I doing wrong?

Subsequently, when building the kernel, I encountered a problem, can you tell me how to fix the errors?

did you follow the steps correctly?

I am planning to build roms for this device. Can you help me with some things?
1) Does this device have a device tree?
2) If not, I will try to build one but this will be my first time so I will appreciate any help

No worries man. I'm just glad you took the time to reply.

Greetings to all !!! I finally learned how to successfully compile the kernel for my device .. but later I ran into a problem. My software cannot raise the access point with the given software (SSID and password). Something intuitively tells me that when compiling the kernel, I did not include any of the settings .. Can someone tell me what the problem is ???
