[HOW TO]Building Kernel Source For Any Device

Hello All. I have received several requests for how to build a kernel from source so I figured I would make a guide for anyone looking.
WARNING: I CANNOT BE HELD RESPONSIBLE FOR ANY DAMAGE YOU CAUSE TO YOUR PHONE, PERSONAL RELATIONSHIPS, LIFE, OR CAR. YOU HAVE ALREADY ROOTED YOUR DEVICE SINCE YOU ARE READING THIS SO YOU KNOW IT VOIDS YOUR WARRANTY.
Now that thats over. I will walk you through how to set up a kernel building environment and walk you through building a kernel.
I.) Requirements
1.)You will need a computer. Just about any computer running linux will work, even a Virtual Machine. I will be using Ubuntu Oneiric, Server Edition for my guide. (Most commands are the same across Ubuntu Editions as well as Linux in general.)
2.)Internet Access- the faster the better
3.)Knowledge of the android kernel and what does what.
4.)The Master Branch from Google as well as the source for your device.
5.)ALOT of time.
6.)Common Sense
II.) Installing The Necessary Tools
1.)First we must download the neccesary tools.
To install java, you need to know which version of android you will be developing for.
Froyo and Lower:
Code:
$ sudo add-apt-repository "deb http://archive.ubuntu.com/ubuntu hardy main multiverse"
$ sudo add-apt-repository "deb http://archive.ubuntu.com/ubuntu hardy-updates main multiverse"
$ sudo apt-get update
$ sudo apt-get install sun-java5-jdk
Gingerbread and Newer:
Code:
$ sudo add-apt-repository "deb http://archive.canonical.com/ lucid partner"
$ sudo apt-get update
$ sudo apt-get install sun-java6-jdk
2.)Next we willl download the tools needed(You need to know if you are on a 64 bit system or 32 bit.)
For 64 bit:
Code:
$ sudo apt-get install git-core gnupg flex bison gperf build-essential zip curl zlib1g-dev libc6-dev lib32ncurses5-dev ia32-libs x11proto-core-dev libx11-dev lib32readline5-dev lib32z-dev libgl1-mesa-dev g++-multilib mingw32 tofrodos python-markdown libxml2-utils xsltproc
Also you must link one thing based on your Ubuntu Version:
For 10.10:
Code:
$ sudo ln -s /usr/lib32/mesa/libGL.so.1 /usr/lib32/mesa/libGL.so
For 11.10:
Code:
$ sudo ln -s /usr/lib/i386-linux-gnu/libX11.so.6 /usr/lib/i386-linux-gnu/libX11.so
For 32 bit:
Code:
$ sudo apt-get install git-core gnupg flex bison gperf build-essential zip curl zlib1g-dev libc6-dev libncurses5-dev x11proto-core-dev libx11-dev libreadline6-dev libgl1-mesa-dev tofrodos python-markdown libxml2-utils xsltproc
No linking is necessary.
NOTE: You can set up CCache on either setup. However, you will not need it necessarily due to the source is not that big compared to building a rom and therefore will not take as long.http://dnssearch.rr.com/index.php?origURL=http://www.goog.gl/&r=
III.) Downloading The Source
1.)If you already have an android Directory set up, then skip this step. If not, follow these commands. (NOTE:THIS GUIDE FOLLOWS AS IF YOU USE THIS STEP. BE CAREFUL)
Code:
$ cd $HOME
$ mkdir android
$ cd android
2.)Set up your source directory.
Code:
$ mkdir source
$ cd source
$ mkdir aosp (YOUR DEVICE)_kernel repo
$ cd repo
$ curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ./repo
$ chmod 755 repo
$ export PATH=$PATH:$HOME/android/source/repo/
OR
$ sudo cp repo /usr/bin/repo
$ cd ../aosp
$ mkdir master
$ cd master
3.)You are now ready to grab the source. You will need the master branch. So while in the master directory:
Code:
$ repo init -u https://android.googlesource.com/platform/manifest
THIS WILL TAKE A WHILE SO SIT BACK AND RELAX.
4.)Now you need your specific devices source. So follow those steps accordingly to get the source into the directory for you device kernel @ $HOME/android/source/(YOUR DEVICE)_kernel
You now have all the source you need.
V.) Building The Kernel
1.)Now we will set up the environment for the build.
Code:
$ export ARCH=arm
$ export CROSS_COMPILER=arm-eabi-
$ export CROSS_COMPILE=arm-eabi-
$ export PATH=$PATH:$HOME/android/source/aosp/master/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin/
2.)Now you go into your device's kernel directory.
Code:
$ cd $HOME/android/source/(YOUR DEVICE)_kernel
3.)And begin the configuration.
If you like a gui like menu:
Code:
$ make menuconfig
If you like to answer questions:
Code:
$ make config
4.)Configure your kernel how you want it.
5.)Then, once thats done:
Code:
$ make -j4
This will build the kernel. This can take anywhere from 15 minutes to an hour and a half+.
VI.)Grabbing The Newly Made Kernel
1.) Your kernel will be located at:
Code:
$ $HOME/android/source/(YOUR DEVICE)_kernel/arch/arm/boot/zImage
2.) Your Wireless Module Will depend on your device. For the Ally, it would be:
Code:
$ $HOME/android/source/ally_kernel/drivers/net/wireless/bcm4329/wireless.ko
CONGRATULATIONS!!!
You have built your own kernel.
Now follow http://forum.xda-developers.com/showthread.php?t=748106 to flash it.
Any problems or questions, let me know. Either a PM or I'm almost always in #asus-transformer on IRC.

Gonna try this. Thanks for sharing...

Thanks for working on this. On first look, I think you intended to put a repo sync after the init command here:
3.)You are now ready to grab the source. You will need the master branch. So while in the master directory:
Code:
$ repo init -u https://android.googlesource.com/platform/manifest
THIS WILL TAKE A WHILE SO SIT BACK AND RELAX.

For the device, should it be what our device is named by the company for marketing, etc or is it what is in the build.prop under ro.product.device?? Thanks

@OP: Do I've to make any changes if I were to build from Glitch (SGS) sources for CM7?? Or everything remains the same?

what does (Your device) mean ? its name (example: samsung galaxy ace) or the codename ( example: GT-S5830) ????

[HOWTO] Install Java 7 on Ubuntu 12.04

I'm not sure if this is in the right spot (if not I apologize), but I figure it is because this relates directly to building Android.
When I upgraded to Ubuntu 12.04, all the sudden I couldn't install Java (sha256sum mismatch jdk-7u3-linux-x64.tar.gz), which means I can't do much deving. Well I searched through the interweb and finally found a solution.
First:
Code:
sudo add-apt-repository ppa:eugenesan/java
sudo apt-get update
sudo apt-get install oracle-java7-installer
By now, you have probably gotten an error and the terminal has stated that Java was not installed. No problem.
Second:
Download Java directly from Oracle: http://www.oracle.com/technetwork/java/javase/downloads/jdk-7u3-download-1501626.html
Now, move what you just downloaded to /var/cache/oracle-java7-installer/
Third:
Code:
sudo gedit /var/lib/dpkg/info/oracle-java7-installer.postinst
Now scroll down and find the following:
Code:
echo "Downloading..."
rm -f $FILENAME
WGETRC=wgetrc wget $PARTNER_URL \
|| fp_exit_with_error "download failed"
rm -f wgetrc
echo "Download done."
Now put a # next to each line between "Downloading..." and "Downloading done."
Code:
echo "Downloading..."
#rm -f $FILENAME
#WGETRC=wgetrc wget $PARTNER_URL \
#|| fp_exit_with_error "download failed"
#rm -f wgetrc
echo "Download done."
Save, and go back to your terminal.
Finally, do:
Code:
sudo apt-get install oracle-java7-installer
Java should now install properly.

Make long story short, it didn't execute commands as root? Shame on Java!
Is it working on other distroes debian based like Mint?

AFAIK you need java 6 installed to build android. Not to mention Ubuntu 12.04 is still in the final stages of beta lol.

Well for what I do java 7 is fine with me

THANK YOU SO MUCH. took me a good 2 hours to find this guide. Now I can finally install curl. wtff..

So this is for 64-bit right? That's what I'm using

thanks for the great tutorial.
how bout the fixesif got errors?
if AOKP release new build how can we update it without going all the painful 8gb downloading?
sorry noob here.. i hav linux machine here but seldom use.
so i guess i would like to learn how to build.
am looking forward also into MIUI. do you know how to build one from source ?

Do we really need to download that much???
I don't mind downloading 8 to 12 GB, but, I have frequent power fluctuations at my home... So, is there any way by which I can resume the sync-ing process...
//And, to the main question, I use a 32-bit pc. So is it ok to use? Or do I need a 64 bit one?//*never mind.
P.S: I don't seem to understand why we require 8 - 12 GB for compiling something that would be max 200 mB? Is there any reason for this? or can we reduce the download ammount or something like that?
edit: sorry people... i really didn't read the amd64 architecture requirement...

First of all you require 20GB+ for a Single build and upto 80-100 GBs for a complete set of builds.
Not just 8-12GB

Yes.. but you need to add kernel source, device tree and vendors from Sakinidia's github into manifest.xml

Please don't quote the main thread...

[Heimdall 1.4.2] How to install Heimdall 1.4.2 on Ubuntu 21.10.

Install Heimdall 1.4.2 on Ubuntu 21.10
ABOUT
Heimdall is a cross-platform (runs on Linux, Windows and Mac OSX), open source Odin alternative which uses the same protocol as Odin to interact with a device in download mode, that can be used to flash Android ROMs or Kernels onto Samsung Galaxy S phones.
Ubuntu 21.10 doesn't run qt5 so you have to install the dependencies and make a fake qt5 pkg.
FIRST STEP
open Tilex and install some pkgs.
$ sudo apt install git wget snap unzip
SECOND STEP
Make a fake qt5 default.
$ sudo apt-get update
$ sudo apt-get install equivs
$ cd ~/Downloads
$ cat <<EOF > qt5-default-control
Package: qt5-default
Source: qtbase-opensource-src
Version: 5.99.99+fake-13ubuntu37
Architecture: all
Depends: qtbase5-dev, qtchooser
Suggests: qt5-qmake, qtbase5-dev-tools
Conflicts: qt4-default
Section: libdevel
Priority: optional
Homepage: http://qt-project.org/
Description: Qt 5 development defaults fake package
EOF
$ equivs-build qt5-default-control
$ cd Downloads
$ sudo apt-get install ./qt5-default_5.99.99+fake-13ubuntu37_all.deb
THIRD STEP
Build Heimdall 1.4.2
Download Heimdall from https://gitlab.com/BenjaminDobell/Heimdall/tree/v1.4.2
Unzip and cd into the Heimdall folder.
Install dependencies:
$ sudo apt install qt5-default libgl1-mesa-dev build-essential cmake zlib1g-dev libusb-1.0-0-dev
Create build directory & cd into it:
$ mkdir build
$ cd build
build
$ cmake -DCMAKE_BUILD_TYPE=Release ..
$ make
Heimdall is now compiled and the binary is found in the build/bin folder.
