(Q) Kernel building 101

I am a native Linux user and have configured/compiled *nix kernels dozen of times.
I was wondering about the HTC kernel and how it my differ from let's say a gentoo build?
I have found little to none on kernel programing, I must be blind. Can someone direct me to some tutorials? I'm not trying to re-program, I'm trying to re compile the Droid kernel and see what options and what it could take to ultimately port the Linux aircrack-ng suite over to Droid.

Hey. I'm not sure about the kernel compiling part, but bump for that stuff. The aircrack part I've heard that the encryption for aircrack en mass is incredibly slow on arm procs. However if you find out some info, I'd be right there with you

Oh and yes, I'm part of the Gentoo clan also. So I'm no stranger to compiling and troubleshooting kernels. Haha or any number of other related problems

You just need to grab an arm cross compiler and build with that. You can use the one provided by Google or a number of others. Other than that its pretty much the same as building a kernel for your desktop. I'll post some more detailed instructions later if you need them when I have access to a computer.

Im running gentoo, backtrack and kubuntu. I really enjoyed installing gentoo, really helped learning more of the innerworkings of Linux .
That would be great if you could suggest some material chad. I'm currently running your latest kernel and have no problems. Thanks for all of the releases, I bet its been a long road.

Okay, kernel building 101:
You need to grab a few packages first. If you're running (k)ubuntu/debian you need:
Code:
32bit and 64bit systems:
git-core gnupg sun-java6-jdk flex bison gperf libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev
64bit only (in addition to the above):
ia32-libs lib32z1-dev lib32ncurses5-dev gcc-multilib g++-multilib
Then you need to grab a cross compiler. You can use the one provided by google:
http://dl.google.com/android/ndk/android-ndk-r5b-linux-x86.tar.bz2
or grab one of numerous others (codesourcery, I believe there may be one in the ubuntu repos, etc etc.)
extract that somewhere.
Grab the kernel source of your liking (from developer.htc.com or from someones github).
Go into the kernel working directory and then:
Code:
export CROSS_COMPILE=wherever_you_extracted_the_ndk/android-ndk-r5b/toolchains/arm-eabi-4.4.0/prebuilt/linux-x86/bin/arm-eabi-
make ARCH=arm whatever_defconfig (you need to find the name of the defconfig you want to use, they're located in arch/arm/configs)
then do as you please to the config / source etc. If you want to use menuconfig make sure you do:
Code:
make ARCH=arm menuconfig
when you're ready to compile:
Code:
make ARCH=arm -whatever_flags_you_want_to_set
then you have to package up the kernel / modules how you want and flash them. I use koush's AnyKernel as do most others. You can just grab a random zipped kernel on here and replace the zImage and modules with those from the kernel you just built and flash.
when its done building the zImage is located at:
arch/arm/boot/zImage
The modules are located all over depending on which ones you built. I generally only include the wifi module and one for cifs. They'll be at
drivers/net/wireless/bcm4329/bcm4329.ko
and
fs/cifs/cifs.ko
Good luck have fun!

Thank you

Amazingly, you have me compiling a kernel in about 10 minutes of work, vs the couple hours I've spent trying to get it before. Granted last time I was compiling an arm toolchain from scratch, which was a little more bothersome lol

Hahaha. For sure. Getting everything set up to build a toolchain is a pretty big PITA. Absolutely everything and anything causes build errors.

[GUIDE]Compile from CM7 Source (Kanged) Ubuntu 11.10 - 12/31/2011

*WARNING! I Am Not Responsible For Anything That Happens To Your Device or Computer*​Here is another Gift from the DARKSIDE Dev Team:
Compiling CM from Source
Thank you to Sparksco for building a great base tutorial that I used help build this.
Original Thread Found Here
Updated info for non-debian based systems thanks to Vicodan:
If you want to use this on fedora or non-debian based systems you will need to replace every command that says apt-get to yum. Thanks to Vicodan for pointing this out.​
*Note: Not currently working on Tmobile Hercules, for learning purposes only until source is out for our device​
If you can add anything let me know and I will add to this or edit the tutorial, 2nd post will be for building from Google Source AOSP.​
Hardware Requirements:
- A minimum dual core pc, the more ram the better
- A working wifi connection or network connection
- Linux Operating System. Either 32-bit or 64-bit will work
NOTE: 64-bit will run faster and you need 64bit to build Android 2.3 +
You also need full access to CM source but CM is hording those
Black Bold Print = Instructions
Red Bold Print = Terminal Code
Italic Font = Misc. Details
Optional Recommended Software:
Many of these can be found in the software center using the search box
If you find multiple versions it's ok to install them all, unless it says
otherwise
Python
Open the terminal application and type
Code:
[COLOR="red"][B]$ sudo apt-get install python[/B][/COLOR]
awk and gawk
7zip
RAR
Code:
[COLOR="red"][B]$ sudo apt-get install rar[/B][/COLOR]
Step 1 java:
Setting up java is one of the most important step to getting your pc prepared for a build environment. Truly this step is whatever is going to work best on your system, I do it this way and you can try it whichever way you want. Take my advise or not.
NOTE: On Ubuntu 11.10, and variants, you need to enable the
parter repository to install sun-java6-jdk:
Code:
[COLOR="red"][B]$ sudo add-apt-repository "deb http://archive.canonical.com/ maverick partner"
$ sudo apt-get update
$ sudo apt-get install openjdk-6-jdk[/B][/COLOR]
then do
Code:
[COLOR="red"][B]$ sudo apt-get install -y git-core gnupg flex bison gperf libsdl1.2-dev libesd0-dev libwxgtk2.6-dev squashfs-tools build-essential zip curl libncurses5-dev zlib1g-dev pngcrush schedtool g++-multilib lib32z1-dev lib32ncurses5-dev lib32readline5-dev gcc-4.3-multilib g++-4.3-multilib
$ java -version[/B][/COLOR]
The correct version is:
java -version
java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03)
Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02, mixed mode)
You must have a 1.6.x to compile on the gingerbread branch of cyanogenmod. If you have the correct
Step 2 - Install git
Code:
[COLOR="Red"][B]$ sudo apt-get install git[/B][/COLOR]
Step 3 - Prepare the Build Environment
NOTE: You only need to do these steps the first time you build.
If you previously prepared your build environment, skip to Copy
proprietary files.
3a - Install the ADB
To let Samsung Galaxy S2 be recognised by the debugger add these lines to 92-samsung.rules in /etc/udev/rules.d
Code:
[COLOR="red"][B]$ sudo gedit 92-samsung.rules in /etc/udev/rules.d[/B][/COLOR]
paste
Code:
[B]SUBSYSTEMS=="usb", ATTRS{idVendor}=="04e8",
ATTRS{idProduct}=="6640", MODE="0660", OWNER="root",
GROUP="androiddev", SYMLINK+="android%n"
SUBSYSTEM=="usb", SYSFS{idVendor}=="04e8", MODE="0666"[/B]
save and exit
$ sudo gedit /etc/udev/rules.d/51-android.rules
paste
Code:
[B]SUBSYSTEM=="usb", ATTRS{idVendor}=="0bb4", MODE="0666"
SUBSYSTEM=="usb", ATTRS{idVendor}=="0502", MODE="0666"
SUBSYSTEM=="usb", ATTRS{idVendor}=="12d1", MODE="0666"
SUBSYSTEM=="usb", ATTRS{idVendor}=="1004", MODE="0666"
SUBSYSTEM=="usb", ATTRS{idVendor}=="22b8", MODE="0666"
SUBSYSTEM=="usb", ATTRS{idVendor}=="04e8", MODE="0666"
SUBSYSTEM=="usb", ATTRS{idVendor}=="0fce", MODE="0666"
SUBSYSTEM=="usb", ATTRS{idVendor}=="0489", MODE="0666"
SUBSYSTEM==”usb”, ATTRS{idVendor}==”18d1″, SYMLINK+=”android_adb”, MODE=”0666″
SUBSYSTEM=="usb", ATTRS{idVendor}=="04e8", MODE="0666", GROUP="plugdev"[/B]
save and exit
Code:
[COLOR="red"][B]$ sudo gedit .bashrc[/B][/COLOR]
paste at the top
Code:
[B]#AndroidDev PATH
export PATH=${PATH}:~/androidsdk/tools
export PATH=${PATH}:~/androidsdk/platform-tools[/B]
save and exit
Now to Install the SDK, be prepared this takes some time:
Go to Android Developers SDK Download Found Here - Link
or
Download directly from This Link - Download Link
Once done extract the contents to your home folder, then rename it to androidsdk.
Once extracted and renamed go to /androidsdk/tools and double click the file android and click run in terminal.
Android SDK updater will pop up, select the option New and start the upgrade. Now wait. When finished do new one more time to make sure you got everything, once done close SDK window and terminal window.
3b - Install the Build Packages
Install using the package manager of your choice:
For 32-bit & 64-bit systems:
Code:
[COLOR="red"][B]$ sudo apt-get install git-core gnupg flex bison gperf libsdl1.2-dev libesd0-dev libwxgtk2.6-dev squashfs-tools build-essential zip curl libncurses5-dev zlib1g-dev sun-java6-jdk pngcrush schedtool[/B][/COLOR]
For 64-bit only systems:
Code:
[COLOR="red"][B]$ sudo apt-get install g++-multilib lib32z1-dev lib32ncurses5-dev lib32readline-gplv2-dev gcc-multilib g++-multilib[/B][/COLOR]
4a - Create the Directories
You will need to set up some directories in your build environment.
To create them:
Code:
[COLOR="red"][B]$ mkdir -p ~/bin
$ mkdir -p ~/android/system[/B][/COLOR]
4b - Install the Repository
Enter the following to download make executable the "repo" binary:
Code:
[COLOR="red"][B]$ curl https://raw.github.com/android/tools_repo/master/repo > ~/bin/repo
$ chmod a+x ~/bin/repo[/B][/COLOR]
NOTE: You may need to reboot for these changes to take effect.
Now enter the following to initialize the repository, repo sync will take a long time so sit back and watch the code on terminal scroll, dont touch it, toss in Star Wars Saga or Lord of the Rings Trilogy and watch from start to finish and it might be done:
Code:
[COLOR="red"][B]$ cd ~/android/system/
$ repo init -u git://github.com/CyanogenMod/android.git -b gingerbread --repo-url=git://github.com/android/tools_repo.git
$ repo sync[/B][/COLOR]
4c - Copy proprietary files
NOTE: This only needs done the first time you build. If you have
already done these steps, you may skip to Download RomManager.
You will need to have a speedy with a working copy of CyanogenMod
install and ADB working on the computer. This script will copy the
proprietary files from the device.
Connect the device to the computer and ensure that ADB is working
properly.[/B]
Code:
[COLOR="red"][B]$ cd ~/android/system/device/samsung/(DEVICE NAME)
./extract-files.sh[/B][/COLOR]
4d - Download RomManager
NOTE: This only needs to be done when an update to
RomManager is released. If you are-up-to date, you may skip to Building
CyanogenMod. Download RomManager which is needed by the build:
Code:
[COLOR="red"][B]$ ~/android/system/vendor/cyanogen/get-rommanager[/B][/COLOR]
5a - Building CyanogenMod
Check for updates
First, check for updates in the source:
Code:
[COLOR="red"][B]$ cd ~/android/system/
$ repo sync
$ cp build/core/root.mk -f Makefile[/B][/COLOR]
5b - Set up your Compiler
This is optional but helpful for kernel compiling
There are a lot of things that need to be added to the .bashrc to let your
pc know about which type of compiler you want to use. The best way is
to use the one provided in the CM7 work tree.
Code:
[COLOR="red"][B]#Android
export ARCH=arm
export CCOMPILE=$CROSS_COMPILE
export PATH=$PATH:~/android/system/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin[/B][/COLOR]
6 - Configure Build & Compile
Now, the environment must be configured to build and the ROM
compiled, from code, for the GalaxyS2.
Code:
[COLOR="red"][B]$ . build/envsetup.sh && brunch (DEVICE NAME)[/B][/COLOR]
7 - Install
Copy your .zip file from
~/android/system/out/target/product/galaxys2att/update.cm-XXXXX-
signed.zip to the root of the SD card.
Optional: Download Google Apps for CyanogenMod 7 and place it on the
root of the SD card.
Flash both of these .zip files from recovery.

Blah, keep misreading things, don't always assume on that, someone I know has issues with OpenJDK and the programs he's written in SUN's. On another note you also need to run apt-get update after adding the repo.

Not trying to be an ass, but who knows what could happen on someone else's system. You say in the post that you need to install the SUN one, then install the OpenJDK one. Which ever one works for you the best, I'd just edit the steps to make sure you don't contradict yourself.
After "$ sudo add-apt-repository "deb http://archive.canonical.com/ maverick partner"" you need to run "sudo apt-get update" then install the package, else apt won't know the package is available since the source list was edited without a refresh.

The ATT version and the T-Mobile Version are exact mirror images, that just pulls the proprietary files from the phone which are necessary for you to build a rom and Yes I just did it. It works. I was looking in the Cyanogen Source tree and there were three or four Galaxys2's. And I decided to go with the ATT version because I thought it was the closest. Non of them said T-Mobile or Hercules. I am not at my house or I would name the GalaxyS2's that are under the device/samsung/ folder. I will do it when I get home.

Ok so which one of the 4 would you use?

If you want to have a working T-Mobile Galaxy S2 I advise you not to follow this guide.
Source for MSM_8660 devices (read: our phones) is not open source and you can not build it yourself. An official member of the CyanogenMod team can build it as they have access to these sources.
This guide may work for the AT&T Galaxy S2 (not the Skyrocket), but it will sure as hell not work for this phone.
Also, it looks like you just took the tutorial from the CM wiki and formatted it for the forums and mixed in some of the tutorial from s.android.com... what have you actually added to this?
Good day, sir.

I didnt pull anything from the CM wiki nor s.android.com I pulled it from Sparksco thread, which I stated, then I added the code for Samsung rules.d along with adding in how to get the proper java, because sparksco's way wasnt working for me. Right it will work for ATT, but it gives the user a good start on if they want to start building first for other phones and 2nd to try to build for our phone.
Why does everybody have an issue with people learning how to compile from source. Let them learn and do it themselves, the more people we get to learn to build Roms the better the thread will be. I have no idea why you are hating but if this is how this thread got its bad name then I know exactly why. All you can do with somebody either trying to help or looking for help is beat them down, instead of just helping them. I said in my OP that if things need to be edited then let me know. This hostility is uncalled for. Especially from a fellow Developer, that is no way a developer should act. Is that how your mother brought you up to act, I think not. Wow this thread was starting to look good again and turn around then the wolves come out to hate again. I guess nap time was over.

Despite what people are saying in the thread , I appreciate the effort you made Royal. Although I'm not building cm7, I'm intending to experiment on gb and ics AOSP to learn on . This does help some
I also think people don't know that TeamDarkside has a working cm7 port released either ..... and that you are part of it :-\

How to compile the GS3 kernel from source

Prerequisites:
A (preferably 64 bit) BSD/Linux distro, I use LMDE but most prefer Ubuntu
The setup (only have to do once)
1. Install some binaries for compiling android. Not all of these are needed but get them all to be safe...
"sudo apt-get install git-core gnupg flex bison gperf libsdl1.2-dev libesd0-dev libwxgtk2.6-dev squashfs-tools build-essential zip curl libncurses5-dev zlib1g-dev sun-java6-jdk pngcrush schedtool
g++-multilib lib32z1-dev lib32ncurses5-dev lib32readline5-dev gcc-4.3-multilib g++-4.3 multilib"
2. Clone the prebuilt toolchains
"git clone git://github.com/cyanogenmod/android_prebuilt.git ~/prebuilt/"
3. Clone the GS3 kernel source
"git clone git://github.com/EpicCM/SPH-L710_NA_Kernel.git ~/GS3Kernel"
Compiling
1. Enter your kernel directory
"cd ~/GS3Kernel"
2. Add the toolchain to path
"export PATH=$PATH:/home/{your username}/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin/"
3. Clean the kernel source
"make ARCH=arm clean"
4. Set the config for the Sprint GS3
"make ARCH=arm m2_spr_defconfig"
5. Compile the kernel
"make -j4 ARCH=arm CROSS_COMPILE=arm-eabi-"

Would you know a working method to modify the kernel? Say to add init.d, boot animation and root? I found a guide on here from another section. It appeared to have worked just fine, but when someone flashed one of their own from the guide it bricked their device :s

Dude I don't think its possible to make a kernel yet since the device source is incomplete and the kernel source won't give you a complete boot image. Maybe I am wrong though, what device source did you use? And did it compile as a zimage? I'm pretty sure you would either need a pre existing boot.img or to build with the device source as well, but that doesn't have the right files yet.

I will try this with my T-Mo version when I get home. With the tmo kernel of course

while this is a decent guide to get you up and running, its not all that is needed to make a hopefully booting kernel.
1) https://github.com/Shabbypenguin/SPH-L710_Ramdisk enjoy
2) mkbootimg --cmdline "console=null androidboot.hardware=qcom user_debug=31" --kernel /zImage --ramdisk /ramdisk.gz --base 0x80200000 --ramdiskaddr 0x81500000 -o /Boot.img
that should be the command to pack the zimage with the ramdisk.gz and end up with a boot.img format. i know a lot of the samsung devs are prolly more used to the traditional kernel setup. that command line and base address i have yet to test, but if i find out its wrong ill come back and edit it for the purposes of knowledge
edit: also here is a fancy little kernel script i used, edit the spots you need to to make it work etc. youll notice CROSS_COMPILE isnt there, its because i edited the makefile to reflect my toolchain

the anykernel updater is fine, however it unpacks someones current kernel takes their ramdisk and puts it in yours, ergo if you enable bootanimations and init.d by using that on a stock user you will lose all that.

Where do you place the modules with this process? I dont see them listed anywhere in the ramdisk? Also if you decompile a stock kernel the modules dont show up anywhere in the ramdisk? Im used to the old samsung way zImage style with initramfs.... Im confused can someone unconfuse me?

[Dev Tutorial] Kernel compiling for PrimoC/U

Hello everyone. Today I decided I wanted to give back to the One V community with a tutorial on building a kernel. This is not specific to the Primoc/u and contains the directions for both. The source even includes both! So lets hit the ground running.
Note: for the most up to date instructions visit here
Now youll need to have access to sudo to get the packages needed. here are the commands to get packages
Ubuntu 10.04-11.10:
Code:
sudo apt-get update; 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 gcc
Ubuntu 12.04
Code:
sudo apt-get update; sudo apt-get install git-core gnupg flex bison gperf build-essential zip curl libc6-dev libncurses5-dev:i386 x11proto-core-dev libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-glx:i386 libgl1-mesa-dev g++-multilib mingw32 openjdk-6-jdk tofrodos python-markdown libxml2-utils xsltproc zlib1g-dev:i386 gcc
Now, to get the source run these commands
Code:
cd ~/
mkdir kernel
cd kernel
git clone git://github.com/teamblueridge/MSM7X30_KERNEL.git onev_kernel
cd onev_kernel
first you are changing to your home directory. Next your making a folder for kernels, and then pulling the source from github. This source is modified and maintained by me, so I know it stays working. Finally your changing into the kernels directory. Now how do we build this thing you ask. Well we have to do some more prep work. Lets start that prep work
run these commands
Code:
cd ~/
mkdir toolchains
cd toolchains
#this takes some time
git clone https://android.googlesource.com/platform/prebuilt android_prebuilt
cd ~/kernel/onev_kernel
Now we select our branch
for ics run
Code:
git checkout ics
For jb
Code:
git checkout jb-hack
Now were ready to build. Basically your grabbing the android prebuilts which includes the needed toolchain in the steps before.
Now heres the fun codes
Okay below, i have a -jX in the command. This is the number of parallell builds. This will be the number of your CPU's plus one. If you have no clue how many cpus you have run this code below and add one
Code:
grep -c processor /proc/cpuinfo
To make CDMA
Code:
make ARCH=arm primoc_defconfig
make -jX ARCH=arm CROSS_COMPILE="~/toolchains/android_prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin/arm-eabi-"
To make GSM
Code:
make ARCH=arm primou_defconfig
make -jX ARCH=arm CROSS_COMPILE="~/toolchains/android_prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin/arm-eabi-"
So whats going on here you ask now? your using gnu make to build a kernel! arm is the architecture, CROSS_COMPILE is the toolchain we downloaded and -j`grep -c processor /proc/cpuinfo` will find the number of cpu cores you have and adjust the speed for your system!
So now your kernel is created and you want the kernel image to stick in your boot.img. Well its always located at ~/kernel/onev_kernel/arch/arm/boot/zImage any modules you selected are listed at the end of the build
If you were wondering, you can also modify the .config with this command
Primoc
Code:
make mrproper"
make ARCH=arm primoc_defconfig
make menuconfig
Primou
Code:
make mrproper
make ARCH=arm primou_defconfig
make menuconfig
Want the easy way out? Try this script
https://github.com/simonsimons34/kernel-building-script

reserverd for future use

Perfect!! Now I can remember how to do it when I don't want to waste Jenkins!

Nice one! :good:

At the beginning, why not just have them export "~/toolchains/android_prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin/arm-eabi-" as CROSS_COMPILE? I am sure there is a legit reason why, so I am not being a stink head. I suppose that unless the user added it to .bash_profile, they'd forget to do the "export" command each time...

You actually answered your own question there this is meant to be easy to follow and not go into too much depth where users unfamiliar to linux cant follow. Its trying to get people enjoying the ease of linux and not be too easily scared off. Also, forgetting to export was the exact reason I didn't have an export. This hurts nothing, afterall

got an error. followed the guide step by step, Ill fix it myself im just letting you know.

ok first awsome of u to share it with us ok ive ran the commands with ubuntu and ive done the whole process and when it is finished and the kernel is done what do we have to do how to we convert it to a image file and get it on the device im sure this is a stupid question and a waist of ur time i appoligize for me being a noob

Mods/admins recently had a discussion on where guides/tutorials should go and it was decided that the General section is the place for them. Moved there.

No no this is a tutorial. Its meant to allow people interested to be able to learn and do it. The next big thing may come from someone that gave up. Everyone needs help along the way. Once you get the kernel compiled, you can download android kitchen from here. I don't have a link, Google will suffice. So take that open menu with ./menu now go yo 0>12>w>x>0>x and go to the boot extracted folder. Note you must set up kitchen from a sick kernel zip that I have released. Now once in this directory delete the zImage there and replace with the one you compiled. Now go to ./menu 0>12>b>x>0>x and in the Working directory your new kernel is ready to be sent to your phone! All you have to do after that is when the ROM is booted run
adb remount
adb push /path/to/bcmdhd.ko /system/lib/modules/bcmdhd.ko
Enjoy

[Kernel Base][3.4.55][Dev]Bare Repositories of TW/AOSP Kernel (4.3 Sammy Sources!)

Up-to-Date Bare Repositories for TW/AOSP 4.2.2 Kernel​samsung-kernel-jfltexx​
Short Info:
I've made this repository to have a central place for everyone to fork their kernel base from. The advantage of this repo is that it is always up-to-date (as in the latest linux kernel version). Imagine the difference from starting at a 3.4.0 kernel base and 3.4.52 kernel base, there are thousands of new patches in that patch range. :good:
Repository Url:
Code:
https://github.com/broodplank/samsung-kernel-jfltexx
Repository Info:
Name: samsung-kernel-jfltexx
Description: Bare repositories for jfltexx (i9505)
Branches: tw-4.2.2 and aosp-4.2.2 (aosp 4.3 coming when 4.3 kernel sources are released)
tw-4.2.2 = Stock i9505 TouchWiz Kernel from Samsung sources patched until latest linux kernel version
aosp-4.2.2 = i9505g Google Edition Kernel (for AOSP 4.2.2 Google Edition and TouchWiz 4.2.2) (for i9505)
Getting the sources:
If you want to compile the kernel directly without much changes it's advised to clone it:
Code:
git clone [url]https://github.com/broodplank/samsung-kernel-jfltexx[/url] -b branchname
If you want to make your own kernel it's advised to fork the kernel:
- Login at github
- Go to https://github.com/broodplank/samsung-kernel-jfltexx
- Click Fork at the right top of the page

Usage Info:
Initializing first config:
Code:
make VARIANT_DEFCONFIG=jf_eur_defconfig jf_defconfig
Configuration:
Easiest variant (QT based GUI, needs libqt4-dev libqt4-core and libqt4-gui)
Code:
make xconfig
Default variant:
Code:
make menuconfig
Other less popular variants:
(GTK based, doesn't need any special packages)
Code:
make gconfig
(Ncurses based, needs libncurses5, libncurses5-dev and libncursesw5)\
Code:
make nconfig
Building Kernel:
Code:
export ARCH=arm
export CROSS_COMPILE=/path/to/toolchain/bin/arm-eabi-
make -jx (where x is the amount of cpu cores + 1)
Toolchains:
Toolchains that are suited for building the sources are:
arm-eabi-4.6

Building boot.img:
Code:
./build_bootimg
(Choose the rom type you will be using and it will be created in build/output)
Flashing boot.img and modules:
Code:
./flash_bootimg
(This is a process that pushes boot.img to your phone and then to the kernel partition, after that you can choose whether to push modules or not, and finally you can choose to wipe dalvik-cache or not and it will reboot.
Updating Info:
If you have forked the repository do this to fetch the updates from this repository:
First add it to the remote:
Code:
git remote add bare [url]https://github.com/broodplank/samsung-kernel-jfltexx[/url]
git fetch bare
Then search for the commit(s) that you want to merge

Thanks, I just forked it.
I'm a noob at this but am learning fast. I've modified and compiled the 3.0.31 kernel for the 9210T but I'd like to now try 3.4. Appears none of the celox changes for board_msm8x60.c source came across from 3.0 to 3.4 so I think I've got my work cut out for me.

This guide is not working for me.
If I follow your guide the resulting kernel boots, but I have no sound and no 3G (PIN pad doesn't show up).
I'm on MF8 stock ROM. Yours, Ausdims or my own (based on Samsung Update 2 sources) work fine.
This is what I did:
$ git clone https://github.com/broodplank/samsung-kernel-jfltexx -b tw-4.2.2
$ make VARIANT_DEFCONFIG=jf_eur_defconfig jf_defconfig
$ export ARCH=arm
$ export CROSS_COMPILE=/path/to/toolchain/bin/arm-eabi-
$ make xconfig (no changes!)
$ make -j3
$ ./build_bootimg && ./flash_bootimg (selected 1 for TW)
What am I doing wrong?

Tonight Ill do a little research on this and tell you the solution.

I remember when I started to make my first kernel, I had similar problems with the Samsung sources.
Wanam gave me his jf_defconfig file and it worked. He said that the config file by Samsung is crap. But I forgot to ask for details.
If I use my config file on your sources, it results in a bootloop, whereas they work fine with Samsung update 2 sources.
Does that make sense?

Still figuring out, why i cant even successfully compile the sources. With ktoonse sources it works.
But i'm still a beginner. Will see about that xP

I hate it -.- xD
Now it worked. And I do not know why... As I am pretty new to this, as already said, - could this be the problem? :
I think I made this:
$ make VARIANT_DEFCONFIG=jf_eur_defconfig jf_defconfig
$ make xconfig
$ export ARCH=arm
$ export CROSS_COMPILE=/path/to/toolchain/bin/arm-eabi-
Click to expand...

instead of:
$ make VARIANT_DEFCONFIG=jf_eur_defconfig jf_defconfig
$ export ARCH=arm
$ export CROSS_COMPILE=/path/to/toolchain/bin/arm-eabi-
$ make xconfig
Click to expand...
Click to collapse
So I used xconfig before setting ARCH and CROSS_COMPILE.
Could that be the problem?
Atm i can not paste the error. The first one had something to do with a buffersize. Could "fix" that by setting "CONFIG_FRAME_WARN=1024" higher. Because it said it was 1032.
Second error was something like "‘ret’ may be used uninitialized in this function [-Wuninitialized]".
---------- Post added at 08:08 PM ---------- Previous post was at 07:32 PM ----------
Will add a new post for this, if it's okay.
And i hope it's okay to ask in here
So, first, as wrote in my previous post the compiling worked.
Now, i did the following:
1. Changed in the config: "kernel compression mode -> LZO
2. Removed "Optimize for size"
3. And changed the flag in the makefile to O3.
kernel/workqueue.c: In function 'freeze_workqueues_begin':
kernel/workqueue.c:483:11: warning: array subscript is above array bounds [-Warray-bounds]
error, forbidden warning: workqueue.c:483
make[1]: *** [kernel/workqueue.o] Error 1
make[1]: *** Waiting for unfinished jobs....
While writing this I reset "Optimize for size" and restart compiling. Now it does seem to work.
So i guess there is a problem with the flag. Where is the right place of the flag?

If you want to use O2 or O3, it requires some modification of config and make files.
The build boot.img script worked for me right away.

It will work if you have the right toolchain, I use this one:
http://www.mediafire.com/download/i...linaro_4.7.4-2013.07-build_2013_07_12.tar.bz2
