[REF]HowTo build CM9 from source - Galaxy S II Android Development

Made the CM wiki a little easier to understand. Most is taken from here:
http://teamhacksung.org/wiki/index.php/CyanogenMod9:GT-I9100:How_to_build
First off you will need Ubuntu 64-bit for this to work (or one of the many ubuntu editions) I recommend the 11.10 version (will work on 10.x also), as it's the newest stable to date. 32-bit won't work. I'm using Xubuntu 64 bit, and it uses the same terminal codes of course.
Install ADB
Install the Android SDK.
NOTE: You do not need to setup the SDK with an ADV etc., just download and install to get the tools (e.g. adb).
Install the Build Packages
Open the terminal in ubuntu and paste the following code snippets:
To add sun-java to repo (works on various ubuntu versions):
Code:
sudo add-apt-repository ppa:ferramroberto/java
sudo apt-get update
To get the needed build packages:
Code:
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
NOTE: gcc-4.3-multilib g++-4.3-multilib is no longer available for Ubuntu 11.04/11.10 64-bit, but should still build without issue. On 11.10 lib32readline5-dev is no longer available, but lib32readline-gplv2-dev is there instead. Just install it with "apt-get install lib32readline-gplv2-dev"
Create the Directories
You will need to set up some directories in your build environment.
To create them paste these in terminal:
Code:
mkdir -p ~/bin
mkdir -p ~/android/system
Install the Repository
Enter the following in terminal to download make executable the "repo" binary:
Code:
curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo
chmod a+x ~/bin/repo
NOTE: You may need to reboot for these changes to take effect.
Now enter the following to initialize the repository:
Code:
cd ~/android/system/
repo init -u git://github.com/CyanogenMod/android.git -b ics
repo sync -j16
Retrieve the galaxys2 repo
Code:
. build/envsetup.sh
brunch cm_galaxys2-userdebug
Copy proprietary files
NOTE: This only needs to be done the first time you build, but it's recommended to redo it when TeamHacksung makes some changes to these in their nightlies (which may occur quite often as of now)..
You will need to have a galaxys2 with the latest nightly of CM9 installed, 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.
Paste this into terminal:
Code:
cd ~/android/system/device/samsung/galaxys2/
./extract-files.sh
NOTE: If some hardware isn't working, like camcorder or FM radio, you will need to find the updated prop blobs.
Get prebuilts
Code:
~/android/system/vendor/cm/get-prebuilts
Building CyanogenMod
First, check for updates in the source:
Paste into terminal:
Code:
cd ~/android/system/
repo sync
Configure Build & Compile
Now, the environment must be configured to build and the ROM compiled, from code, for the galaxys2.
Paste into terminal:
Code:
. build/envsetup.sh && brunch cm_galaxys2-userdebug

Nice guide, just installed ubuntu on my VAIO to do this kind of stuff.
Thnx
On to setting stuff up...

You should consider getting the build script (build.sh) from teamhacksung's github (https://github.com/teamhacksung/buildscripts) and placing it in your android/system folder.
It allows you to use commands like ./build.sh [devicename] [kernel] to build the version of CM7 you want and optionally will compile your own kernel (if you also have the c1 and aries kernel source)
Other commands it supports:
./build.sh clean - to clear the output folders for a clean build
./build.sh prepare - to pull the latest version of Rom Manager
When I build for the SGS2 my sequence of events are always:
repo sync -j16
./build.sh clean
then either:
./build.sh galaxys2 kernel
if kernel code has changed, or
./build.sh galaxys2
if kernel code has not changed.

And after the mentioned build sequence posted above to finalize everything you run the command "build/envsetup.sh && brunch galaxys2" or is that obsolete now ?

If you use the teamhacksung build.sh script then, yes, it is obsolete.

Yes, don't forget the period (.) at the start of the ./build.sh command or it won't run.

I was indeed revering to the build.sh from teamhacksung, thnx.
Got another question, is about: repo sync -j16
What does the -j16 stand for?
I'm aware of the . from ./ , just using linux for the first time to do this kind of stuff, using it a few years now for game/web server and playing some around with it.

First of, this is a re-written guide from the cyanogenmod wiki found here. All credit goes to them!

the link you gave is for sgs1.

To be honest, I don't know. I tried searching the man pages etc but could never find the answer. I use it because it is what is listed on the CM wiki. I have also seen people use -j40 or no setting. They all work.

Yes, the SGS2 wiki page was published today. It does not contain the teamhacksung buildscript details though as that is specific to teamhacksung.

Well just made to build my first Kang using ./build.sh galaxys2 kernel
Just for now i'm testing to see what the difference is with the other building options.
For doing the ADB install part i started with a Howtoforge page about setting up android app builds since it has a good and very detailed part on how to exactly do all the adb installing stuff etc. (which would stand for this part of the turorial *Install ADB*), very newby friendly

I think it's the number of the simultaneous connections that will be opened to the server.

---

Code:
echo "Example: ./build.sh galaxys2 (prebuilt kernel + android)"
echo "Example: ./build.sh galaxys2 kernel (kernel + android)"
As i understand the following from build.sh good. It means that with just the "./build.sh galaxys2" is for stock CM7 kernel as from the source/github after running the sync.
but is "./build.sh galaxys2 kernel (kernel + android)" then for an custom made kernel with tweaks or is this one just for when there is a (bigger) update for the CM7 kernel?

I think you should realse a rom based on cm.

Wow, that is unexpected! And unfortunate! I was going to follow your extensive guide this evening, such a shame you took it away. I did not notice any harassment here, but i'm sorry you felt it. Hope maybe you and the "pros" can sort this out, because i think such a topic would be really valuable here!!!

Please, give us some names, we will know "pros" who don't like to share with others.
Some advanced devs just want to keep there secrets in order to make believe it's too hard for others ...
They would like us to re-invent everything when it exists already. Thats not my vision of linux freedom ...
Or please say us why they insult you ?
