This thread is intended for devs & advanced users only.
Here you can learn how to build CyanogenMod 11.0 for any of the 2011 xperia devices.
I will use 'smultron' as an example device, you should replace the codename with the device you want to build.
For the first time you try to build CM11.0
Follow this guide up to "Initialize the CyanogenMod source repository" step (don't execute this step).
http://wiki.cyanogenmod.org/w/Build_for_smultron
Initialize the CyanogenMod source repository
Enter the following to initialize the repository:
Get the required local manifest
Download the source code
Setup the build environment
Download some commits from CyanogenMod gerrit which are not accepted yet
Get the prebuilts
Setup the build environment & prepare the device-specific code.
Build the ROM (takes long time)
If the build finishes successfully, you will find the build here (change DATE into the date):
~/android/system/out/target/product/smultron/cm-11.0-DATE-UNOFFICIAL-LegacyXperia-smultron.zip
The next times you want to build, you only need to do the following:
Sync the repositories & make sure you are using the latest local_manifest.
Setup the build environment
Download some commits from CyanogenMod gerrit which are not accepted yet
Build the ROM
If the build finishes successfully, you will find the build here (change DATE into the date):
~/android/system/out/target/product/smultron/cm-11.0-DATE-UNOFFICIAL-LegacyXperia-smultron.zip
Steps to build only the kernel:
Sync the repositories.
Setup the environment
Download some commits from CyanogenMod gerrit which are not accepted yet
Build the kernel
If the build finishes successfully, you will find the boot image here:
~/android/system/out/target/product/smultron/boot.img
Some suggestions for faster builds:
* Enable ccache
* Use the fastest hdd on your pc to store the source, build output & ccache
* You can also buy an ssd, if it's not large enough to hold everything, just store the build output & ccache
* mount /tmp on tmpfs (RAM).
The above have greatly improved my dirty build times with removed /out/target from 1h30m to 30m.
Mounting /tmp on tmpfs made the biggest improvement for me.

Initialize the CyanogenMod source repository
Enter the following to initialize the repository:
Code:
cd ~/android/system/
repo init -u git://github.com/CyanogenMod/android.git -b cm-11.0
Get the required local manifest
Code:
mkdir -p ~/android/system/.repo/local_manifests
curl https://raw.githubusercontent.com/LegacyXperia/local_manifests/cm-11.0/semc.xml > ~/android/system/.repo/local_manifests/semc.xml
Download the source code
Code:
repo sync
Setup the build environment
Code:
. build/envsetup.sh
Download some commits from CyanogenMod gerrit which are not accepted yet
Code:
ln -s vendor/extra/updates.sh updates.sh
./updates.sh
Get the prebuilts
Code:
cd ~/android/system/vendor/cm
./get-prebuilts
Setup the build environment & prepare the device-specific code.
Code:
cd ~/android/system
. build/envsetup.sh
breakfast smultron
Build the ROM (takes long time)
Code:
brunch smultron
