Building the System Yourself

If you wish to compile OkcarOS on your own, you should be familiar with Source Control Tools.

Start by fetching the OkcarOS source code locally:

repo init -u https://github.com/okcar-os/android.git -b okcar-1.0 --git-lfs

# This is a lengthy process, The entire source tree is nearly 183GB when fully downloaded.
repo sync

Once the source code is downloaded, you can proceed with compiling OkcarOS following the OkcarOS Build Guide. Compilation is also a time-consuming process; on a computer equipped with an AMD 7950X CPU and 64GB of RAM, it takes approximately 50 minutes. Computers with lower specifications may require several hours or even days for the compilation process.
