This page is for developers who want to customize their build and/or contribute to Lakka.
You will need Linux (we usually build on Debian, Arch or Crux) and the base development packages (base-devel on Arch, build-essential on Debian).
You may also need a local HTTP server to host Lakka packages if you plan to do packaging.
First, clone Lakka:
$ git clone https://github.com/libretro/Lakka-LibreELEC
Lakka is organized by projects, the Generic project targets PCs, while other
projects like RPi targets very specific hardware like the Raspberry Pi.
The full list of projects can be listed like this:
$ ls -l Lakka-LibreELEC/projects
You can now launch make, set the PROJECT/DEVICE and ARCH variables to fit your needs:
$ cd Lakka-LibreELEC $ DISTRO=Lakka PROJECT=RPi DEVICE=RPi ARCH=arm make image # for the Raspberry Pi $ DISTRO=Lakka PROJECT=RPi DEVICE=RPi2 ARCH=arm make image # for the Raspberry Pi2/ Pi3 $ DISTRO=Lakka PROJECT=Generic ARCH=x86_64 make image # for 64 bits PCs $ DISTRO=Lakka PROJECT=Generic ARCH=i386 make image # for 32 bits PCs
Building Lakka the first time takes a lot of time, you can go grab a coffee or two :)
If the build fails, make sure you have at least 10 GB of free space and try to figure out which package is missing, install it, and make again.
You will find the result in Lakka-LibreELEC/target:
$ ls -l target
.system files can be used to upgrade an existing Lakka system.
.img.gz file is the final result, it contains the image that can be flashed to an SD card or a USB pen drive.
Please follow this tutorial to know how to flash Lakka on a drive.
If some time passed and you want to rebuild from newer sources:
$ cd Lakka-LibreELEC $ git pull $ rm -rf target $ DISTRO=Lakka PROJECT=RPi DEVICE=RPi2 ARCH=arm make image
But if you just want to rebuild a particular package, for example a package you are trying to port to Lakka, you can just remove it like this and rebuild.
$ DISTRO=Lakka PROJECT=RPi DEVICE=RPi ARCH=arm scripts/clean yourpackage $ DISTRO=Lakka PROJECT=RPi DEVICE=RPi ARCH=arm scripts/build yourpackage
If you want to rebuild all from scratch, remove the
