GameShell Cross Compiling

GameShell running ruby PlayStation emulator, a C++ SDL2 OpenGL 3.3 project.

crosstool-NG

Simply follow the instructions on how to set up a toolchain from their Documentation page (pages 1-4). If you’re unsure about how to configure crosstool-ng, you can use my configuration available here. Some useful bits:

• GameShell machine name is arm-linux-gnueabihf
• Target OS is linux
• Version is 4.20.8 (based on clockworkOS image 0.3)
• glibc version is 2.24

SDL2

Once you have a cross compile toolchain (building takes a while), you’re ready to cross compile SDL2. Get the source code and run the following for the configuration and installation:

$ ./configure --host=armv7l-unknown-linux-gnueabihf --build=x86_64-linux-gnu --disable-pulseaudio --prefix=/usr
$ make
$ chmod -R +w ~/x-tools/armv7l-unknown-linux-gnueabihf/armv7l-unknown-linux-gnueabihf/sysroot
$ make DESTDIR=~/x-tools/armv7l-unknown-linux-gnueabihf/armv7l-unknown-linux-gnueabihf/sysroot install
$ chmod -R -w ~/x-tools/armv7l-unknown-linux-gnueabihf/armv7l-unknown-linux-gnueabihf/sysroot

Compiling and running

This will only work if you set the GPU driver to Fbturbo.

$ make
$ scp bin/gs-cross-compile cpi@x.x.x.x:~
$ DISPLAY=:0 ./gs-cross-compile
