# This is the script buildbot.libsdl.org uses to cross-compile SDL2 from
#  x86 Linux to Raspberry Pi.

# The final tarball can be unpacked in the root directory of a RPi,
#  so the SDL2 install lands in /usr/local. Run ldconfig, and then
#  you should be able to build and run SDL2-based software on your
#  Pi. Standard configure scripts should be able to find SDL and
#  build against it, and sdl2-config should work correctly on the
#  actual device.
