# This is the script buildbot.libsdl.org uses to cross-compile SDL2 from
# amd64 Linux to NaCl.
# 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.
