# This is the script physfs-buildbot.icculus.org uses to cross-compile
#  PhysicsFS from x86 Linux to Raspberry Pi. This script was originally from
#  Simple Directmedia Layer ( https://www.libsdl.org/ ).

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