# 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.
