VERSION = 1.3.0
# Irrlicht Engine 1.3
# Makefile for Linux, created by N.Gebhardt.
# 
# To use, just run:
#
# make
#
# This will compile Irrlicht, create a static lib (libIrrlicht.a), and copy it
# into the subdirectory lib/Linux. That's all.
#
# If you want Irrlicht to be compiled as shared lib (libIrrlicht.so.versionnumber), then run:
#
# make sharedlib
# make install
#
# Please note that Irrlicht as shared lib is just experimental and  
# probably not tested.
#
