# Irrlicht Engine 1.9.0
# Makefile for Linux
#
# 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 switch any settings (like debug/release/static/shared) then first run:
#
# make clean
#
# If you want Irrlicht to be compiled as shared lib (libIrrlicht.so.versionnumber), then run:
#
# make sharedlib
# make install
#
# If you want to compile in release mode run:
#
# make NDEBUG=1
#
# For cross-compilation for Win32 under Linux, just use the win32 targets. You have to set
# at least CXX, CC, and AR to the proper binaries.
#
# For compiling on MinGW you can run it with:
#
# make win32
#
# Or as MinGW by default has CC set to cc - but has no compiler by that name - you might have to do:
# make CC=gcc win32
