# MinGW core-glu makefile updated for Mesa 7.0
#
#  Updated : by Heromyth, on 2007-7-21
#  Email   : zxpmyth@yahoo.com.cn
#  Bugs    : 1) All the default settings work fine. But the setting X86=1 can't work. 
#            The others havn't been tested yet.
#            2) The generated DLLs are *not* compatible with the ones built
#            with the other compilers like VC8, especially for GLUT. 
#            3) Although more tests are needed, it can be used individually!

#
#  Available options:
#
#    Environment variables:
#	CFLAGS
#
#	GLIDE		path to Glide3 SDK; used with FX.
#			default = $(TOP)/glide3
#	FX=1		build for 3dfx Glide3. Note that this disables
#			compilation of most WMesa code and requires fxMesa.
#			As a consequence, you'll need the Win32 Glide3
#			library to build any application.
#			default = no
#	ICD=1		build the installable client driver interface
#			(windows opengl driver interface)
#			default = no
#	X86=1		optimize for x86 (if possible, use MMX, SSE, 3DNow).
#			default = no
#
#    Targets:
#	all:		build GL
#	clean:		remove object files
#
