[HOpenGL] compilation problems

Hi, I've just joined the list and have looked through the backlog of emails but I don't see anyone who's had my problems. Just a few questions... I would like to know what @green_card_comma@ does, as that generated an error in GLUT_Init.gc when I ran make depend. Replacing "@green_card_comma@" with "," seems to resolve it. Also, I have glut3 but code pertaining to glut4.x wasn't commented out? I had a look at configure.in and under " Test GLUT Xlib implementation", I think something like else glut_geq_4_9="-- " glut_geq_4_11="--" glut_geq_4_13="-- " is missing? Then I ran make, and I got the following error: /usr/bin/ghc -syslib lang -split-objs -odir GL_Errors -fglasgow-exts -I/usr/X11R6/include "-#include " -recomp -Wall -O -c GL_Errors.hs -o GL_Errors.o /tmp/ghc6071.hc: In function `s2n5_ret': /tmp/ghc6071.hc:295: `GLU_INCOMPATIBLE_GL_VERSION' undeclared (first use in this function) /tmp/ghc6071.hc:295: (Each undeclared identifier is reported only once /tmp/ghc6071.hc:295: for each function it appears in.) /tmp/ghc6071.hc: In function `GLzuErrors_zdwunmarshallzuError_fast1': /tmp/ghc6071.hc:654: `GLU_INCOMPATIBLE_GL_VERSION' undeclared (first use in this function) make[1]: *** [GL_Errors.o] Error 1 And I'm not sure what I'm missing. Can someone please help me? I tried installing HOpenGL-1.01 with gc-2.03 and ghc-5.02 under debian (woody). thanks, Shuying
