Hi! Concerning the Hopen-GL-distribution 1.00 on win2000, latest cygwin, greencard 2.0 The way the target is given in the lib-Makefile doesnt work (at least with my version 2.0(1?) of greencard). I changed the options line in /HOpenGL-1.00/lib/Makefile from GREENCARD_OPTS = -t ghc --name-mangling-scheme=classic to GREENCARD_OPTS = --target ghc --name-mangling-scheme=classic (Also possible with my version of greencard is "-tghc" without a space between) That seems to work. The first file here, GLUT_CBGlobal.gc, runs through the parser which correctly generates the output file GLUT_CBGlobal.hs... but then another error occurs while parsing GLUT_CBWindow.gc: bash-2.05$ make depend /cygdrive/c/ghc/ghc-4.08.2/bin/green-card --target ghc --name-mangling-scheme=cl assic GLUT_CBGlobal.gc -o GLUT_CBGlobal.hs /cygdrive/c/ghc/ghc-4.08.2/bin/green-card --target ghc --name-mangling-scheme=cl assic GLUT_CBWindow.gc -o GLUT_CBWindow.hs "GLUT_CBWindow.gc", proc. spec "", line 285: Parse error: Enum, Bounded) CUnsig nedInt [ % GLUT_JOYSTICK_BUTTON_A, % GLUT_JOYSTICK_BUTTON_B, % GLUT_JOYS make: *** [GLUT_CBWindow.hs] Error 1 I begin wondering if it is actually possible to run HOpenGL on my computer. Hm. The HOpenGL-website says that the library has been heavily tested under Linux AND Windows. But it seems that nobody with my configuration has ever compiled the source package (as far as I know, there are no binary packages available, are they?). Has anybody else tried to compile version 1.00 under win2000/cygwin/greencard2.0(1?)? Does someone know where else I can get the necessary libraries? Thanks very much. Johannes
