Hi there. I'm new to both Haskell and to HOpenGL. I've been following the instructions on how to do the installation under windows and I've done the following things: . followed all the instructions . copied glut.h from /usr/include/GL to /cygdrive/c/gch/ghc-6.0/include/mingw/GL (found out about this from searching the archives). . then I ran into the problem about "Cannot locate utf8.pm". I've seen some mail about this but no resolution to the issue. I know it isn't directly related to HOpenGL (more a GHC/perl issue) but since the only other occurrence of this I can find was related to HOpenGl I was wondering if anyone else knows what I need to do. System configuration: . P4 Windows XP . cygwin (perl 5.8.1) . greencard 3.00 . ghc 6.00 . HOpenGL 1.04 Here's the output from trying to compile: -- $ make ------------------------------------------------------------------------ Recursively making `all' in lib examples ...
