I'm feeling a bit frustrated (and perhaps stupid... :-]) for not being able to figure out the solution for my HOpenGL compilation problems... I really wonder why cygwin doesn't recognize a simple command like "ghc --version" anymore, and insists that I need to put a ".exe" suffix when trying to run every executable file (i.e., "ghc.exe --version" works). In the ./configure step, I get the message "No Haskell compiler not found" and I'm sure it is not related to the PATH, since it is set correctly. Perhaps this ".exe" problem has something to do with the error... Previous attempts to reinstall cygwin (including removing it from windows98 register and installing it again) were not successful: the ".exe" problem still happens. I followed all steps in http://www.pms.informatik.uni-muenchen.de/mitarbeiter/panne/cygwin/opengl_gl ut.html and previous emails, but I think I'm stuck in something earlier. Any suggestions are highly welcome, as always. Cheers, -- Andre
