Sven Thanks for discovering all this. I'm sure Sigbjorn will take it on board when next building an installer for GHC. I suspect the headers are under mingw because GHC will *only* build executables that run on Mingw. Assuming GL comes with mingw headers, I'm sure Sigbjorn will include the Mingw ones, not the Cygwin ones, next time. Sigbjorn: pls yell if you think there is anything unresolved here.

This is where part of my confusion came from. | I suggest changing this on haskell.org/ghc. | | * As an aside, the GHC 5.04.2 installer comes with superfluous compilers | and support libraries for C++, Objective-C and Fortran77. Leaving these | out would reduce the unpacked size of GHC by 6.3MB. :-) | | Some more confusing facts about MinGW and Cygwin: | | * MinGW's headers GL/gl{,u,ext}.h are identical to the ones from Cygwin's | w32api/GL. The GL/glext.h header is lying about the OpenGL version on | WinDoze, pretending it's 1.3. | | * MinGW comes with a GLUT libraries, but not with a corresponding | GL/glut.h header. | | What to do in all this chaos? As the simplest short-term solution I've | packaged the following headers into a ZIP file: | | include/mingw/GL/gl.h (from Cygwin's w32api/GL == MinGW's GL) | include/mingw/GL/glu.h (from Cygwin's w32api/GL == MinGW's GL) | include/mingw/GL/glut.h (from Cygwin's GL) | include/mingw/GL/glext.h (from Cygwin's w32api/GL == MinGW's GL) | | It is available at: | | http://haskell.org/HOpenGL/releases/OpenGL-includes.zip | | Simply unzip it into the installation directory of GHC 5.04.1 or 5.04.2 | (e.g. C:\ghc\ghc-5.04.2 for the default 5.04.2 installation). It would | be nice if upcoming WinDoze installers for GHC were shipped with those | headers. | | Cheers, | S. | | _______________________________________________ | Cvs-ghc mailing list | Cvs-ghc@haskell.org | http://www.haskell.org/mailman/listinfo/cvs-ghc
