Hi Mark, When I was on Windows, I had to get the sources of the OpenGL and GLUT packages add an "extra-libraries" line to each of OpenGL.buildinfo.in GLUT.buildinfo.in. Seems to be a bug in the recent library releases. For GLUT, I think I added extra-libraries: glut32 I forget what the library name was for OpenGL. To find out whether these extra-libraries are already listed, try the following shell commands: ghc-pkg describe OpenGL | grep extra ghc-pkg describe GLUT | grep extra I was completely stumped until Sigbjorn Finne suggested there might be missing extra-libraries. - Conal 2009/3/17 Mark Spezzano

Hi,

Can someone PLEASE help me to understand exactly how to configure OpenGL on Window using Haskell. I'm using Eclipse IDE.

When I try to run the file Test1.hs in GHCi then I get the following error:

Loading package syb ... linking ... done.

Loading package base-3.0.3.0 ... linking ... done.

Loading package array-0.2.0.0 ... linking ... done.

Loading package containers-0.2.0.0 ... linking ... done.

Loading package OpenGL-2.2.1.1 ... can't load .so/.DLL for: GL (addDLL: could not load DLL)

Prelude Main>

I've copied the GLUT dll into Windows/System32.

Is there some flag or option that I need to enable to tell Haskell where to go to link in the library. What do I do with the other .h and .lib files from GLUT?

Thanks

Mark
