This is a regression of some sort since the library operates fine within GHCi for previous versions of GHC. I don't know whether it is a problem with GHCi, the OpenGL library, or some third party. This is the error encountered when a module that uses OpenGL tries to load:
Prelude Main> main Loading package OpenGLRaw-1.2.0.0 ... linking ... ghc.exe: unable to load package `OpenGLRaw-1.2.0.0' Prelude Main> :q Leaving GHCi. <interactive>: C:\...\OpenGLRaw-1.2.0.0\ghc-7.6.1\HSOpenGLRaw-1.2.0.0.o: unknown symbol `__imp_wglGetProcAddress'
I have very little of an idea of what's going on here. It would be rather painful to debug this myself so any insight is appreciated.
I don't know the solution or the culprit, but normally that symbol is defined in opengl32.lib/dll and the OpenGLRaw cabal file mentions it as an extra library. Jason
