ghc --make -package OpenGL -package GLUT something.hs
I get nothing but undefined references in the linking phase.
C:\Program
Files\Haskell\GLUT-2.1.1.2\ghc-6.11.20081202/libHSGLUT-2.1.1.2.a(Window.o):fake:
(.text+0x15): undefined reference to `glutWarpPointer'
Does ghc-pkg describe OpenGL tell you that the package needs some gl C
lib? Eg "ld-options: -lGLU -lGL -lm"
Yes:
$ ghc-pkg field OpenGL
import-dirs,library-dirs,hs-libraries,include-dirs,includes,cc-options,ld-options
import-dirs: "C:\\Program Files\\Haskell\\OpenGL-2.2.1.1\\ghc-6.11.20081202"
library-dirs: "C:\\Program Files\\Haskell\\OpenGL-2.2.1.1\\ghc-6.11.20081202"
hs-libraries: HSOpenGL-2.2.1.1
include-dirs: "C:\\Program
Files\\Haskell\\OpenGL-2.2.1.1\\ghc-6.11.20081202\\include"
includes: HsOpenGL.h
cc-options:
ld-options: -lglu32 -lopengl32
$ ghc-pkg field GLUT
import-dirs,library-dirs,hs-libraries,include-dirs,includes,cc-options,ld-options

When you ghc --make -v, is it actually linking to a gl C lib?
It looks that way:

Btw, is the format for the cabal config file documented somewhere?
I though I had set documentation to True.
At the moment only in the config file itself. It lists all the fields
(commented out) and where there are default values it lists those too.
ah, I wasn't sure whether those '--' were meant to indicate options or
commenting (a comment in the first line might make usage unambiguous?-)
