[Haskell-cafe] OpenGL Linking Issue

[Mark Spezzano]

Hi,

 

I hope I’m posting to the right forum. 

 

I’ve got OpenGL up and running on my Windows Vista machine (finally!) and it
runs perfectly well under Eclipse, bringing up a window with a rendered
image as expected.

 

The only issue starts when I try to compile the program without Eclipse
(using GHC rather than GHCi like Eclipse does).

 

I type:

 

C:\Users\Mark\workspace2\OpenGLPractice\src>ghc --make Test1.hs

 

And get the following output

 

Linking Test1.exe ...

C:\Program
Files\Haskell\GLUT-2.1.1.2\ghc-6.10.1/libHSGLUT-2.1.1.2.a(Extensions.

o):fake:(.text+0xcc): undefined reference to `glutGetProcAddress at 4'

collect2: ld returned 1 exit status

 

What’s happening here? Obviously it’s a linking issue, but I was wondering
whether I need to include some library or file or option to ghc so that it
links correctly.

 

Cheers,

 

Mark Spezzano
