[HOpenGL] Win32 GHC cannot link GLUT

[Manuel Garcia Rodriguez]

Hi.

I've installed GHC 6.2, but trying to compile a simple
HelloWindow.hs program fails. The same code runs with
Hugs. Both installs are lastest .msi

import Graphics.UI.GLUT
import Graphics.Rendering.OpenGL

main = do
  getArgsAndInitialize
  createAWindow "Hello Window"
  mainLoop

createAWindow windowName = do
  createWindow windowName
  displayCallback $= clear [ColorBuffer]

H:\Documents and Settings\manuel>ghc -package GLUT -o
HelloWindow HelloWindow.hs
compilation IS NOT required
H:/ghc/ghc-6.2/libHSGLUT.a(Window__53.o)(.text+0x85):ghc14736.hc:

Please report it as a compiler bug to

or http://sourceforge.net/projects/ghc/.

Thanks.
