[Haskell-cafe] GLUT (glutGet undefined reference)

[Paul Keir]

Thanks Kazuya, that link is perfect.

Basically, I have to explicitly add -lglut :

ghc -package GLUT -lglut HelloWorld.hs -o HelloWorld

Great. GLUT (and now FreeGLUT) remains the simplest
and most reliable "standard" cross-platform OpenGL
windowing API.

(It seems from the link that the information used by
ghc-pkg is wrong, and stems from the GLUT package's
relationship to libraries known as Xmu and Xi.)

Cheers,
Paul
