Configure bug? Re: SOLVED. Re: [Haskell-cafe] Linker Errors For OpenGL / GLUT 'Hello World' Program.

Hello Brandon, Maybe this is a bug in the configure script of Haskell OpenGL or GLUT packages? Any suggestion from the package maintainers (or someone more familiar with these packages)? Thanks! :) __ Donnie On Sat, Sep 20, 2008 at 10:13 PM, Brandon S.

Hello, ghc -package GLUT -lglut Hello1.hs -o Hello1 --- works! :) I'm not sure why I must specify "-package GLUT" and "-lglut" but that prevents the linker errors. Also, shouldn't configure correctly figure out how to link the GLUT libraries? Can someone explain?

Linker Errors For OpenGL / GLUT 'Hello World' Program
by Donnie Jones 20 Sep '08

20 Sep '08

Hello, I am having linker errors when trying the Haskell OpenGL / GLUT 'Hello World' program. Please see my thread that was first posted on Haskell-cafe mailing list. [Haskell-cafe] Linker Errors For OpenGL / GLUT 'Hello World' Program: http://www.haskell.org/pipermail/haskell-cafe/2008-September/047357.htmlAny help would be greatly appreciated. :) Thank you. __ Donnie

Texture3D redbook example not working
by Mark Zander 15 Sep '08

15 Sep '08

Hi, I ran the Texture3D.hs redbook example from GLUT/examples/RedBook. After removing the initial check for error I got the following error from the program: Texture3D: user error (unknown OpenGL call glTexImage3DEXT, check for GL_EXT_texture3D or OpenGL 1.2) I've run the texture3D.c redbook example successfully and see the two colored rectangles displayed successfully. By the way I noticed that the .c code calls glTexImage3D, no EXT used. I'm running opengl 2.0. Mark
