Re: [HOpenGL] Installation (ok!), but ...

Hi, now, I had this problem :((((( [root@PANDORA ~]# ghc --make Planet.hs Chasing modules from: Planet.hs Skipping Main ( Planet.hs, Planet.o ) Linking ... /usr/bin/ld: cannot find -lglut collect2: ld returned 1 exit status Thanks, Sandra Patrick Scheibe escreveu:Hi, Ok, there are some things you have to know: 1. You have to tell ghc, that you want the HOpenGl Package when you compile some stuff that needs HOpenGL. You can do this with ghc -package OpenGL 2. It is maybe a good idea to use the --make option. That checks the dependencies. I think that will not solve your problem. For some reason the ghc doesn't find the right files. It looks like that you use the (old) samples from the separate HOpenGL package. You have to use the samples from the ghc source under: ghc-6.4/libraries/GLUT/examples/RedBook/Planet.hs That is very important because the HOpenGL package from the website is very different from the ghc HOpenGL package. These two things have different APIs... So try this: Go to the ghc website and download the ghc6.4 source. Go to the path: libraries/GLUT/examples/RedBook/ and then try to compile the sample with ghc --make -package OpenGL Planet.hs This should work.

Hi,

I installed GHC 6.4, but I don´t know how to running a program, like Planet.hs. I had this problem:

[root@medusaLinux redbook_HS]# ghc Planet.hs -v Glasgow Haskell Compiler, Version 6.4, for Haskell 98, compiled by GHC version 5.04.3 Using package config file: /usr/local/lib/ghc-6.4/package.conf Hsc static flags: -static *** Checking old interface for Main: *** Parser: *** Renamer/typechecker: Planet.hs:15:0: Failed to load interface for `GL': Could not find module ` GL': locations searched: GL.hi GL.hi-boot *** Deleting temp files Deleting: /tmp/ghc3765.s Warning: deleting non-existent /tmp/ghc3765.s

Thanks, Sandra

Hi,

At installation of HOpenGL, I had this problem:

[snip]

HOpenGL is not a stand-alone package any more. Just install GHC 6.4 and it'll be there.
