Hello,
I'm trying to write a 3D renderer in Haskell using SDL bindings (Lemmih)
and OpenGL bindings. When I try to compile my work, ghc runs collect2:
I just rerun collect2 by hand without pre /usr/lib parameter, and it
works. What have I to do or where have to look in to find and resolve
the problem? I use Gentoo 2005.0 and SDL binding from SDLStable brach
installed by hand (I didn't use Portage).
How did you invoke GHC?
Yes, I did (I sad it).
I mean, what command line gave that error message?
I'm sorry, I'm an idiot:

    $ ghc --make Main.hs

I compiling your Haskell + SDL + OpenGL example from haskell wiki and my
modifications (big modifications).

What does 'ghc-pkg describe SDL' say?
See atachment.
Thanks, you're fast!

Hmm, looks like GHC is having issues with -rpath. I'm not sure how to
solve this correctly but one solution would be to remove it from your
package.conf file.
Problem solved. Thank you! Now you have to find a way to correct the
problem in your distribution. Maybe, I can help you with
long-time-low-priority work around SDL... do you have some work for my?
I'm "haskell freshmen" and I need some real-work.

Thank you, one more time.
