Re: compiling a dynamic executable

Hi Markus, just saw your question - maybe you already got an answer?

My guess is you're linking with Template Haskell?

Then in this case ghc-7.4 Cabal needs to be patched:

http://pkgs.fedoraproject.org/cgit/ghc.git/tree/Cabal-fix-dynamic-exec-for-TH.patch

I believe this is already fixed in ghc-7.6.

Hope that helps,

Jens
