Brandon, thank you for your explanation.
I got it working with: ghc --make testGlasPng.hs -LD:\glas\dlls -lglasPng. It
needs both the -L and the -l argument. The dll is in the PATH. I don't
understand why it needs the -L argument. I'll figure this out later. If I use

Unfortunatly the proposed solutions didn't work after all (It worked once, I
think, but.)
Here again the problem:
glasPng.dll is a Delphi dll with the function getPngVersion in it. Calling
convention is stdCall. I want to use this dll. The code:
{-# LANGUAGE ForeignFunctionInterface #-}
mod
Thank you Krzystof! This did the trick. Now I also have a better understanding
what is going on. Great.

My first guess would be missing -l parameter. The examples you have linked
read:
ghc --make compname.hs -lkernel32

Did you annotate the exported function with stdcall? The call
I made a Delphi dll (32 bits windows). This dll exports a function named
getPngVersion. This is a function with no arguments that returns a pointer
to a array of chars.
If I examine the dll with a tools like tdump, I can see the function
getPngVersion on index 1.
Now I want to use this dll in Has
