I've never had a problem with cabal on windows. I use it instead of
makefiles and I'm reasonably happy with it.

Perhaps your .cabal file is not correct or your cabal version is too
old? It's very hard to say without detailed error messages and a
clear description of what you're doing (with sample code).

I only create a DLL from haskell and link that in a C++ application.
I haven't tried the other way. Probably over the next month or so the
DLL I'm creating in Haskell will need to access an existing DLL.
Hopefully this will work fine.

I have no idea. I'm fairly new to using Haskell in windows.
