[Haskell-beginners] "cabal install wxcore --enable-shared" Error

[Paulo Pocinho]

I'm trying to build an application using "ghc -dynamic mywxapp.hs".

Everything not involving wx compiles with dll linking.
However, I can't build the required dynamic libraries for wxcore.

Using "cabal install wxcore --enable-shared" gives the following:

collect2: ld returned 1 exit status
Creating library file: dist\build\libHSwxcore-0.12.1.6-ghc7.0.2.dll.a
cabal: Error: some packages failed to install:
wxcore-0.12.1.6 failed during the building phase. The exception was:
ExitFailure 1

Using "cabal install wxcore --enable-shared  --enable-split-objs"
gives the following:

cabal: Error: some packages failed to install:

Is it possible to fix?
