Compile SDL with cabal in MinGW

Question

I’m trying to install SDL within cabal for Haskell, in MinGW, but I got some problems. cabal can’t find the C library, and I don’t know why. Here some info:

• I have downloaded both the dev and runtime library of the SDL1.2 ;
• For the dev version, I make native it: it’s installed in /usr/include/SDL and /usr/lib ;
• I tried a cabal install SDL, it failed because it can’t find both the header file and the lib ;
• Then, I give it another try with cabal install SDL --extra-include-dirs=/usr/include/SDL --extra-lib-dirs=/usr/lib. It finds the header file but still not the lib ;
• I copied the runtime library SDL.dll in /usr/lib, still have the same trouble ;
• Finally, I added /usr/lib to both the PATH and LD_LIBRARY_PATH, still can’t find that @!#* C lib.

Do you have an idea?
