I am using Windows Vista.
I installed the following:

- ghc 6.8.3 (using official Windows binary installer)
- MinGW (from http://nuwen.net/mingw.html)
- SDL binding (from

I am trying to compile the following program:

    module Main where

    import qualified Graphics.UI.SDL as SDL

    main = do
        SDL.init [SDL.InitEverything]

I get the following error:

C:\Users\client\code\sandbox>ghc --make Example.hs

(http://www.libsdl.org/faq.php?action=listentries&category=4#48)  I
should use "int main(int argc, char *argv[])", not "int main()" nor

Can anyone compile the above snippet on windows machine?
I am using SDL library that is shipped with MinGW distribution that I'm using.
I also recompiled SDL haskell binding with official SDL windows binary
(http://www.libsdl.org/release/SDL-devel-1.2.13-mingw32.tar.gz). But I
get the same undefined reference to SDL_main linker error.

Do I need to have specific main IO action so that SDL would work in Haskell?

Thank you.
