Re: [Haskell-cafe] SDL program under MinGW

Yes, with some modifications. I used SDL-1.2.13, not SDL-1.2.12. Also, my Include-Dirs has include\SDL, not include: C:\Users\client\code\SDL-1.2.13\include\SDL If I don't put include\SDL, I get errors like Graphics\UI\SDL\General.hsc:1:17: SDL.h: No such file or directory And I used the following command to configure: C:\Users\client\Downloads\SDL-0.5.4>runghc Setup.lhs configure --prefix=C:\Users\client\haskell --datadir=$prefix\share --user it builds and installs fine. I only get linker error (undefined reference to SDL_main) when I compile a program that uses SDL binding. On Sun, Dec 7, 2008 at 4:23 AM, Bit Connor wrote:

Did you follow the instructions described in the WIN32 file?

Hi.

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 http://hackage.haskell.org/cgi-bin/hackage-scripts/package/SDL)

I am trying to compile the following program:

module Main where

import qualified Graphics.UI.SDL as SDL

main = do SDL.init [SDL.InitEverything] SDL.quit

I get the following error:

C:\Users\client\code\sandbox>ghc --make Example.hs Linking Example.exe ... C:\MinGW\lib/libSDLmain.a(SDL_win32_main.o)(.text+0x409):SDL_win32_main.c: undefined reference to `SDL_main'

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

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. Sam. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
