<div dir="ltr"><p>Hello,<br></p><p>I'm trying to build the latest SDL-image package (0.5.2) from Hackage on Windows and encountering problems. These are the steps I've taken so far:</p><p>1. Downloaded SDL 1.2.13 developmental library for Mingw32 to E:\SDL-1.2.13, and SDL_image 1.2.6 developmental library for VC8 to E:\SDL_image-1.2.6.<br>
2. Installed SDL package from Hackage, modifying the SDL.cabal according to the included WIN32 readme file and then runghc Setup.lhs configure/build/install<br>3. Downloaded the SDL-image package from Hackage, modified the SDL-image.cabal file to add the line "Include-Dirs: E:\SDL_image-1.2.6\include\SDL, E:\SDL-1.2.13\include\SDL" so Cabal can find the header files. After doing "runghc Setup.lhs configure", "runghc Setup.lhs build -v" gives me the following output:<br>

</p><p>The results of a limited google search suggests that the __stginit_ZCMain linker error has to do with GHC expecting a main function, but I'm not really sure how that works in context of a library.</p></div>
