problem with SDL-gfx
Hello! I hope you can help me. I'm trying to use SDL-gfx but it seems it isn't linking it correctly. When I try to run this simple file with runhaskell: import Graphics.UI.SDL.Primitives main = putStrLn "Hello" It gives: sdl.test.hs: <command line>: can't load .so/.DLL for: /home/username/.cabal/lib/i386-linux-ghc-7.10.2/SDL-gfx-0.6.0.1-6rhSP5mw8M00K9S8yASTVF/ libHSSDL-gfx-0.6.0.1-6rhSP5mw8M00K9S8yASTVF-ghc7.10.2.so (/home/username/.cabal/lib/i386-linux-ghc-7.10.2/SDL-gfx-0.6.0.1-6rhSP5mw8M00K9S8yASTVF/ libHSSDL-gfx-0.6.0.1-6rhSP5mw8M00K9S8yASTVF-ghc7.10.2.so: undefined symbol: SDL_initFramerate) Notes: * SDL works fine in all cases. * My system is i386, using Arch Linux. I tried with another computer with x86_64 with Arch Linux and it worked. * It works if I compile it with ghc and run the executable. * I installed the package using cabal install SDL-gfx with no errors. * I installed the library in the OS just in case, and double checked that it exist in /usr/lib/libSDL_gfx.so and that it contains the symbol SDL_initFramerate. * The long *.so library reported by runhaskell also constains SDL_initFramerate. * GHCi gives the same error (when executing main). * I'm trying to make a cabal package that uses this library, and cabal gave the same error within the sandbox.

Hello Martín, SDL-gfx maintainer here. Could you try: runhaskell -L/usr/include/SDL/ -lSDL_gfx prova.hs (this works in Debian, modify the -L dir appropriately if you are using Arch).
Same error :/
The include folder (/usr/include/SDL/) contained the expected files.
(SDL_framerate.h and others)
I even recompiled and reinstalled the library but still says the same.

Gotcha, I forgot to to put an extra-libraries: in the .cabal file (let me thank Ivan Perez, who had a similar problem on sdl-image and provided the right diagnosis). I have uploaded the new version to hackage, install it and then type: runhaskell -lSDL_gfx your-test-file.hs It should work. Ciao -F
It works perfect now :D :D
Now I can use it in my project, I didn't even need the -lSDL_gfx.
Many thanks for this fast fix!
