Hello,
I am trying to use the SDL-mixer bindings to play wav files. I've hit a wierd error and I can't figure out how to solve it:
Prelude> import Graphics.UI.SDL.Mixer.Music Prelude Graphics.UI.SDL.Mixer.Music> loadMUS "test.wav" Loading package SDL-0.5.4 ... linking ... done. Loading package SDL-mixer-0.5.2 ... linking ... <interactive>: /home/norbert/bin/lib/SDL-mixer-0.5.2/ghc-6.8.2/HSSDL-mixer-0.5.2.o: unknown symbol `Mix_LoadWAV' ghc-6.8.2: unable to load package `SDL-mixer-0.5.2'
I've looked up the source code; Mix_LoadWAV seems to be #defined, so I suspect it's some kind of library path issue but I don't grok the whole system well enough to figure it out; maybe someone could point me in the right direction?
Have the issue now on Ubuntu 8.04 and previously had the same issue when I tested it on a FreeBSD box. I did install all of the "libsdl-*-dev" in the Ubuntu repo.
Ah, well spotted. I get the same issue on Arch, in ghci: Prelude> import Graphics.UI.SDL.Mixer.Music Prelude Graphics.UI.SDL.Mixer.Music> loadMUS "/usr/share/hback-0.0.3/sounds/t.wav" <interactive>: /usr/lib/SDL-mixer-0.5.2/ghc-6.8.2/HSSDL-mixer-0.5.2.o: unknown symbol `Mix_LoadWAV' ghc-6.8.2: unable to load package `SDL-mixer-0.5.2' Looking in the source we see: foreign import ccall unsafe "Mix_LoadWAV" mixLoadWAV :: CString -> IO (Ptr ChunkStruct) Lemmih, any ideas? -lSDL and -lSDL_mixer seem to be there. -- Don
