Dear Haskell Cafe, I tried installing the haskell openal library via cabal install openal I get the following error: ... [ 7 of 30] Compiling Sound.OpenAL.ALC.QueryUtils ( Sound/OpenAL/ALC/QueryUtils.hs, dist/build/Sound/OpenAL/ALC/QueryUtils.o ) Sound/OpenAL/ALC/QueryUtils.hs:66:1: Unacceptable argument type in foreign declaration: ALCdevice When checking declaration: foreign import ccall unsafe "static alcGetString" alcGetString :: ALCdevice -> ALCenum -> IO (Ptr ALCchar) Sound/OpenAL/ALC/QueryUtils.hs:102:1: Unacceptable argument type in foreign declaration: ALCdevice When checking declaration: foreign import ccall unsafe "static alcGetIntegerv" alcGetIntegerv :: ALCdevice -> ALCenum -> ALCsizei -> Ptr ALCint -> IO () Sound/OpenAL/ALC/QueryUtils.hs:120:1: Unacceptable argument type in foreign declaration: ALCdevice When checking declaration: foreign import ccall unsafe "static alcIsExtensionPresent" alcIsExtensionPresent_ :: ALCdevice -> Ptr ALCchar -> IO ALCboolean Failed to install OpenAL-1.4.0.1 cabal: Error: some packages failed to install: OpenAL-1.4.0.1 failed during the building phase. The exception was: ExitFailure 1 The version of my openal installation is 1.14-1. I also tried to install via darcs, but the error is the same. Any ideas? Greets Gary
