Dear Lemmih,
SDL-ttf-0.6.1 fails to build with GHC 7.6, which is out for
quite a while now:
Preprocessing library SDL-ttf-0.6.1...
[1 of 7] Compiling Graphics.UI.SDL.TTF.Version
( dist-ghc/build/Graphics/UI/SDL/TTF/Version.hs,
dist-ghc/build/Graphics/UI/SDL/TTF/Version.o )
[2 of 7] Compiling Graphics.UI.SDL.TTF.General
( Graphics/UI/SDL/TTF/General.hs,
dist-ghc/build/Graphics/UI/SDL/TTF/General.o )
Graphics/UI/SDL/TTF/General.hs:26:1:
    Unacceptable result type in foreign declaration: IO CInt
    When checking declaration:
      foreign import ccall unsafe "static TTF_Init" ttfInit :: IO CInt
Graphics/UI/SDL/TTF/General.hs:32:1:
    Unacceptable result type in foreign declaration: IO CInt
    When checking declaration:
      foreign import ccall unsafe "static TTF_WasInit" ttfWasInit
        :: IO CInt
Would it be possible for you to upload a compatible version to hackage?
Thanks,
Joachim
