I was trying to compile HOpenGL using GHC-5.02 in my windows98 platform. I still needed to use cygwin because otherwise I wouldn't have how to issue commands like "configure", "make depend", "make', ... After some rearrangements, the last step ("make") gives me some warnings and errors concerning file GL_BinaryIO.hs, such as: GL_BinaryIO.hs:21: Warning: Variable `hPutBufFull' is deprecated: renamed to hPutBuf GL_BinaryIO.hs:21: Warning: Variable `hGetBufFull' is deprecated: renamed to hGetBuf GL_BinaryIO.hs:193: Couldn't match `Addr' against `Ptr a' Expected type: Addr -> Int -> IO () Inferred type: Ptr a -> Int -> IO () In the application `hPutBufFull handle' In the first argument of `sizedInParam', namely `(hPutBufFull handle)' GL_BinaryIO.hs:198: Couldn't match `IO (Ptr a)' against `t -> t1' Expected type: IO (Ptr a) Inferred type: t -> t1 Probable cause: `malloc' is applied to too many arguments in the call (malloc (sizeOf x)) In a 'do' expression pattern binding: buf <- malloc (sizeOf x) I think implementation of module IOExts may have changed, and the file GL_BinaryIO.hs deals with its older version. I would like to ask three questions then: 1. Is it worth trying to solve this problem, or will I find a lot of other similar problems? 2. If it is, how can I solve it? 3. If it is not, is there another way to compile HOpenGL using GHC-5.02 under a Windows98 platform? I know Sven is working on this, but is there a reasonable solution by now? Thanks, -- Andre
