What is the problem exactly? Are you using the latest tarball or the darcs version? Duncan

Building Projects under mingw that use c2hs [apologies for repost; archive seemed to scrub text portion, see archive for attached file]

Hi, I have been trying to build a Cabal package that uses c2hs under mingw and have run into some problems. 1) c2hs needed its own options because it has to pass a flag to its invocation of the CPP. I have already submitted this patch. (I also noticed a request for cppOptions in the Cabal.cabal file, so I added that) 2) When c2hs generates the foreign import ccall unsafe "path/to/include.h function" :: Type it doesn't insert the appropriate number of path separators for windows ( i.e. \\ not \) I have this patch sitting in my copy of c2hs. But what I did is really ugly: at around line 567 (process :: FilePath -> FilePath -> CST s ()) I inserted: > outFName' <- getSwitch outputSB > -- on windows the path separator needs to be "\\" not "\" > let outFName = replaceFileSeparator outFName' where replaceFileSeparator is defined as: > replaceFileSeparator :: String -> String > replaceFileSeparator [] = [] > replaceFileSeparator (x:xs) > | x == '\\' = "\\\\" ++ (replaceFileSeparator xs) > | otherwise = x : (replaceFileSeparator xs) this fixes the problem but stinks. 3) when compiling my c2hs generated .hs file, the c2hs generated .h file is not being found. $ ./Setup.lhs -v build Reading parameters from D:\Apps\MSYS\1.0\local\src\mingw-c2hs-cabal-test\cabal-root\mingw- c2hs-cabal-test.buildinfo Preprocessing library Mingw-c2hs-cabal-test-0.0.1...
