Hi Vivian,
running GHC 6.5.20060831, mingw
1) darcs repo error: Patch 107 can't be applied. Some problem with case-sensitivity. Issue234 of darcs is a bugs report on case-sensitivity, and Heffalump on #darcs is examining this problem.
Heffalump has created a repo that fixes this problem: http://urchin.earth.li/darcs/ganesh/c2hs
Does that also happen if you get the repo with --partial? If yes, maybe we can get around it by adding another, more recent, checkpoint.
2) ./Setup.hs install error:
$ ./Setup.hs install Installing: C:\Apps\MSYS\1.0\local\Haskell\c2hs-0.14.6 \ghc-6.5.20060831 & C:\Apps\MSYS\1.0\local\Haskell\bin c2hs-0.14.6... '.' is not recognized as an internal or external command, operable program or batch file.
Some problem with backslashes and windows.
I got around this problem by installing by hand.
Yes, I am sorry, this is a known problem on windows, which is on the list of things to be fixed.
3) syntax error
$ c2hs --cppopts=-I/c/Apps/MATLAB704/extern/include --include=c:/Apps/MATLAB704/extern/include matrix.h MxMatrix.chs c2hs.exe: Generic fatal error.
C:/Apps/MSYS/1.0/mingw/bin/../lib/gcc/mingw32/3.4.2/../../../../include/float.h:125: (column 8) [FATAL]
Syntax error! The symbol `__attribute__' does not fit here.
__attribute__ is a not very well documented extension of gcc. c2hs can handle many cases of __attribute__, but unfortunately some don't work yet. However, there is a work around. Please see the following message from the list archive: http://www.haskell.org/pipermail/c2hs/2006-May/000577.html Manuel
