Hi: Here is what Cabal does: $ ./Setup.lhs -v build C:\DOCUME~1\vivian\LOCALS~1\Temp\ghc139100_0\ghc139100_0.hc:8:37: ../src/Matlab/C/CMatrix.h: No such file or directory Reading parameters from D:\Apps\MSYS\1.0\local\src\MatlabCompiling\matlab.buildinfo Preprocessing library Matlab-0.0.1... D:\Apps\MSYS\1.0\local\bin\c2hs.exe -C -D__GLASGOW_HASKELL__=606 -C -Ic:\Apps\MATLAB704\bin\win32\..\..\extern\include -o src\Matlab\C\CMatrix.hs src\Matlab\C\CMatrix.chs D:\Apps\MSYS\1.0\local\bin\c2hs.exe -C -D__GLASGOW_HASKELL__=606 -C -Ic:\Apps\MATLAB704\bin\win32\..\..\extern\include -o src\Matlab\C\CMat.hs src\Matlab\C\CMat.chs c2hs.exe: Matlab/C/CMatrix.chi not found in: . Setup.lhs: got error code while preprocessing: Matlab.C.CMat Here is my command that works (from MatlabCompiling/test) $ c2hs --cppopts=-I/c/Apps/MATLAB704/extern/include --include=../src ../src/Matlab/C/CMatrix.chs Here is the addition to matlab.buildinfo which makes Cabal work: c2hs-options: --cppopts=-I/c/Apps/MATLAB704/bin/win32/../../extern/include --include=src I'm also attaching a file which should recreate all the errors that I've found on MinGW/WinXP. Note that there are files outside the cabal hierarchy to simulate headers/library which are already on the system and outside the packager's control. Cheers, Vivian

Hi Duncan,
I added cppOptions because in the Cabal.cabal file there was a comment to add cppOptions and so I did it.
Ok.
With respect to c2hsOptions, the problem is that c2hs passes options to the CPP nonstandardly (with --cppopts=), so even if I have an -I* option in my ccOptions that gets passed to c2hs, this works for c2hs, but doesn't get passed to the cpp that c2hs uses.
Sorry, I still don't see it fully. Could you say exactly what the c2hs command line is that you use when it works and what command line cabal uses that does not work (and that your patch solves).
I've sent a message to the c2hs/cabal mailing list with a dummy package that recreates all the problems I had on mingw/WinXP.
I'm not sure that we got this. Could you send it again, perhaps ccing it to me directly.
