Thanks, for your report. It was my fault. I should not have modified utils/hsc2hs/Main.hs as described in the following links. http://article.gmane.org/gmane.comp.lang.haskell.glasgow.user/13583 http://hackage.haskell.org/trac/ghc/ticket/1395 A fix is to replace your file <prefix>/lib/ghc-6.8.2/hsc2hs-bin with a new one that you can download from: http://www.informatik.uni-bremen.de/agbkb/forschung/formal_methods/CoFI/hets... (635468 Bytes) a ppc version from: http://www.informatik.uni-bremen.de/agbkb/forschung/formal_methods/CoFI/hets... (800044 Bytes) <prefix> above is /usr/local (or the one you've configured with) Does someone have a cute command to easily update this file in a binary distribution (without unpacking and repacking), so that Ian can replaced my binary-dists (replacing hsc2hs-bin manually is a bit of a pain).

Hi Christian,

I'm using your OS X (Tiger) Intel ghc-6.8.2 distribution downloaded from haskell.org. So far everything worked great until I run into one problem compiling zlib 0.4.0.1. Running build command I get the following error:

Preprocessing library zlib-0.4.0.1... ghc-6.8.2: unrecognised flags: -F/Users/asmyczek/Library/Frameworks Usage: For basic information, try the `--help' option. compiling dist/build/Codec/Compression/Zlib/Stream_hsc_make.c failed command was: /opt/local/bin/ghc -c -package base-3.0.1.0 -package bytestring-0.9.0.1 -F/Users/asmyczek/Library/Frameworks dist/build/Codec/Compression/Zlib/Stream_hsc_make.c -o dist/build/Codec/Compression/Zlib/Stream_hsc_make.o

I'm newbie to Haskell, Cabal etc. and not sure what the root cause of this problem is. Google did not find any concrete solution as well. Do you have an idea what the problem could be or maybe some hints where I can start to dig into?

Thanks, Adam
