Hi,

I've built and installed c2hs on my Mac OS X system now. I read through the research paper on c2hs available on the website for c2hs and decided I would need to try it out to learn it. But it gives me errors which I am having trouble trying to understand. Here are the error messages:

c2hs file.chs

powerpc-apple-darwin8-gcc-4.0.1: c: No such file or directory powerpc-apple-darwin8-gcc-4.0.1: c: No such file or directory powerpc-apple-darwin8-gcc-4.0.1: warning: '-x -x' after last input file has no effect powerpc-apple-darwin8-gcc-4.0.1: no input files c2hs: Error during preprocessing custom header file

c2hs runs cpp -x c ${header} for the header file you specify. You can either specify a header file on the commend line or use #include's in the .chs file. c2hs should generate a .h file itself in that case but it looks like it isn't for some reason. You can find out what it is really doing by running: c2hs --dump trace file.chs btw, the better mailing list for this stuff is the c2hs mailing list: c2hs@haskell.org Duncan
