Hello

I have problems with Cabal failing to build simple packages if C-Sources are inside a subdirectory.

Thanks for the report; this shouldn't be hard to fix.

C-Sources: c_src/foo.c

I didn't anticipate doing this, but it makes sense, since you can't specify the path names of executables with the dot syntax as you can with Haskell sources.

Build creates c_src/foo.o => dist/build/foo.o (from the C-Sources build instruction in Distribution.Simple.Build). In the later stage it tries to look for the object file in dist/build/c_src/foo.o which fails.

My preference would be to fix the build stage so that it puts the .o file in the place where the link stage is looking for it. Otherwise, I guess you could get .o files overwriting each-other if they have the same name!

A complete minimal example is at http://www.cs.helsinki.fi/u/ekarttun/haskell/cfail.tar.gz

Thanks. I think I'll be able to fix this tonight. Are you using the tarball from the web page, or are you checking things out via darcs? peace, isaac
