Hello I try to set-up a gnu makefile for compiling Haskell programs with GHC. I want to generate dependencies automatically and I want to put my object (.o) files in a binary specifc directories to be able to compile for different architechtures. The problem is when GHC derives the dependencies it names the object file for the Main module to Main.o and not filename.o as it does if I don't specifiy an odir. This gives me two problems, first I cannot have more than one Main module in the same directory as I often need, e.g. for different test programs. The second problem is that it doesn't match my compile command which always names the object files after the the source files by just changing extensions from .hs to .o. So gmake does not recognize dependencies from my Main modules to other modules. I am stuck here. Any ideas?
