Also, less importantly, how do I generate packages? I have a bunch of .o files (modules) all compiled using -package-name and -c, but I can't find the correct ghc flag to link them into a library (.a/Linux).

You use the usual 'ar' tool for making a .a library, something like: $ ar cru libfoo.a a.o b.o c.o To make this into a package, see the section on packages in the user's guide: http://www.haskell.org/ghc/docs/5.00/set/packages.html Cheers, Simon
