Hi all, I've been playing around with the package mechanism in ghc which is great. However it took me quite a while to realise that when I compile a module (say Foo.hs, for a package) with profiling, the .hi file must be named Foo.p_hi, and not Foo.hi, when it appears in the "import_dirs" directory. When the interface was called Foo.hi and I tried to use the package the compiler complained: ghc-5.04: can't find module `Foo' (while processing "Main.hs") this is with ghc --make I might have realised the problem earlier if the error message had said something about what file it was looking for, something like: "couldn't find Foo.p_hi in [wherever it was looking]" Although the documentation for packages mentions the "_p" suffix behaviour for library archives I don't think it mentions the suffix for interface files. Perhaps creating packages with profiling should have its own section in the documentation? Cheers, Bernie
