blah.cabal isn't a Haskell file, you need a file Setup.hs that you can 'runhaskell'. Setup.hs need only contain the following three lines: #!/usr/bin/env runhaskell import Distribution.Simple main = defaultMain -k -- If I haven't seen further, it is by standing in the footprints of giants

Hi!

I'm trying to set up a project with both src and lib directories with cabal. My blah.cabal file looks like:

Library Build-Depends: base Exposed-Modules: Foo hs-source-dirs: lib/foo

Executable hai Build-depends: base Main-is: Bar.hs ghc-options: -O hs-source-dirs: src/bar Other-Modules: Foo extra-libraries: Foo extra-lib-dirs: lib/bar

You will have to use: 

Library Build-Depends: base Exposed-Modules: Foo hs-source-dirs: lib/foo

Executable hai Build-depends: base Main-is: Bar.hs hs-source-dirs: src/bar, lib/bar Other-Modules: Foo

Theo only downside is that the module Foo will be built twice.

What's wrong?

Currently there is no way for the hai executable to use "build-depends: blah", (though that's the obvious way in future that we could let an exe depend on a lib in the same package). See: http://hackage.haskell.org/trac/hackage/ticket/89 http://hackage.haskell.org/trac/hackage/ticket/276 Duncan
