To be able to share code between your library and your tests, you should either
* Have a separate directory for the library sources and the test sources. For example, put Ast.hs and Parser.y in 'src' and put 'Hs-source-dirs: src' in the library section. Put RunTests.hs in 'tests', and put 'Hs-source-dirs: tests' in the test-suite section. This is the preferred way. * Alternatively, don't specify 'sample' as a build-depends in the test-suite. Note that this will mean that Ast and Parser will get compiled twice.
Right now, cabal somehow mixes types from the files compiled as part of the test suite with types imported from the library.
I see -- thanks! I'll give that a shot as soon as I get a chance. Richard
