Hello, The following is a fragment in my cabal file: Executable GraphPartitionTest Main-Is: Swish.HaskellRDF.GraphPartitionTest.hs Other-modules: Swish.HaskellRDF.GraphPartition Swish.HaskellRDF.GraphClass Swish.HaskellUtils.ListHelpers Swish.HaskellUtils.TestHelpers When I try to do a build I get: Setup: can't find source for Swish in . Cabal/Setup seem to be looking in the current directory for source but as you can see I gave "full" paths, i.e. Swish.HaskellRDF* or Swish.HaskellUtils*. What I doing wrong? Regards, Vasili

You need to give more detail. For example, is your directory layout like './src/Swish/HaskellRDF.../foo.hs'? In that case, Cabal is looking for './Swish/HaskellRDF.../foo.hs'. You need to tell it to look in src/ and not ./ with a line like 'hs-source-dirs: src/' etc. - -- gwern -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iEYEAREKAAYFAkopdUsACgkQvpDo5Pfl1oLbCgCfWI1MZOyWnsyAkra88S/LC506 7oMAoJhv5hDcc1Ypqq0hLncB2t/1Yuby =ADOt -----END PGP SIGNATURE-----

for directory structure I Swish-0.2.1/Swish/HaskellRDF and Swish-0.2.1/Swish/HaskellUtils ... there are deeper directories but that distract from the discussion ... to make things concete: 1) swish.cabal is directly under Swish-0.2.1 2) GraphPartitionTest.hs is under Swish-0.2.1/Swish/HaskellRDF 3) GraphPartitionTest's dependencies are either under HaskellRDF or HaskellUtils Hope this helps to make things clearer. I added a "Hs-source-dirs" but that help. I did a "ruinhaskell Setup -?" to check on options. I don't see any verbose mode so that when I do "runhaskell Setup build" I can moniitor the progress of my build for diagnostic purposes! Is there a verbose mode?

Right. You understand why it has to be a filepath and not a module name? Because the module name of an executable would be 'Main', not HaskellRDF.GraphPartitionTest. You can try compiling something like module Foo (main) where main = print "hello world" and see for yourself how it fails.

...

Other-modules: HaskellRDF.GraphPartition HaskellRDF.GraphClass HaskellUtils.ListHelpers HaskellUtils.TestHelpers module 'Swish.HaskellUtils.TestHelpers'"???

Vasili

Right. hs-source-dirs defined all the module paths as relative to Swish/; I think the solution here would be to have something like 'hs-source-dirs: ., Swish/' (or whatever the directory was that the HaskellUtils stuff can be found in if not ./). - -- gwern -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iEYEAREKAAYFAkophlwACgkQvpDo5Pfl1oJkBgCeLBI6CsOOdt4EzJa1CaYzoMd4 aDAAn3HICqcDAR74J7z4v8xkakVJ6bDl =hgRy -----END PGP SIGNATURE-----

If your module statements say Swish in them, e.g. module Swish.HaskellUtils.TestHelpers where .... then you should probably have no hs-source-dirs (or hs-source-dirs: .) and then use Swish.HaskellUtils.TestHelpers. But leave Main-Is: as you have it. -Ross On Jun 5, 2009, at 4:49 PM, Vasili I. Galchin wrote:

The "Main-Is:" line is wrong: it should be:

...

Main-Is: Swish/HaskellRDF/GraphPartitionTest.hs

That is, it should name a filepath (usings slashes), not a module (using dots). Regards, Malcolm
