Hi David,

     I commented out "Hs-source-dirs"

Executable         QNameTest
--   Hs-source-dirs: Swish/
   Main-Is:        HaskellUtils/QNameTest.hs
   Other-Modules:  HaskellUtils.QName

Here is what I got:

vigalchin@ubuntu:~/FTP/Haskell/Swish-0.2.1$ cabal build -v
Warning: swish.cabal: A package using section syntax should require
"Cabal-Version: >= 1.2" or equivalent.
Creating dist/build (and its parents)
Creating dist/build/autogen (and its parents)
Preprocessing library swish-0.2.1...
Preprocessing executables for swish-0.2.1...
cabal: can't find source for HaskellUtils.QName in ., dist/build/autogen
vigalchin@ubuntu:~/FTP/Haskell/Swish-0.2.1$

I seem to remember that on the Haskell Wiki there is an example of building/linking an "Executable" but I cannot find. ??

Regards,

Vasili

I'm guessing QNameTest.hs imports Swish.HaskellUtils.QName, which
means that GHC is looking for a file Swish/HaskellUtils/QName.hs. But
you've indicated that the root of the source tree is a directory
called Swish/, so GHC is looking for
Swish/Swish/HaskellUtils/QName.hs.

I'd try eliminating the hs-source-dirs field.
