Hi all, Sorry if this isn't the right list for cabal questions, but I figure that if I couldn't figure this out from reading the docs, you'd at least like to be aware of the doc bug.
I have a library that seems to build ok, and along with it I have a "demo" executable that uses the module. However, that demo executable doesn't build: it seems ghc tries to chase a dependency from the executable back into the library source instead of using the built library. Here's the cabal file: name: DBus version: 0.1 license: BSD3 license-file: LICENSE copyright: Copyright (C) 2006 Evan Martin <[EMAIL PROTECTED]> author: Evan Martin <[EMAIL PROTECTED]> homepage: http://neugierig.org/software/hdbus synopsis: DBus bindings description: Bindings for the DBus API.

However, Demo.hs doesn't itself refer to Internal anywhere: instead (I think?) it ought to use the Internal.o that was built in the library. (As you can see in the log, Internal.o built just fine within the library.) Please let me know if you need any more information. I'll post a quick tutorial on the simplest possible build that uses pkg-config (I saw the earlier thread where it was suggested to support it directly -- that'd help me too) once I get this working. _______________________________________________ cabal-devel mailing list cabal-devel@haskell.org http://www.haskell.org//mailman/listinfo/cabal-devel
