Dear all,
I'm having trouble getting Cabal to find packages installed in my user repository.
When I run ghc-pkg list manually, I can see all the required packages, listed in the section for my user repository. When I run ghci I can import said packages as well. Yet when I run ghc on the Setup.hs file of a package which requires said packages, it tells me that the dependencies are missing.
It works when I use --package-db to explicitely point it to the user package.conf. Am I missing an extra flag or something like that to make it take the packages in the user repository into account? I'm using Cabal version 1.6.0.1.
It should just work with the --user option, so we'll need more details. What ghc version are you using exactly? If it's ghc-6.8.x, is the file for the user package db reported by ghc-pkg list correct? What is the output of ghc-pkg list? Mind you, if it was getting the wrong location then I'd expect reading it to fail, if the file did not exist. For ghc-6.8.x Cabal calls ghc-pkg list and parses the output to find the location of the package db files. Then it loads those files directly. For ghc-6.10.x Cabal calls ghc-pkg dump with --global and/or --user and parses the output. Duncan
