Sorry it took me so long to get back to you. I don't follow this mailing list as closely as I follow libraries@haskell.org. Cabal bugs should be reported there or CC'd to me... Peter Simons <simons@cryp.to> writes:
Hi,
I've run into a problem when trying to build a package with Cabal using a different GHC version than the one found in the $PATH. It looks like this:
$ runghc Setup.lhs configure --with-compiler=/opt/ghc/bin/ghc-6.2.2 Warning: No license-file field. Configuring hsemail-0.0-2005-02-14... configure: looking for package tool: ghc-pkg near compiler in /opt/ghc/bin/ghc-6.2.2 Cannot find package tool: /opt/ghc/bin/ghc-pkg.2
Apparently there's some problem in the path manipulation code.
Definitely sounds like a bug. I'll attack this ASAP.
I also wonder why Cabal complains about a missing License field, because the file contains:
License: GPL
Is it complaining about the "license-file" field? It would like you to also provide a license file in order to be more legal. The "license" field is more for quick listing and automated tool uses, but who knows if its legally binding. Cabal warns you when you don't have a license-file field.
Last but not least, Cabal fails when the package description file contains comments after the value. The entry
Extensions: CPP -- some comment
Yes, comments have to start at the beginning of the line, as the user manual says. Thanks for the bug report. peace, isaac
