Sorry Ashley, I hope you didn't feel I was picking on you in particular. I realise it might have looked that way. On Fri, 2008-10-10 at 11:08 -0700, Ashley Yakeley wrote:

Failing due to -Werror.
NOOOOooooooooooooooooooo!!!!!!
This is the reason that hackage now rejects the use of -Werror in released packages. It causes unnecessary breakage when new compilers add new warnings.
Warnings in a build process should be fixed, not ignored (and, I would say, fixed by whoever introduced the warning or otherwise broke the build).
Yes indeed. So it's appropriate for development builds.
Hackage, on the other hand, is right to reject -Werror in .cabal files, as there the build is really part of the install process and should be as lenient as possible. I pass --ghc-options="-Wall -Werror" to cabal in a Makefile in most of my projects, so that my development build process is strict.
Right. Putting -Wall in the ghc-options in the .cabal file is fine too of course. Lots of packages do that. Duncan
