Although it might be a pain in the arse to some degree, is there any reason why 'base' is considered special? As an example, I've come across a fair number of libraries/apps that (presumably) compile against a previous version of OpenGL, but not the current latest. Given it's impossible to test any package against libraries that don't yet exist, shouldn't the upper bound be required for all package dependencies? Just curious. :) ta, Sam -----Original Message----- From: haskell-cafe-bounces@haskell.org [mailto:haskell-cafe-bounces@haskell.org] On Behalf Of Neil Brown Sent: 12 November 2009 14:36 To: Jeremy O'Donoghue Cc: haskell-cafe@haskell.org Subject: Re: [Haskell-cafe] Cabal upload issue Jeremy O'Donoghue wrote:
Hi all,
I'm in the process of trying update the revisions of wx (part of wxHaskell) on hackage.
I'm getting an error I find slightly surprising: ... Library if flag(splitBase) build-depends: base >= 3, wxcore >= 0.12.1.1, stm
Change this last line to base >= 3 && < 5 to get rid of the warning. I think the idea is that if base becomes version 5, it will likely break your code, so you should specify ahead of time that this library isn't currently designed to work with a version of base beyond 4. That way when someone installs your package in the future and you haven't tested with base 5, cabal will know to use base 4 for your library.
