[Haskell-cafe] cabal issue
Given that I have the dependant packages already installed when I do $ cabal install --dry-run --global buildwrapper Resolving dependencies... In order, the following would be installed: mtl-2.1.1 (new version) aeson-0.6.0.2 (reinstall) changes: mtl-2.0.1.0 - 2.1.1 parsec-3.1.2 (reinstall) changes: mtl-2.0.1.0 - 2.1.1 regex-base-0.93.2 (reinstall) changes: mtl-2.0.1.0 - 2.1.1 regex-tdfa-1.1.8 (reinstall) changes: mtl-2.0.1.0 - 2.1.1 buildwrapper-0.5.2 (new package) And that build wrapper doesn't have a defined dependency version number for MTL can someone tell me why cabal is trying to install a new version of MTL ?

Re: [Haskell-cafe] cabal issue
Have solved the issue with help from JP Moresmau. Used the command cabal install --dry-run --verbose=3 --global build wrapper And this gave enough detailed info to enable me to remove the conflict and resolve the issue. Thanks goes to JP !

[Haskell-cafe] Cabal issue
I understand that this may have been addressed before on this list in some form, so I'll be brief: Had problem with deprecated package, was told my only option was to wipe my Haskell install and start over. Is this true and if so, doesn't this mean that Cabal (or the package management system that it is a part of) is broken?

Re: [Haskell-cafe] Cabal issue
Not what you asked for, but.. Although the documentation looks somewhat cryptic, and I have not use it at all, a nix + cabal option seems to be in the works. Search google for nix haskell. I am guessing that their Hydra continuous build system which is built on top of nix also could do wonders for hackage.

Wiping your installed packages db is easy, so it is often recommended.

Something *really* needs to be done about its absurd willingness to blindly override bootlibs and thereby break things, though. -- brandon s allbery allber...@gmail.com wandering unix systems administrator (available) (412) 475-9364 vm/sms ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
