Re: [Haskell-cafe] Ambiguous module name `System.Directory'
Note that once you upgrade it (to >=0.4), you'll still need to remove the older version to fix the error. I wish cabal-install defaulted to hiding every package it installs. The current behavior of exposing every installed module is unreasonable and confusing. Packages should be namespaces, not just installation aliases. ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
Re: [Haskell-cafe] Ambiguous module name `System.Directory'
Thanks, that's a good idea. One other solution on this one: upgrade system-fileio. The newest version does not contain any conflicting names. As a side point, system-fileio (and system-filepath, which it depends upon) are both excellent packages, I use them all the time at work. Michael On Sat, Aug 27, 2011 at 12:44 AM, Albert Y. C.

[Haskell-cafe] Ambiguous module name `System.Directory'
Hi, i am using ghc version 7.0.3 and a pretty recent version of the haskell-platform. Whenever i use the System.Directory module, i run into this conflict: Ambiguous module name `System.Directory': it was found in multiple packages: system-fileio-0.2.1 directory-1.1.0.0 How can i resolve this conflict permamently (i know about :set -hide-package ... )? And shouldn't there be a rule in the haskell platform which forbids modules of the same name?
