Hi Philip, Before I got your email, I deregistered unix-2.3.0.0 which made my unix-2.2.0.0 namespace changes visible. However, deregistering seems to made other things worse, e.g. runhaskell Setup.hs configure gives an error message "unknown parameter package: unix-2.3.0.0". Sigh .. how do I get back to where i was in order to do a "hide"? Kind regards, Vasili On Thu, Apr 10, 2008 at 8:22 PM, Philip Weaver wrote:

Hello,

I doing work using Linux. The wrong version (for me) of the unix package seems to be visible. I see possibilities to use ghc-pkg to suppress the unix package that I don't want(2.3.0.0) but that seems dangerious. Details are below . What should I do?

If you don't want to use it, then it's safe to hide it:

ghc-pkg hide unix-2.3.0.0

You can always unhide it later.

You can also tell ghc to use a specific version of a package:

ghc -package unix-2.2.0.0

Of course, you'll need to make sure unix-2.2.0.0 is registered with ghc-pkg.

New subject: library version problem

I am reading currently .. http://www.haskell.org/ghc/docs/latest/html/users_guide/packages.html#instal... 1) Is ghc-pkg intended to be run by most Haskell developers or should ghc-pkg be run by "higher level" tools like Cabal?? 2) my package database appears to be somewhat comprised after I unregistered unix-2.3.0.0. I can no longer build the unix package via "runhaskell". ?? Kind regards, Vasili On Thu, Apr 10, 2008 at 9:39 PM, Galchin, Vasili wrote:
