(sorry for the duplication, forgot to reply to the mailing list too) Well, I did, I've completely unregistered the package, Did a check and recache, both completed with no problem. In detail what's happening is, I'm building a tool that requires Haskell-src-exts, So I upgraded to the 1.9.0 release yesterday and all went fine. However when I try to build my tool using my cabal file, it proceeds to download all dependencies and reinstalling them,, (including Haskell-src-exts) even though They are all already installed (gathered that from the output of ghc-pkg list). It does this everytime, so everytime It tries to build all dependencies and then the tool. But if I try to load the file in GHCI, it also says it can't find the packages. -----Original Message----- From: daniel.is.fischer@web.de [mailto:daniel.is.fischer@web.de] Sent: Friday, April 16, 2010 13:36 To: haskell-cafe@haskell.org Cc: Phyx Subject: Re: [Haskell-cafe] ghc package problem Am Freitag 16 April 2010 11:28:54 schrieb Phyx:
Hi all,
I'm having a rather weird problem,
Ghc-pkg list shows a package installed but doing a ghc -make will give an error saying that It can't find a module that's supposed to be in the installed package.
And cabal install always reinstall all the dependencies on every change. It doesn't seem to see that they're already installed.
Can we have more details, please? As a first idea, you might try ghc-pkg unregister offending-package cabal install offending-package
