Re: [Haskell-beginners] can't install hackage package

i have now installed pcre-light separately, it still doesn't work. i think the problem is that it claims that ghc is an unknown package. that was working on other computers. maybe there's something note quite right about the way it's all configured on the (just released) fedora18 haskell platform setup?

it's ghc 7.4.1 that came with fedora.

yes i wiped ~/.ghc and ~/.cabal and it's still the same problem.

i didn't know those cabal flags. i see some infos in the log, maybe i can even figure it by myself now:

Hi.

...

I've been using this hackage package "rex" without problems on two computers (linux, windows) but now I fail setting it up on a third computer which confuses me, and the error message is not really enlightening for me:

$ cabal update Downloading the latest package list from hackage.haskell.org $ cabal --version cabal-install version 1.16.0.2 using version 1.16.0.3 of the Cabal library $ cabal install rex Resolving dependencies... cabal: Could not resolve dependencies: trying: rex-0.3.1

That's a bad error message indeed ;)

What's your GHC version? Is this an otherwise clean package database? Can you post the output of "cabal install rex --dry-run -v3"? If the log is too long to attach to a mailing list mail, just mail it to me personally.

Cheers, Andres
