Problem upgrading haskell

Currently I have ghc 6.12.1-4 installed and when I try to do a global upgrade with pacman -Syu I get the following error:

error: failed to prepare transaction (could not satisfy dependencies)
:: haskell-deepseq: requires ghc=6.12.1
:: haskell-haskell-src: requires ghc=6.12.1
:: haskell-html: requires ghc=6.12.1
:: haskell-hunit: requires ghc=6.12.1
:: haskell-parallel: requires ghc=6.12.1
:: haskell-platform: requires cabal-install=0.8.0
:: haskell-quickcheck: requires ghc=6.12.1
:: haskell-quickcheck: requires haskell-mtl=1.1.0.2-3
:: haskell-regex-base: requires ghc=6.12.1
:: haskell-regex-base: requires haskell-mtl=1.1.0.2-3
:: haskell-regex-compat: requires ghc=6.12.1
:: haskell-regex-posix: requires ghc=6.12.1
:: haskell-stm: requires ghc=6.12.1
:: haskell-stm: requires haskell-array=0.3.0.0
:: haskell-xhtml: requires ghc=6.12.1

How can I proceed with the upgrade?

Thanks.

Re: Problem upgrading haskell

Ignore the ghc upgrade for now - all your haskell packages need to be rebuilt for it, and that hasn't happened yet.

I added the following line to pacman.conf but it is not working:

IgnorePkg   = ghc haskell-deepseq haskell-haskell-src haskell-html haskell-hunit haskell-parallel haskell-platform haskell-quickcheck haskell-quickcheck haskell-regex-base haskell-regex-base haskell-regex-compat haskell-regex-posix haskell-stm haskell-stm haskell-xhtml

I get the error:

error: failed to prepare transaction (could not satisfy dependencies)
:: haskell-platform: requires cabal-install=0.8.0

Re: Problem upgrading haskell

Just add haskell-platform to the IgnorePkg list and you should be fine.

Re: Problem upgrading haskell

If you notice the ignorepkg line I showed includes haskell-platform, and it doesn't work...

Re: Problem upgrading haskell

Ignore cabal-install as well as ghc. My original advice was to ignore ghc only, btw - not all the dependent packages as well.

I'd recommend that you try to gain some understanding of the issue, instead of just asking for answers all the time. The dependent packages seem to depend on a single version of ghc and/or cabal-install - presumably that is correct (I don't use any haskell apps myself) but it's also the root cause of this situation.

Also, remember that updating AUR packages is entirely your responsibility.

i forgot to ignore cabal-install and only ignored ghc, but the install went through just fine as shown below:
