Re: [Haskell-cafe] Problem with cabal install zlib

I actually ran into this problem last night. Here's my workaround (note that it involves downgrading to zlib-0.5.0.0 1) unregister the zlib-0.5.2.0 package (prompt> ghc-pkg unregister zlib-0.5.2.0) 2) rebuild and install cabal-install: prompt> tar -zxvf ~/.cabal/packages/hackage.haskell.org/cabal-install/0.6.4/cabal-install-0.6.4.tar.gz prompt> cd cabal-install-0.6.4 prompt> runghc Setup.hs configure --user && runghc Setup.hs build && runghc Setup.hs install Note that this requires that you still have zlib-0.5.0.0 installed. Also your paths and options for configuring may vary. But, this worked for me. Max On Dec 19, 2009, at 5:39 PM, Ozgur Akgun wrote:

Thanks for the feedback.

I guess the following part is the problematic part: (But I've no idea how to resolve it)

Hi,

When I run cabal install zlib or cabal upgrade zlib I get the following error:

Resolving dependencies... Configuring zlib-0.5.2.0... Preprocessing library zlib-0.5.2.0... Only one output file may be specified

We'll need more details here. Try running with -v2 or -v3. It should say what command it's running.
