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:

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.

Does that really use the character '*' ? That's pretty weird. Max, are you getting the same? We'll need some help working out where that '*' is coming from.

Yikes — I just checked what Gmail sends as the plain-text alternative with an HTML email, and it does indeed use asterisks. Many people have their email clients set to show only the plain-text version of any email they get, so it's probably best to always use plain text in the first place for technical discussions. ^_^ _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

Please file a ticket in the ghc trac with as much detail as is necessary for someone else to reproduce this.

Given what we have at the moment I cannot see the cause of the problem.

From what you've pasted we can see that Cabal is only calling hsc2hs with a single -o flag and yet hsc2hs is complaining that we're passing it multiple -o flags.

No, that's one -o flag and a single additional non-flag argument which is the input file. It's like:

$ command input -o output

but with the order reversed as:

$ command -o output input

Oh! I was pretty sure that I made these patches correctly. But guess what, the added flags to hsc2hs are different from the others. And I did a bling copy/paste. Thanks for reminding it Gregory. Best, 2010/1/6 Gregory Collins
