Friends

Can anyone help Kathleen out?  She has a cabal-install issue.  I think she’s on a Mac.

Many thanks

Simon

Subject: Fwd: Installing syb(-0.1.03) package in head version of Haskell

Hi Simon,

I'm trying to get the PADS file we were working on compiling under the HEAD version of Haskell, but I'm having trouble getting the Data.Generics module to install. I sent the question below to the libraries@haskell.org last week, but I haven't seen any replies.  Is that the right address?  Or is there a different place to ask such questions?

Thanks for any pointers!

Kathleen

Subject: Installing syb(-0.1.03) package in head version of Haskell

Hi all,

I'm trying to get a program that uses the Data.Generics module to compile under the head version of GHC, but I am having trouble getting the syb package installed.  

I believe I am using the most recent version of cabal:

kfisher-laptop:/Users/kfisher/pads/dirpads/language-c-quote>~/.cabal/bin/cabal --version

cabal-install version 0.8.0

using version 1.8.0.1 of the Cabal library

When I ask cabal to install the syb package, I get the following error:

kfisher-laptop:/Users/kfisher/pads/dirpads/language-c-quote>~/.cabal/bin/cabal install -w ~/sw/ghc-head/bin/ghc

syb-0.1.0.3 failed during the building phase. The exception was:

The full trace is included below.

Here's the version information for the ghc I am running.

Kfisher-laptop:/Users/kfisher/pads/dirpads/language-c-quote>~/sw/ghc-head/bin/ghc --version

The Glorious Glasgow Haskell Compilation System, version 6.13.20100210

The cabal website suggests sending questions to this list...

Any suggestions for how to fix this problem?
