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

[Simon Peyton-Jones]

Friends

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

Many thanks

Simon

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 at haskell.org<mailto:libraries at 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

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

language-c-quote-0.1 depends on syb-0.1.0.3 which failed to install.
syb-0.1.0.3 failed during the building phase. The exception was:
exit: ExitFailure 1


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?

Kathleen
