Trouble using cabal install with 7.8.2

[Stephen J. Barr]

Greetings,

I am working on my first .cabal file for a project I am working on. I am working in a sandbox, and I have installed the following set of packages using cabal install (in that order):

syb, either-unwrap , roots , uuid , random-fu , monad-par

When trying to do cabal install repa, I get this output:

------------------------------------

$ cabal install repa

Dependency tree exhaustively searched.

Note: when using a sandbox, all packages are required to have consistent

dependencies. Try reinstalling/unregistering the offending packages or

recreating the sandbox.

-------------------------------------

However, if I clone the repa repository, cd repa/repa && cabal install, that seems to work.

As I said, I am new to cabal. Is there something I am doing wrong or is there a dependency issue that has not been worked out in the switch to GHC 7.8.2?

Thanks!

It looks like repa on hackage has a restriction to base of 4.6.0.0 but ghc 7.8 only supplies 4.7.0.0. The git version relaxes the restriction so the install works. I assume that the repa maintainers will release a new version on hackage to address this.

[Ben Lippmeier]

Yeah, the Hackage version only works with GHC 7.6. 

This is on my list of things to fix... pending.

Ben.
