Re: [Haskell-cafe] Cabal install fails due to recent HUnit

Hi Martijn,

Yes, upgrading will obviously fix things (we do use 0.14 on our development machines) Well, to me it wasn't entirely obvious that upgrading to Cabal-1.10.2.0 fixes the problem for cabal-install-0.12, and I still think this is a good solution for most people that use version 2012.2.0.0 of the platform.

I'd suggest you ask Duncan to patch the hackage repository, and maybe contact the maintainer of HUnit to prevent future problems. -- Martijn

, but we have not set up any infrastructure for building a custom cabal on production servers. We just use the one from the Ubuntu repositories, which uses Cabal 1.10.1.0 on oneiric. So until we upgrade to precise I guess we have a problem.

Hi Erik,

A similar thing happened to me with the GraphViz package. As Duncan explained to me, the problem is that Cabal-1.10.0.0 (and I believe also 1.10.1.0) incorrectly reports an error when conditionals are used in test suites.

Upgrading to Cabal-1.10.2.0 (or cabal-install-0.14.0 with Cabal-1.14.0) should fix the problem. Unfortunately, this means your build will not work on a fresh Haskell Platform v2012.2.0.0, until HUnit is patched in the hackage index.

Hi all,

All cabal installs using cabal-install-0.10.2 are currently failing for us. This is due to the cabal file for HUnit-1.2.5.0, which was recently uploaded to hackage. The ouput I'm getting from cabal is just:

Reading available packages... Resolving dependencies... cabal: Couldn't read cabal file "HUnit/1.2.5.0/HUnit.cabal"

If I unpack HUnit-1.2.5.0 and call 'cabal configure', I get:

cabal: HUnit.cabal:57: The 'type' field is required for test suites. The available test types are: exitcode-stdio-1.0

The relevant lines from the cabal file are:

Test-Suite hunit-tests-optimize-0 Type: exitcode-stdio-1.0

These look fine to me.

Does anyone have any idea how to go about fixing this (on hackage at least)? Could this package temporarily be removed, to avoid breaking everyone's cabal?

Erik
