My concern about the volume of warnings here is that it distracts from the info I'm after, namely broken packages. One coping strategy seems to be using the --simple-output flag to 'ghc-pkg check'. In that case, the haddock warnings are suppressed, and I see just a list of broken package names. A little terser than I'm after, but it helps. On Wed, Apr 9, 2014 at 10:53 AM, Conal Elliott wrote:

I installed the binary distribution of GHC 7.8.1 for Mac OS this morning, cabal-installed a few packages, and now I get a *lot* of warnings about missing .haddock files:

Thanks, Austin & Herbert. Switching from clang to gcc-4.8 and reinstalling libraries eliminated most of the noise for me. In one set of my own libraries (bringing in new dependencies), I did get several more haddock warnings from 'ghc-pkg check'. I reinstalled each of those libs explicitly (cabal install --reinstall --force-reinstalls), ignored the resulting warnings, and now back to a clean `ghc-pkg check`, and (so far) working packages. -- Conal On Wed, Apr 9, 2014 at 6:16 PM, Austin Seipp wrote:

Hi Conal,

Damn, I think I somehow totally missed this. :( I'll look into on my Mavericks machine and see what's going wrong - I figured ./validate would have caught this, but perhaps something strange is going on.

I filed a bug for you marked for 7.8.2: https://ghc.haskell.org/trac/ghc/ticket/8981
