That looks very strange. Can you reproduce it consistently?

ghc obviously compiled a source file:
> [41 of 41] Compiling Documentation.Haddock ( src/Documentation/Haddock.hs, dist/build/Documentation/Haddock.o )

It should have been created Haddock.o Haddock.hi Haddock.dyn_o Haddock.dyn_hi.
Do you have it there?

[Comment 2 Alexander Vershilov (RETIRED) 2014-12-30 13:26:18 UTC]

Seems this issue related to upstream one https://ghc.haskell.org/trac/ghc/ticket/9176

and it is not solved yet. For me dyn_hi is not created for an 'empty' modules that have only reexports, like this one in haddock.

Yes. Tried 4 times.

Yes, I have Haddock.o Haddock.hi and Haddock.dyn_o in $S/dist/build/Documentation. The full /var/tmp/portage/dev-haskell/haddock-2.14.3.0.7.8.3 dir tree is attached.

Interesting, you have a single .dyn_hi file there.
Looks suspiciously like ghc bug Alexander pointed to.

I wonder why I can't reproduce it. Let's try two tests:

1. try to reproduce with MAKEOPTS=-j1 (it will make build more deterministic)
2. try to build with HCFLAGS="-O -v" and attach build.log here. It will increase verbosity of compiler.

verbose build log

(In reply to Sergei Trofimovich from comment #4)

Build log with HCFLAGS="-O -v" MAKEOPTS=-j1 attached.

[Comment 6 Alexander Vershilov (RETIRED) 2014-12-30 23:53:56 UTC]

As Mark Wright says you rebuilding *ghc* with MAKEOPTS=-j1 or using USE="binary" fixes the issue, currently I'm trying to rebuild my system and understand if it will save me. I'm also experience same issue but with a different set of packages.

[Comment 7 Alexandre Rostovtsev (RETIRED) 2014-12-31 02:43:10 UTC]

(In reply to Alexander Vershilov from comment #6)

Interesting, rebuilding ghc with MAKEOPTS=-j1 (and then rebuilding cabal and ghc-paths) did fix the problem. Unfortunately, with -j1 compiling ghc takes almost 70 minutes.
