cannot find normal object file #1266

UnkindPartition · 2013-04-12T09:51:05Z

I cannot build traverse-with-class with GHC 7.7.20130407. Following #1207, I built Cabal master (which includes Mikhail's patch), but I get the same error:

Yes, I haven't tested with GHC 7.7. Unfortunately, I don't have time to do it right now.

Related: #1252.

23Skidoo · 2013-07-11T01:56:22Z

Tried building traverse-with-class with Cabal HEAD and GHC HEAD. Works fine for me.

23Skidoo · 2013-07-12T15:55:15Z

Should be fixed in HEAD. Please reopen if this still happens.

Fuuzetsu · 2013-08-31T19:22:36Z

This seems to still be broken. We can not run Template Haskell HTML tests in Haddock through cabal. It works just fine if you run these files directly using Haddock.

I'm getting the following error while trying to build haddock:

Does this mean I need a more recent GHC HEAD snapshot?

23Skidoo · 2013-09-01T16:14:41Z

Aha, this was a recent change: ghc/haddock@34d2aa5

Fixed by reverting to ghc/haddock@9f356e8.

23Skidoo · 2013-09-01T16:20:41Z

OK, have to run, will finish later.

Fuuzetsu · 2013-09-01T19:45:54Z

That means your GHC was too old. We tightly couple with GHC API. The error should persist with older Haddock so it should persist with your revert.

23Skidoo · 2013-09-01T22:22:08Z

@Fuuzetsu

OK, now I am getting

when trying to run cabal test.

Any idea how to fix this?

23Skidoo · 2013-09-01T22:35:52Z

Managed to reproduce this with traverse-with-class:

Fuuzetsu · 2013-09-01T23:24:52Z

Ah, that old error. I don't remember the fix but I'm glad that you managed to reproduce on traverse. I suggest you use that for testing as Haddock behaviour depends heavily on the GHC you're using &c which is hard to control and reproduce.

23Skidoo · 2013-09-02T23:59:22Z

@Fuuzetsu

This problem is caused by the fact that when GHC is dynamic-by-default, the modules loaded during the TH phase must use the same ABI. That's why it complains about the missing .dyn_o. So the error can be fixed by passing --haddock-options=--optghc=-dynamic-too to cabal haddock.

To fix this in Cabal, we need to be able to find out whether the GHC that haddock is compiled with is dynamic-by-default (i.e. get the ghc --info output). Perhaps we can query the GHC that we were configured with.

However, wouldn't it be better to fix Haddock itself to produce .dyn_o when the GHC it is linked against is dynamic-by-default? This can be done by passing -dynamic or -dynamic-too (when it's supported) to GHC. That way, haddock will still work for libraries that use TH when run in standalone mode (i.e., not driven by Cabal).

Fuuzetsu · 2013-09-03T02:14:17Z

Unfortunately I'm unsure how this would look on our end, ping @sol for input on this.

23Skidoo · 2013-09-03T13:54:27Z

@Fuuzetsu

You need to parse the output of ghc --info, and if GHC itself uses dynamic linking (there's a ("GHC Dynamic","YES") tuple in the output), you should pass GHC the -dynamic option so it generates .dyn_o instead of .o. If GHC supports -dynamic-too, you can also use that instead.

23Skidoo · 2013-09-03T14:25:43Z

Created a ticket on the Haddock bug tracker.

tibbe · 2013-09-03T14:59:30Z

Can this be postponed to after 1.18?

23Skidoo · 2013-09-03T15:10:54Z

@tibbe Yes, and I think we can actually close this ticket since it's a Haddock issue.

@Fuuzetsu Please reopen if you disagree.

Fuuzetsu · 2013-09-03T20:37:58Z

Alright, thanks for looking into it!

UnkindPartition · 2013-10-24T14:13:57Z

Hmm, I'm still getting the exact same error with Cabal & cabal-install from git master, and ghc-7.7.20131012.

@feuerbach
What is the output of ghc --info on your machine?

UnkindPartition · 2013-10-24T14:33:07Z

I found what triggers the bug. It's shared: False in my ~/.cabal/config. If I change it to shared: True, it installs fine.

23Skidoo · 2013-10-24T14:41:31Z

That makes sense. I'll investigate why the value of shared is not ignored in this case (as it should be).

23Skidoo · 2013-10-24T14:49:42Z

@feuerbach

You need to add default-extensions: TemplateHaskell to the library stanza. Then it will work even with shared: False in .cabal/config. Otherwise, Cabal has no way to detect that Template Haskell is used.

UnkindPartition · 2013-10-24T15:55:53Z

That worked (even with other-extensions), thank you!

23Skidoo · 2013-10-24T16:01:14Z

Hmm, yes, other-extensions is more appropriate here.
