Yes, I know that the Cabal test suite wasn't passing on GHC HEAD for some time.

Re: cabal sdist trouble with GHC from head
I would imagine they are well aware, what with all the changes that have gone in the past few weeks (for backpack support, package db overhauls, etc). However, I think crux of it (and the real question) isn't are they aware - but "When will there be a Cabal release that supports GHC HEAD, which will become 7.10"? This is a question I'm afraid I cannot answer - Johan does the typical Cabal releases, AFAIK. I've CC'd Duncan and Johan - do either of you have plans for this? Considering we hope the stable freeze will happen soon for 7.10, I imagine Cabal won't be very far behind in this regard, but I'm not sure if there's a plan set down anywhere as to when the next release will happen.

OK, that's good to know. To be sure, I've just tested Cabal head + GHC 7.8.3, and it works.

I think it even supports GHC 6.12 still and Duncan tests with it. But, sometimes a GHC change may require you to use a newer version of Cabal, for things to work. So this just means that Cabal isn't necessarily *future compatible* with future GHCs - they may change the package format, etc. But it is backwards compatible with existing ones. -- Regards, Austin Seipp, Haskell Consultant Well-Typed LLP, http://www.well-typed.com/ ___ ghc-devs mailing list ghc-devs@haskell.org http://www.haskell.org/mailman/listinfo/ghc-devs

cabal has changed for HEAD, you need to install 1.21.1.0 On Thu, Oct 23, 2014 at 2:40 PM, Sven Panne wrote: > 2014-10-22 15:16 GMT+02:00 Sven Panne : > > Does anybody have a clue what's going wrong at the sdist step here? > > > >https://travis-ci.org/haskell-opengl/OpenGLRaw/jobs/38707011#L104 > > > > This only happens with a GHC from head, a build with GHC 7.8.3 is fine: > > > >https://travis-ci.org/haskell-opengl/OpenGLRaw/jobs/38707010 > > > > Any help highly appreciated... > > I would really need some help here, even adding a few more diagnostic > things to the Travis CI configuration didn't give me a clue what's > going wrong: > >https://travis-ci.org/haskell-opengl/OpenGLRaw/jobs/38813449#L110 > > I totally fail to understand why Cabal's sdist step works with every > released compiler, but not with a GHC from head.

I would really need some help here, even adding a few more diagnostic things to the Travis CI configuration didn't give me a clue what's going wrong: https://travis-ci.org/haskell-opengl/OpenGLRaw/jobs/38813449#L110 I totally fail to understand why Cabal's sdist step works with every released compiler, but not with a GHC from head. I don't even know if this is a Cabal issue or a GHC issue.

cabal sdist trouble with GHC from head
Does anybody have a clue what's going wrong at the sdist step here? https://travis-ci.org/haskell-opengl/OpenGLRaw/jobs/38707011#L104 This only happens with a GHC from head, a build with GHC 7.8.3 is fine: https://travis-ci.org/haskell-opengl/OpenGLRaw/jobs/38707010 Any help highly appreciated...
