Replying to [comment:22 parcs]:

Is there some way to detect whether GHC has support for parallel `--make`? E.g. using `ghc --info`? I'd prefer to use that instead of conditioning on the version.

What are the advantages of adding an entry to `ghc --info` over conditioning on the version, in this case? ---- GHC no longer deadlocks from its use of `setNumCapabilities` (see #8209) but there is still another related issue: GHC sometimes prints {{{ ghc-stage2: GHC.Event.Manager.loop: state is already Finished }}} when exiting. See #8235 ---- Ryan: That's really odd. I'm going to try `cabal install -j` with my branch later today and let you know how it goes. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/910#comment:48 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
