#98: cabal assumes -x option for linking ---------------------------------------+------------------------------------ Reporter: Christian.Maeder@dfki.de | Owner: ijones Type: defect | Status: closed Priority: normal | Milestone: Cabal-1.2 Component: Cabal library | Version: 1.2.0 Severity: normal | Resolution: fixed Keywords: | Difficulty: easy (<4 hours) Ghcversion: 6.6 | Platform: Other Unix ---------------------------------------+------------------------------------ Comment (by duncan): Replying to [comment:16 guest]:

We have Solaris 10, you're program outputs the value 1048320, too. However, my problem was about the xargs -s value. So draw your own conclusions from my output below. Cheers Christian

Thanks very much Christian, that's great. I don't think us cabal hackers realised it was just `xargs` the unix program that had the limit and assumed it was the process limit. There's also an `xargs` function in cabal and we mistakenly applied the limit to that too: {{{ Thu Oct 18 15:05:00 BST 2007 Simon Marlow <simonmar@microsoft.com> * FIX GHC bug #1785: use 2048 as the maximum command-line size Apparently Solaris sets a limit of 2048 here hunk ./Distribution/Simple/GHC.hs 411 - maxCommandLineSize = 30 * 1024 + -- used to be 30k, but Solaris needs 2k (see GHC bug #1785) + maxCommandLineSize = 2048 hunk ./Distribution/Simple/GHC/Makefile.in 62 - (echo $(C_OBJS) `$(MKSTUBOBJS)`; find $(patsubst %.$(osuf),%_split,$(HS_OBJS)) -name '*.$(way_)o' -print) | xargs -s 30000 $(AR) q $(EXTRA_AR_ARGS) $@ $ + (echo $(C_OBJS) `$(MKSTUBOBJS)`; find $(patsubst %.$(osuf),%_split,$(HS_OBJS)) -name '*.$(way_)o' -print) | xargs -s 2048 $(AR) q $(EXTRA_AR_ARGS) $@ $ }}} (Simon later applied another patch to remove the `-s` arg from the `xargs` program invocation) So I'll change `maxCommandLineSize` back to 30k which seemed to be ok previously. I'm leaving the call to the `xargs` program well alone. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/98#comment:17> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects
