#14444: Linker limit on OS X Sierra breaks builds for big projects -------------------------------------+------------------------------------- Reporter: dredozubov | Owner: angerman Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.2.1 (Linking) | Resolution: | Keywords: Operating System: MacOS X | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by angerman): So I believe this was mitigated in stack one way or the other; but your ticket commercialhaskell/stack#2577 makes it seem like it isn't. In cabal it is mitigated by haskell/cabal#4656. I guess we should just go ahead and fix it properly in GHC. I feel GHC should fall over quicker if you construct a massive dependency tree with long folder and library names. Of course now that most people using cabal, nix or stack don't hit this issue anymore as hard, the pressure to fix this is not as high anymore. If you as such can reproduce a sample that always fails (it might be sufficient to double your dependencies)that would be helpful. Note however: we will not be able to fix this for the case where all dependencies are direct, without some heavier lifting. IOW if it's the indirect (transitive) dependencies that cause the blow up, we might be able to fix that rather easy. If it is the direct dependencies that cause the blow up, this will pose a harder problem as we'd have to potentially inject pseudo aggregation libraries, which I'd rather not do. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14444#comment:10 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
