#15404: ghc-8.6 uninstallable on macos due to hard coded libgmp directory -------------------------------------+------------------------------------- Reporter: tmcdonell | Owner: (none) Type: bug | Status: new Priority: highest | Milestone: 8.6.2 Component: None | Version: Resolution: | Keywords: Operating System: MacOS X | Architecture: Type of failure: Installing GHC | Unknown/Multiple failed | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Changes (by berdario): * milestone: 8.6.3 => 8.6.2 Comment: Thanks to dminuoso, he pointed out that the flag is actually defined for the inner library, and in fact should be toggled differently in the build.mk While running tests with this fix in https://github.com/ghc/ghc/pull/222/files this surfaced test failures due to https://ghc.haskell.org/trac/ghc/ticket/15105 This turned out to be the same behavior in GHC 8.4, unclear why the failures weren't seen before. The .o code for the HSinteger-gmp-1.0.2.0.o had the same symbol table. The bug turned out to be in GHC static linker. We added a bunch more logging statements to the code that reads MachO symbols. It turned out that it was counting the number of external symbols (let's say M), and then going through the first M such symbols in the table (thus ignoring the last N-M symbols). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15404#comment:12 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
