#15040: DTrace enabled GHC does not work as a bootstrap compiler on FreeBSD -------------------------------------+------------------------------------- Reporter: raichoo | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.4.2 Component: Build System | Version: 8.4.1 Keywords: dtrace | Operating System: FreeBSD Architecture: | Type of failure: Building GHC Unknown/Multiple | failed Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- GHC 8.4.1 enables DTrace probes on FreeBSD. This currently causes issues with the using such compilers as a bootstrap compiler for building GHC itself due to the way linking of the RTS is handled. I didn't encounter any issues regarding daily use on FreeBSD but suspect it might cause problems with user defined hooks. Current workaround is to build a version of GHC with DTrace disabled and use that as a bootstrap compiler. A patch has been merged into HEAD. I've already tested it in combination with 8.4.2-rc1 and it worked fine. https://phabricator.haskell.org/rGHC4b831c27926d643b0b6fad82c1e946d05cde8645 I have an idea on how to fix this but haven't had the time to put that plan into action. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15040 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
