#11823: Undefined stg_sel_17_upd_info symbols on OS X -------------------------------------+------------------------------------- Reporter: bgamari | Owner: Type: bug | Status: new Priority: highest | Milestone: 8.0.1 Component: Compiler | Version: 8.0.1-rc3 Keywords: | Operating System: MacOS X Architecture: x86_64 | Type of failure: Building GHC (amd64) | failed Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- Several people have reported that recent `ghc-8.0` and `master` snapshots fail to build on OS X, {{{ HC [stage 1] ghc/stage2/build/tmp/ghc-stage2 Warning: -rtsopts and -with-rtsopts have no effect with -no-hs-main. Call hs_init_ghc() from your main() function to set these options. Undefined symbols for architecture x86_64: "_stg_sel_17_upd_info", referenced from: _s1s8Z_info in UI.dyn_o _s1s9w_info in UI.dyn_o ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation) `gcc' failed in phase `Linker'. (Exit code: 1) }}} These were originally introduced in #11555, although this appears to be a much different beast from the original issue that ticket was reporting: the symbols in question here are update closures, not application closures like in #11555. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11823 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
