[GHC] #8270: unknown symbol "atomic_inc" in GHCi when loading package ghc
#8270: unknown symbol "atomic_inc" in GHCi when loading package ghc ----------------------------------+--------------------------------- Reporter: rwbarton | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: GHCi | Version: 7.7 Keywords: | Operating System: Linux Architecture: x86_64 (amd64) | Type of failure: None/Unknown Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | ----------------------------------+--------------------------------- I tried to do a "quick-llvm" build of a distclean-ed tree and got an error when some dph package needed to load the ghc package in Template Haskell. I no longer have that exact error message, but I could reproduce it more simply as follows: {{{ rwbarton@adjunction:~/dist/ghc4$ ./inplace/bin/ghc-stage2 --interactive -package ghc-7.7.20130910 GHCi, version 7.7.20130910: http://www.haskell.org/ghc/ :? for help Loading package ghc-prim ... linking ... done.

It's defined in libHSrts of course, but apparently not all rts symbols are automatically available in the GHCi linker? I added a {{{ SymI_HasProto(atomic_inc) \ }}} in `RTS_SYMBOLS` in `rts/Linker.c` and the problem seems to be solved. I'm not really sure what the difference between `SymI_` and `SymE_` is, it looks Windows-related. Maybe other stuff like `atomic_dec` should be added too. I'm pretty sure I didn't run into this problem with a "quick" build, though I have no idea how it could be specific to "quick-llvm". -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8270 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
