#13007: ghc-options -threaded present but -N option unrecognised on ARM -------------------------------------+------------------------------------- Reporter: tmpz | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Runtime | Version: 8.0.1 System | Keywords: arm, | Operating System: Linux raspberrypi, raspbian, rts, | threaded | Type of failure: Incorrect result Architecture: arm | at runtime Test Case: | Blocked By: http://allocinit.io/haskell | /haskell-on-raspberry-pi-3/ | Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- When compiling a program on ARM (Raspberry PI 3, OS: Raspbian Jessi) with ghc it is possible to specify as runtime options {{{ -threaded -rtsopts -with-rtsopts=-N }}} However when running the program with -N, -N is not a recognised option. See output here http://pastebin.com/sKjfkRtq Running with --info gives the following http://pastebin.com/q36Ef7y4 showing that ("RTS way", "rts_thr") is available. Investigation already done here: https://www.reddit.com/r/haskell/comments/5j0u36/getting_haskell_and_stack_o...

Confusing I know! The build system was accidentally disabling SMP for all ARM builds, even when targeting a version of ARM that supports the atomic operations needed to support multiprocessing. Recently reported and fixed in #12981. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13007#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
