#9673: aarch64 7.8.4, 7.10, 7.11: lib/ghc/bin/ghc-pkg --version does not output from subprocess -------------------------------------+------------------------------------- Reporter: juhpetersen | Owner: Type: bug | Status: new Priority: high | Milestone: Component: Compiler | Version: 7.10.1-rc1 Resolution: | Keywords: Operating System: Linux | Architecture: aarch64 Type of failure: Installing GHC | Test Case: failed | Blocking: Blocked By: | Differential Revisions: Related Tickets: | -------------------------------------+------------------------------------- Comment (by rwbarton): The behavior in comment:4 is really weird, I would start the investigation there. Maybe try `echo $(strace .../ghc-pkg --version)` and try to figure out why it does not write anything to stdout? Could it be because stdout is not connected to a terminal somehow? (That's about the only explanation I can think of...) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9673#comment:12 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
