#9823: --show-iface panics with HEAD -------------------------------------+------------------------------------- Reporter: jstolarek | Owner: Type: bug | Status: closed Priority: normal | Milestone: 7.12.1 Component: Driver | Version: 7.9 Resolution: duplicate | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: GHC doesn't work | Unknown/Multiple at all | Test Case: Blocked By: | Blocking: Related Tickets: #9963 | Differential Revisions: -------------------------------------+------------------------------------- Changes (by thomie): * status: new => closed * resolution: => duplicate * related: #9799 => #9963 Comment: Closing this as a duplicate of #9963, for which I have a fix. '--show-iface' is a mode flag, just like '--interactive' and '-e', and all usages of invalid (combinations of) mode flag(s) currently panic in HEAD. Note that the filename should come after the flag, and the error is: {{{ $ ghc-7.8.4 T9963.hi --show-iface ghc: on the commandline: missing argument for flag: --show-iface Usage: For basic information, try the `--help' option. }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9823#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
