#7859: runghc should give an error when the path to ghc is invalid ----------------------------------------------+----------------------------- Reporter: monoidal | Owner: Type: bug | Status: new Priority: normal | Component: None Version: 7.6.3 | Keywords: Os: Unknown/Multiple | Architecture: Unknown/Multiple Failure: Incorrect warning at compile-time | Blockedby: Blocking: | Related: ----------------------------------------------+----------------------------- runghc has a -f option which allows to specify the path to GHC. However, it uses `rawSystem` and if the path is incorrect, we only get a nonzero exit code. For example, attempting to use "ghc -fdefer-type-errors X.hs" gives absolutely no output. Attached patch uses `findExecutable` and gives an error message if the executable is not found. This is not the ideal solution, but I think it's better than the current state. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/7859 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
