#14483: getExecutablePath from System.Environment in base should follow symlinks properly. -------------------------------------+------------------------------------- Reporter: angerman | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.6.1 Component: Compiler | Version: 8.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by angerman): Just to elaborate what is to be done here: 1. Look at `getBaseDir :: IO (Maybe String)` in `compiler/main/SysTools.hs`, and integrate the symbolic link resolution logic from there in `getExecutablePath` in the `System.Environment` Module from the `base` package. 2. If the `MIN_VERSION_base(...)` is high enough, use `getExecutablePath` also on Windows in `compiler/main/SysTools.hs`, `utils/ghc-pkg/Main.hs` and `utils/hsc2hs/Main.hs`. It looks like this should be rather easy, but requires someone with some windows exposure. Testcases in the testsuite for `getExecutablePath` would be a great bonus! -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14483#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
