#8641: ghc with -odir and -prof cannot create the specified output directory -----------------------------------+--------------------------------------- Reporter: wmarshall | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.6.3 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: Compile-time crash Unknown/Multiple | Test Case: Difficulty: Unknown | Blocking: Blocked By: | Related Tickets: | -----------------------------------+--------------------------------------- Calling ghc with -odir set to a non-existent directory causes ghc to create the directory. However, if the -prof option is also specified, ghc fails to create the directory and quits with an error. Steps to reproduce: {{{ $ echo 'main = print "Hello world"' > Main.hs $ ghc Main.hs -odir bin [1 of 1] Compiling Main ( Main.hs, bin\Main.o ) Linking Main.exe ... $ rm -Rvf bin removed `bin/Main.o' removed directory: `bin' $ ghc Main.hs -odir bin -prof [1 of 1] Compiling Main ( Main.hs, bin\Main.o ) C:/Program Files (x86)/Haskell Platform/2013.2.0.0/mingw/bin/ld.exe: cannot open output file bin\Main.o: No such file or directory collect2: ld returned 1 exit status }}} Expected result: The output directory is created regardless of whether -prof is specified. The above commands were executed from within Cygwin, but the error occurs in the Windows command shell as well. (I used Cygwin here because it is easier to give precise instructions to reproduce the error.) I have only tested this on Windows. I do not know if the issue exists on Linux or other platforms. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8641 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
