#7992: Wrong invocation of configure script in libffi and integer-gmp ---------------------------------+------------------------------------------ Reporter: merijn | Owner: Type: bug | Status: patch Priority: normal | Milestone: Component: Build System | Version: 7.7 Keywords: patch | Os: Unknown/Multiple Architecture: Unknown/Multiple | Failure: Building GHC failed Difficulty: Unknown | Testcase: Blockedby: | Blocking: Related: | ---------------------------------+------------------------------------------ Comment(by merijn): This is not about the generated configure script, it's an upstream issue with the behaviour of autoconf. Autoconf tries to determine the location from which a configure script is run and then set paths based on that. Due to the behaviour I described, running configure without the ./ and another configure script *anywhere in your path* will lead autoconf to conclude that configure is being run from *within that directory on your path*. This of course leads it to refer to all sorts of wrong paths. This change makes autoconf decide to check the current working directory for the location of the configure script before it tries looking in your path, as a result it uses the correct directory even if there's another configure script in your path anywhere. The output of "make show VALUE=SHELL" should be irrelevant, but is: {{{ make -r --no-print-directory -f ghc.mk show SHELL="/bin/sh" }}} -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/7992#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
