#13217: configure script uses different CFLAGS from the actual build -------------------------------------+------------------------------------- Reporter: dobenour | Owner: Type: task | Status: new Priority: normal | Milestone: Component: Build System | Version: 8.1 Resolution: | Keywords: autoconf Operating System: Unknown/Multiple | Architecture: Type of failure: Building GHC | Unknown/Multiple failed | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by rwbarton): Could you be more specific? There are various sets of flags and even potentially multiple C compilers that will be used at different points during the build of GHC. And in the instance in Phab:D2996, it looks like the failure occurred while compiling the RTS; but `-Werror` was in effect only because this was part of a validate build. More generally the user can specify additional options for building the RTS via the make variable `GhcRtsCcOpts`, and we can't know the value of that variable at configure time. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13217#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
