#8683: add "cpp program" and "cpp program options" to settings file -------------------------------------+------------------------------------ Reporter: carter | Owner: Type: feature request | Status: patch Priority: normal | Milestone: 7.8.1 Component: Compiler | Version: 7.7 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: #8439 -------------------------------------+------------------------------------ Comment (by carter): OK, theres several things going on here, and i'm going to lay it out so i can be less confused (and hopefully i can understand your ideas better), and perhaps you can be less confused to! (though you are pointing out a real bug i think too) 1) theres currently (and unfortunately), some places in the build system where GCC is hard coded. a) historically the only C compiler GHC would support was GCC. thus historically --with-gcc was just a way of picking which gcc to use system with more than one gcc installed (I think, i could be wrong here) b) the clang support for ghc is pretty recent, and theres definitely a few corners that still need cleanup the CPP mode for Haskell code is always "traditional mode", so the flags passed to haskell CPP != the flags passed to C, though there may be some overlap -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8683#comment:24 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
