#8683: add "cpp program" and "cpp program options" to settings file -------------------------------------+------------------------------------ Reporter: carter | Owner: Type: feature request | Status: patch Priority: highest | Milestone: 7.8.1 Component: Compiler | Version: 7.8.1-rc2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: #8439 -------------------------------------+------------------------------------ Changes (by carter): * status: new => patch Comment: Ok, it all works! some notes a) you still have to build using clang / gcc as the choice in cpp for GHC building, but the hooks are there to set it otherwise with --with-hs-cpp and --with-hs-cpp-flags, but various hard codings in the build system prevent ghc builds from succeeding. Its just those issue are more discoverable :-) b) ghc will correctly use the new fields in the settings file, as if invoked with -pgmP and -optP being passed in. I managed to build all of lens's deps successfully using CPPHS! I did hit a bug in CPPHS wrt building Lens 4.0.7, but again thats an issue with using CPPHS, not with the patch c) Theres still lots of hardcoded GCC / CPP things in the build system d) this gives the core of whats needed to provide a bindist that doesn't use clang/gcc for CPP, though because of other issues that need to be address (and should become a new ticket perhaps), you can't as yet build GHC with a CPP thats not clang or gcc is there any documentation i should add? (either to the places patched or the documentation somewhere in the manual / wiki) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8683#comment:42 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
