#9213: Maybe important CPP warnings on ghcautoconf.h from cpphs -------------------------------------+------------------------------------- Reporter: asr | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.3 Resolution: | Keywords: Differential Revisions: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: Difficulty: Unknown | Blocking: Blocked By: | Related Tickets: | -------------------------------------+------------------------------------- Changes (by asr): * version: 7.8.2 => 7.8.3 Old description:
The cpphs program yields the following warning:
{{{ Warning: trailing characters after #if directive in file ... /ghcautoconf.h at line 383 col 1: AC_APPLE_UNIVERSAL_BUILD }}}
I guess it is necessary to replace `#if defined` by `#ifdef` in the line {{{ #if defined AC_APPLE_UNIVERSAL_BUILD }}} from the mk/config.h.in file.
Note the next line `# if defined __BIG_ENDIAN__` has the same issue.
New description: cpphs 1.18.5 yields the following warning: {{{ Warning: trailing characters after #if directive in file ... /ghcautoconf.h at line 383 col 1: AC_APPLE_UNIVERSAL_BUILD }}} I guess it is necessary to replace `#if defined` by `#ifdef` in the line {{{ #if defined AC_APPLE_UNIVERSAL_BUILD }}} from the mk/config.h.in file. Note the next line {{{ # if defined __BIG_ENDIAN__ }}} has the same issue. -- -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9213#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
