From: Jeremy Huddleston Sequoia [[br]] Subject: gcc support for larger deployment targets [[br]] Date: June 4, 2014 at 12:01:42 AM CDT [[br]] To: Markus Weissmann, David Evans, Ryan Schmidt

Could one of you please update the gcc ports to support deployment targets >= 10.10?

I suggest that you just make this change in gcc47, gcc48, and gcc49 and mark gcc46 and earlier as not supported on Yosemite, since upstream no longer supports gcc-4.6.

{{{ $ gcc-mp-4.8 -mmacosx-version-min=10.12.13 -dM -E -o - - < /dev/null | grep MAC_OS_X <built-in>:0:0: error: unknown value '10.12.13' of -mmacosx-version-min #define __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__ 1000 }}}

{{{ $ clang-mp-3.4 -mmacosx-version-min=10.12.13 -dM -E -o - - < /dev/null | grep MAC_OS_X #define __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__ 101213 }}}

See r120636, [browser:trunk/dports/lang/llvm-3.4/files/yosemite- deployment-target.patch@120636 dports/lang/llvm-3.4/files/yosemite- deployment-target.patch] as reference.

Thanks, [[br]] Jeremy
