Description Enji Cooper freebsd_committer 2014-10-08 23:31:53 UTC
CSTD sets -std= in CFLAGS, but not CXXFLAGS. It should do it for both (the reason why I didn't commit a change immediately is that it requires discussion and testing via a ports tinderbox).

Since the standard names for C and C++ are different, you cannot really use the CSTD variable.  I would suggest using CXXSTD, which is consistent with all the other "CXX" prefixes.

The available options should probably be:
* c++98
* gnu++98
* c++03
* gnu++03
* c++0x
* gnu++0x
* c++11
* gnu++11
* c++1y
* gnu++1y
* c++14    (these are only available from clang 3.5 and higher)
* gnu++14

Although the usefulness of the 03, 0x and 1y 'standards' is debatable, at least for the base system.  For ports, all of these should obviously be available.
