In the recent mailing list discussion on C++11, there were no comments on the specific aspects of the proposal
There is one aspect in particular that I would like to ask about: the proposed changes to clang (https://trac.macports.org/ticket/53194).
Any comments would be greatly appreciated.
There are three ways to allow clang to refer to MacPorts libstdc++.
1) Create a *default* variant to have -stdlib=libstdc++ refer to MacPorts libstdc++.
This was quite rightly rejected because clang should be “as compatible with the host as possible.”
I only bring it up because the required patch is simpler.
2) Create a new command switch -stdlib=macports-libstdc++ to refer to MacPorts libstdc++.
3) Create a new subport clang-libstdcxx for which -stdlib=libstdc++ refers to MacPorts libstdc++.
Again, a reason to do this is because the required patch is simpler.
#2 is already in the development versions of clang
but for my purposes, the variant would have to be the default.
Patches for all three proposal are attached to the ticket.
