Mavericks

[Jeremy Huddleston Sequoia]

Apple released Mavericks today, and MacPorts works great on the new OS (assuming you use trunk/base).

However, there is one big change that I want to point out to other MacPorts developers: the C++ runtime.

The default C++ runtime is now libc++.  libstdc++ is still available for binary compatibility, but newly built applications and frameworks should use libc++.  This means that clang++ should be used for all C++ code since g++ does not support libc++.  If a port uses C++ and fails to build with clang, it will not be supported on Mavericks (unless it does not export nor utilize C++ APIs to/from other ports).

At this point, most C++ ports "just work" with libc++, so most users will be able to install their ports on Mavericks.  One of the main reasons ports fail to build with libc++ is the tr1 namespace.  If you see build errors about missing tr1 headers, please see this website for information:
http://cplusplusmusings.wordpress.com/2013/06/03/whats-up-with-tr1-and-c11-and-libc/

Here is the list of ports which are currently listed as not working on Mavericks (mainly due to C++ issues).  If you need any of these ports, please work with maintainers and developers to address the issues.
