Unless Gyoto does not exchange C++ objects with any other code, in which case you could set configure.cxx_stdlib to libc++ on 10.6+ and depend on libcxx. If it does exchange C++ objects with other code, you *cannot* safely change cxx_stdlib in the port, you have to keep its global value and enable or disable C++11 accordingly. - Josh _______________________________________________ macports-dev mailing list [email protected] https://lists.macosforge.org/mailman/listinfo/macports-dev
