我升級到了maverics，現在boost-python的macports版本不起作用。在小牛隊上由macports安裝的boost-python鏈接錯誤
我安裝了ports：gcc48和boost + python33。
我試圖編譯該程序用C++ 11或不具有C++ 11：
#include <boost/python.hpp>
class A {};
BOOST_PYTHON_MODULE(libblah) {
boost::python::class_<A>("A");
}
我用cmake的，但所產生的構建命令低於與所述接頭沿錯誤，我得到：

我該如何解決這個bug而不用自己安裝boost。與此Related question，在圖書館
nm libboost_python-mt.dylib | c++filt | grep boost::python::objects::function_object
符號中發現：
0000000000013d60 T boost::python::objects::function_object(boost::python::objects::py_function const&)
0000000000013d00 T boost::python::objects::function_object(boost::python::objects::py_function const&, std::__1::pair<boost::python::detail::keyword const*, boost::python::detail::keyword const*> const&)
然而，他們的std :: __ 1前綴不匹配什麼是在未定義符號的錯誤預期。
