我有一个问题，试图在Mac OS X 10.8.5下使用Boost库，版本1.34.1编译一个项目。我使用Xcode 4.6.3和随附的命令行工具。这一定是OS X特有的问题，因为该项目是在CentOS Linux下编译的。
我在这里问这个问题，希望有人在OS X开发中使用Boost，并且可能遇到类似的问题。
我在下面附上了编译器消息的摘录。我试着在谷歌上搜索这个错误，但似乎找不到令人满意的答案。请让我知道，如果你能想到的东西从你的头顶或，这是更有可能的，如果你需要更多的信息(例如，源代码摘录)，能够帮助我。
非常感谢，

编辑:我注意到boost/functional/hash/hash.hpp包括以下内容:
#if defined(BOOST_HAS_LONG_LONG) && defined(_M_X64) && defined(_WIN64)
// On 64-bit windows std::size_t is a typedef for unsigned long long, which
// isn't due to be supported until Boost 1.35. So add support here.
// (Technically, Boost.Hash isn't actually documented as supporting
// std::size_t. But it would be pretty silly not to).
std::size_t hash_value(long long);
std::size_t hash_value(unsigned long long);
#endif
所以似乎类型的定义是存在的，但在我的系统中不可用。这说得通吗?我能绕过这个吗?
它基本上说在hash.hpp中有很多hash_value函数，但它们都不适用于哈希表中的类型(显然是long long)。
您的工具对于该类型来说太旧了，或者您没有为编译器使用适当的-std=...参数进行编译。
