在OS X下提升編譯錯誤10.8.5

Question

我嘗試使用Boost庫版本1.34.1在Mac OS X 10.8.5下編譯項目時出現問題。我正在使用Xcode 4.6.3和附帶的命令行工具。這必須是OS X特定的問題，因爲項目在CentOS Linux下編譯。

我在這裏問這個，希望有人在OS X開發中使用了Boost，可能會遇到類似的問題。

我附上了下面編譯器消息的摘錄。我試着用Google搜索這個錯誤，但似乎找不到滿意的答案。請讓我知道你是否可以想到一些事情，如果你需要更多的信息（例如源代碼摘錄）能夠幫助我，那麼更有可能。

非常感謝你，

最佳，

塞巴斯蒂安

編輯：我注意到，boost/functional/hash/hash.hpp包括以下內容：

#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 

如此看來，在類型的定義在那裏，但不適用於我的系統。這有任何意義嗎？我可以繞過這個嗎？

Answer 1

它基本上說在hash.hpp中有很多hash_value函數，但它們都不適用於散列表中的類型（顯然是long long）。

您的工具對於該類型來說太舊了，或者您沒有編譯時使用適合編譯器的-std=...參數。
