当我尝试包含字符串时，我目前正在 Xcode 上开发
#include <string>
一切都很好，但是当我包含 CryptoPP 标头时，其中包括<string>
#include "integer.h" //integer.h have #include <string> in it
编译时出现以下错误
bits/basic_string.tcc:63:11: Cannot define or redeclare '_S_max_size' here because namespace '_STL' does not enclose namespace '_Rep'
bits/basic_string.tcc:63:28: Use of undeclared identifier 'npos'; did you mean 'fpos'?
bits/basic_string.tcc:63:28: Use of class template fpos requires template arguments

bits/basic_string.tcc:100:9: Use of undeclared identifier '__end'
bits/basic_string.tcc:100:9: Use of undeclared identifier '_Rep'
等等...
这是系统头文件中的一些错误还是编译器中的错误？我正在使用 Apple LLVM 4.2（我需要使用它）
