C++ 无法解析std:：to_string（）

虽然其他C++11表达式正在正常运行，但我有一个错误“Function”to_string“clould not resolved”。我在LinuxMint上使用EclipseMarsCDT和GCC-C++4.9

#include <iostream>
#include <string>

using std::string;

int main()
{
    int a = 123;
    string str = std::to_string(a);
}

#包括
#包括
使用std:：string；
int main（）
{
INTA=123；
字符串str=std:：to_字符串（a）；
}

是的，我使用了-std=c++11、-uuuuugxx\u EXPERIMANTAL\u CXX0X\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu！使用std:：string后的冒号是什么？请用一个或@NathanOliver来回答你的问题好吧，我纠正了这个小错误。

-std=c++11

足够好了-不要用“\uuuugxx\u EXPERIMANTAL\u CXX0X\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu。他们不能使用c++11，这也会导致此问题。@NathanOliver它至少标记了c++11，并在问题中指定了其他c++11表达式正在工作是的，它标记为c++11，但如果它们没有使用

-std=c++11

编译，那么这就是答案，您的答案将是错误的。@NathanOliver注意到他指定的其他c++11表达式正在运行OP添加了代码，看起来这两个问题都解决了。
