g++ - G++ 4.8.1 错误：“线程”不是“标准”的成员

Question

我构建了 gcc 4.8.1 和 libstdc++.so.6.0.18，将 libstdc++.so.6.0.18 软链接到 libstdc++.so.6 我检查了 g++ -v，它是 4.8.1

test.cpp:11:9: error: ‘thread’ is not a member of ‘std’
     std::thread t(hello);

但即使是单行也无法编译..

如何解决？

总代码：

#include <iostream>
#include <thread>

void hello()
{
        std::cout<<"Hello Concurrent World\n";
}

int main(int argc, char * argv[])
{
        std::thread t(hello);
        t.join();

        return 0;
}
