C++ 编译器无法识别 std::stringstream::swap

Question

我正在尝试使用 g++ (GCC) 4.8.2 20131212 (Red Hat 4.8.2-7) 编译以下代码:

#include <sstream>
using namespace std;

int main(int argc, char ** argv)
{
    auto x = 1;
    stringstream s1, s2;
    s1.swap(s2);
}

我收到以下错误:

g++ -g -std=c++0x -c main.cpp
main.cpp: In function ‘int main(int, char**)’:
main.cpp:8:5: error: ‘std::stringstream’ has no member named ‘swap’
  s1.swap(s2);
     ^
make: *** [main.o] Error 1

根据 this reference它应该工作。使用不同的 -std 标志(gnu++11、c++0x 等)没有帮助。我错过了什么？

Answer 1

从GCC实现状态看:

Section: 27.5
Description: Iostreams base classes
Support: Partial
Comments:

• Missing move and swap operations on basic_ios.
• Missing io_errc and iostream_category.
• ios_base::failure is not derived from system_error.
• Missing ios_base::hexfloat.
