gcc编译错误,在Visual Studio 2008 C++中正常工作

Question

在gcc中获取编译错误,即使它在Visual Studio C++上正常工作

#include <iostream>
using std::cout;  // tried it, didn't work
using std::cin;   // tried it, didn't work
using std::endl;  // tried it, didn't work

using namespace std;

这是错误,我在尝试编译它时得到了.

hw2_part2.cpp:(.text+0xa2): undefined reference to `std::cout'
hw2_part2.cpp:(.text+0xa7): undefined reference to `std::basic_ostream<char, std::char_traits<char> >& std::operator<< <std::char_traits<char> >(std::basic_ostream<char, std::char_traits<char> >&, char const*)'

使用g++而不是编译来编译gcc链接的C++库.

看看gcc和g ++/gcc-c ++有什么区别？如果你有兴趣可以获得更多细节(虽然它真的不多).
