关于使用GCC编译C++程序的问题

wuyougan

我第一次使用GCC编译C++，出现如下问题。

源码：
[code:1]#include <iostream>
using namespace std;
main (void) {
    cout<<"test."<<endl;
}
[/code:1]

使用GCC a.cpp后，出现如下提示：
[code:1]linux:~# gcc a.cpp
/tmp/ccS6U07q.o(.text+0x1b): In function `main':: undefined reference to `std::cout'
/tmp/ccS6U07q.o(.text+0x20): In function `main':: 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*)'

/tmp/ccS6U07q.o(.eh_frame+0x11): undefined reference to `__gxx_personality_v0' collect2: ld returned 1 exit status[/code:1]

不知道在使用GCC编译C++时，要不要外加参数？

用g++编译c++程序，用gcc编译c程序。

终于明白了，谢谢。

编译完后怎么执行？？
