使用 gcc 编译 C++ 程序

Question: How to compile a C++ program with gcc compiler?

信息.c:

#include<iostream>
using std::cout;
using std::endl;
int main()
{
   #ifdef __cplusplus
   cout << "C++ compiler in use and version is " << __cplusplus << endl;
   #endif
   cout <<"Version is " << __STDC_VERSION__ << endl;
   cout << "Hi" << __FILE__ << __LINE__ << endl;
}

当我尝试编译 info.c

$ gcc info.C

Undefined                       first referenced
 symbol                             in file
cout                                /var/tmp/ccPxLN2a.o
endl(ostream &)                     /var/tmp/ccPxLN2a.o
ostream::operator<<(ostream &(*)(ostream &))/var/tmp/ccPxLN2a.o
ostream::operator<<(int)            /var/tmp/ccPxLN2a.o
ostream::operator<<(long)           /var/tmp/ccPxLN2a.o
ostream::operator<<(char const *)   /var/tmp/ccPxLN2a.o
ld: fatal: Symbol referencing errors. No output written to a.out
collect2: ld returned 1 exit status

gcc 编译器不能编译 C++ 程序吗?在相关说明中，gcc 和 g++ 之间有什么区别.谢谢，

推荐答案

gcc 实际上可以很好地编译 C++ 代码.您收到的错误是链接器错误，而不是编译器错误.

gcc info.C -lstdc++
