macOS gcc, c++ compiling problems

[davidlt]

naujas.cpp:

#include <iostream>

int main()
{
   std::cout << "Hello World!";
   return 0;
}

of course you can use "using namespace std;" and you don't need to write like this std::cout.

Compiling:

gcc -o naujas naujas.cpp

Problems:

macbook:~/sandbox marius$ gcc -o naujas naujas.cpp
/usr/bin/ld: Undefined symbols:
std::ios_base::Init::Init()
std::ios_base::Init::~Init()
std::cout
std::basic_ostream<char, std::char_traits<char> >& std::operator<< <std::char_traits<char> >(std::basic_ostream<char, std::char_traits<char> >&, char const*)
___gxx_personality_v0
collect2: ld returned 1 exit status

For my eyes it looks like the problem is with std library, but I don't know much about C++. Any ideas how I could compile it? I would like to find out, I will be programming in C/C++ in University using Debian/Solartis.

By the way, I can compile C code with gcc using Mac.

Try using g++ instead of gcc

Worked just perfect, thanks for this one. But why gcc can't compile C++ code?

because g c c = gnu C compiler
