How I can link standard C++ libraries with g++ on Windows? - c++

Question

I just have a simple structure:
main.cpp
#include <iostream>
#include "../header_files/h.h"
int main(void)
{
f();
g();
}
src1.cpp
#include <iostream>
void f() { std::cout << "f()" << std::endl; };
void g() { std::cout << "g()" << std::endl; };
h.h
void f(); void g();
I am trying to (only) compile main.cpp and src1.cpp with:
PS> g++ -c main.cpp src.cpp
Then get an executable from the created .obj files:
PS> g++ main.o src.o -o exec.exe
.\ss.o:ss.cpp:(.text+0x17): 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*)
\ss.o:ss.cpp:(.text+0x26): undefined reference to std::ostream::operator<<(std::ostream& (*)(std::ostream&))
\ss.o:ss.cpp:(.text+0x41): undefined reference to std::ios_base::Init::~Init()
\ss.o:ss.cpp:(.text+0x71): undefined reference to std::ios_base::Init::Init()
Here I am getting a verbose linker error; that's because I am using iostream library; I just need to tell g++ how to link to this library or any other standard library I want to use. How I can do that?
Actually I can use g++ main.cpp src1.cpp -o test, or using any IDE, but I do not need to do this. Just need a way to tell g++ (maybe via command-line args) how to go to the actual definitions. I need to produce the .exe file from the generated obj files, not something else.
