Error "undefined reference to 'std::cout'"

Shall this be the example:

#include 
using namespace std;

int main()
{
    cout << "Hola, moondo.\n";
}

It throws the error:
gcc -c main.cpp gcc -o edit main.o main.o: In function main':
main.cpp:(.text+0xa): undefined reference to std::cout'
main.cpp:(.text+0xf): undefined reference to std::basic_ostream >& std::operator>(std::basic_ostream >&, char const*)'
main.o: In function __static_initialization_and_destruction_0(int,int)':
main.cpp:(.text+0x3d): undefined reference to std::ios_base::Init::Init()'
main.cpp:(.text+0x4c): undefined reference to std::ios_base::Init::~Init()' collect2: error: ld
returned 1 exit status make: *** [qs] Error 1


Also, this example:

#include 

int main()
{
    std::cout << "Hola, moondo.\n";
}

throws the error:
gcc -c main.cpp gcc -o edit main.o main.o: In function main':
main.cpp:(.text+0xa): undefined reference to std::cout'
main.cpp:(.text+0xf): undefined reference to std::basic_ostream >& std::operator>(std::basic_ostream >&, char const*)'
main.o: In function __static_initialization_and_destruction_0(int,int)': main.cpp:(.text+0x3d): undefined reference to std::ios_base::Init::Init()'
main.cpp:(.text+0x4c): undefined reference to std::ios_base::Init::~Init()' collect2: error: ld
returned 1 exit status make: *** [qs] Error 1


Note: I am using Debian 7 (Wheezy).

Compile the program with:
g++ -Wall -Wextra -Werror -c main.cpp -o main.o
^^^^^^^^^^^^^^^^^^^^

as cout is present in the C++ standard library, which would need explicit linking with -lstdc++ when using gcc; g++ links the standard library by default.

With gcc, (g++ should be preferred over gcc)
gcc main.cpp -lstdc++ -o main.o
