Question about g++


Hello All!

I am new to this list as well as cygwin.  I tried to compile following very 
simple program.   However, I just got a lot of error messages, which is 
bellow the program.  If I use -c switch (g++ -c helllo.cc), I get an object 
file, so I think the compiler is OK.  Could anybody tell me how to solve 
the problem?

Thanks


#include <iostream>

using namespace std;

int main(void)
{
   cout << "Hello World" << endl;

   return 0;

}
