Question

I know this topic was few times there, but I can’t get satisfactory answer.

C:\Users\Krzysiek>gcc test.c
test.c:3:20: fatal error: iostream: No such file or directory
compilation terminated.

This is what I try to do

#include <iostream>
using namespace std;

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

Simple program with “include”

I’ve heard of LIBRARY_PATH. So I’ve setted that. Still this same error I have.

GCC provides wrappers around calling its various compilers.

• You are using gcc, which is for C (and consequently will not include or link the C++ standard library; the compiler would go on to complain about the rest of your code, too, since it’s not valid C);

• Use g++, which is for C++.

Also try to use a conventional extension for C++ source files, which is .cc, .cxx or .cpp.
