Problems setting up Ncurses and C++

I'm fairly new to C++ and I'm trying to set up ncurses, but I can't get it to work. Here's the code:

#include <iostream>
#include <string>
#include <ncurses.h>
      int main(){
        initscr();
        printw("Hello World !!!");
        refresh();
        getch();
        endwin();
        return 0;
    }

With this file I get 'undefined reference' errors

And here is the makefile:

main.o: main.cpp ncurses.h
    g++ main.cpp -o crawler -lncurses

The error I get with the makefile is :

make: *** No rule to make target `ncurses.h', needed by `main.o'.  Stop.

Thanks for your help!

Note: I am using Ubuntu 12.04 with Geany and g++

You should remove ncurses.h dependency from Makefile. You Makefile should look like this:

main.o: main.cpp
    g++ main.cpp -o crawler -lncurses

make tries to find ncurses.h in current working directory, but it is not available there. So make indicates error.

Also, there is no need of iostream and string headers in your code, because string header is included by iostream and you are not using any functions from both of headers.
