help installing ncurses (mac)

[heyyouyesyouiloveyou]

I am trying this simple ncurses program, and I get an error I cannot interpret.

#include <ncurses.h>
#include <iostream>
using namespace std;

int main() {
	initscr();
	printw("Hello, world!");
	refresh();
	getch();
	endwin();
	return 0;
}

/bin/sh -c '/usr/bin/make -j4 -e -f  Makefile'
----------Building project:[ Beads - Debug ]----------
/usr/bin/g++   -c  "/Users/Nihar/C++/beadsGame/main.cpp" -g -O0 -Wall  -o ./Debug/main.cpp.o -I. -I.
/usr/bin/g++  -o ./Debug/Beads @"Beads.txt" -L.

Help is appreciated, thanks!

You forgot to link with libcurses.

Will you please explain what that is and where to find it?

[Duthomhas]

All the code that does stuff is in a "library" somewhere -- code that has already been compiled and ready to link to your program -- either as part of your final executable/binary or as a dynamic link file (".so" on OSX).

Functions and stuff that comes with C++ (things like cout, printf(), etc) is automatically linked for you. Stuff that does not come with it (like NCurses functions: wprintf(), etc) is not. You need to tell the compiler/linker where to find the library file so that it can be linked to the code you wrote.

Hope this helps.
