problem using curses.h

[vehshiCoder]

hi,
i got NCurses.h (which includes curses.h, term.h and many others) through command
$ sudo apt-get install libncurses5-dev libncursesw5-dev
it downloaded and is appearing in netbeans 6.9 ide's intellisense when including it. But the ide is putting a red line under it saying no such library exists although it predicts it. And when functions of this library are called, ide says undefined reference to XYZfunction.
for example i tried using it in this way

int main()
  {
  char users_name[ 100 ];

  initscr();
  (void)echo();

  addstr( "What is your name> " );
  refresh();
  getnstr( users_name, sizeof( users_name ) - 1 );

  clear();

  printw( "Greetings and salutations %s!\n", users_name );
  refresh();

  printw( "\n\n\nPress ENTER to quit." );
  refresh();
  getnstr( users_name, sizeof( users_name ) - 1 );

  endwin();
  return 0;
}

and errors are

#include <curses.h>
A program using these routines must be linked with the -lncurses option, or (if it has been generated) with the debugging library -lncurses_g.

Check your IDE documentation.

i am newbie..... can you explain me further?

I don't really know about IDE's so bare with me. First you should try to compile your work in console as follows:
g++ <all necessary c++ files> -lncurses
if that works you should check that your IDE passes argument "-lncurses" during compilation.

EDIT:
g++ -o dist/Debug/GNU-Linux-x86/net_test build/Debug/GNU-Linux-x86/main.o
that is compilation and there is no "-lncurses" ;)
