BUILD FAILED (exit value 2, total time: 477ms)

It appears it cannot find ”lcurses” but I never defined for it to look for lcurses. I actually added ncurse libraries to be linked.

I have navigated to /usr/include/ncurses and there is in fact the files there should be.

I don’t fully know what is going on through this whole compiling stuff it is a little beyond me. I just know that I was told to link the libraries I need. ncurses.h is there this is how I have my code.

#include <iostream>
#include <ncurses/ncurses.h>

using namespace std;


bool kbhit()
{
  int ch = getch();
  if(ch != ERR)
  {
    ungetch(ch);
    return true;
  }
  return false;

}

int main() {

  while(!kbhit())
  {
    cout << "no input";
  }
  cout << "Mummy, it's over.";
  return 0;
}

Any help would be pleasantly welcome; I am lost.

    this is not a problem with your c++ code, it’s more a problem with your build enviroment, are you using netbeans IDE?

    This code as far as I can tell does not require ncruses at all, and the link directive that NetBeans? has set up for you points to a ncruses.h file where it should be something like this “-Wl,-lncurses” or only “-lncurses”. So a guess is that somewhere in netbeans where you should point out the library name you have written ncruses.h instead of only ncruses(i think, not sure)

    try to ask pkg-config what parameters for ncurses should be on your machine “pkg-config –libs ncurses” and “pkg-config –cflags ncurses”
