How to add ncurses library to project?

maydin

I am trying to start with ncurses library but QtCreator does not compile it. Here is the simple code:

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

using namespace std;

int main(int argc, char *argv[])
{
    initscr();			/* Start curses mode 		  */
    printw("Hello World !!!");	/* Print Hello World		  */
    refresh();			/* Print it on to the real screen */
    getch();			/* Wait for user input */
    endwin();			/* End curses mode		  */

    return 0;
}

I added to .pro file these lines but i could not find where i am doing wrong:

QMAKE_CXXFLAGS += -lncurses
QMAKE_CXXFLAGS_DEBUG += -lncurses

When I compile it with g++ manually with -lncurses option it works though. QtCreator gives me undefined reference for those functions.

Hi! Your *.pro file should contain:

INCLUDEPATH += /path/to/ncurses/headers/
LIBS += -L/path/to/ncurses/library/ -lncurses

@Wieland I have just added this and it works:

LIBS += -L/usr/include -lncurses

But I dealed with finding include path still, I don't know why only -lncurses is not enough.

Hi you also need to tell about
.h files with
INCLUDEPATH += /path/to/ncurses/headers/
as @wieland says

@maydin As libs are not located in include directories it should be:

LIBS += -L/usr/lib -lncurses
