Cannot find ncurses.h header file

Introduction#

GNU ncurses is a software API for controlling the writing to the console screen on Unix, Linux, and other operating systems. The ncurses library can be used to create text-based user interfaces (TUI) on Linux or Unix-like systems.

ncurses (new curses) is a programming library that provides a series of functions to facilitate the generation of text-based user interfaces.

In fact, we are not unfamiliar with ncurses itself, as the following well-known software all use ncurses:

vim
emacs
lynx
screen
......

Installation and Usage#

Using Ubuntu 22.04 as an example

sudo apt-get install libncurses5-dev

After installation, we can use the following code to test if the installation was successful

#include <string.h>
#include <ncurses.h>


int main(int argc, char* argv[]) {

    initscr();
    raw();
    noecho();
    curs_set(0);

    char* s = "Hello, Liu Yuhe!";

    // Print the string in the center of the screen
    mvprintw(LINES / 2, (COLS - strlen(s)) / 2, "%s", s);
    refresh();

    getch();
    endwin();

    return 0;
}
