Compile ncurses program

Installing the toolchain, plus including the ncurses directory during compilation, plus statically linking some libraries the executable couldn't find seems to have done the trick. Add a comment. Active Oldest Votes. Improve this answer. Sign up or log in Sign up using Google.

Getting Started with ncurses. How to use curses to draw to the terminal screen. Sierpinski's Triangle One simple way to demonstrate a few curses functions is by generating Sierpinski's Triangle.

If you aren't familiar with this method to generate Sierpinski's Triangle, here are the rules: Set three points that define a triangle. Randomly select a point anywhere x,y. Then: Randomly select one of the triangle's points. Set the new x,y to be the midpoint between the previous x,y and the triangle point. The noecho function tells curses not to echo the input back to the screen, and the clear function clears the screen: 20 initscr ; 21 cbreak ; 22 noecho ; 23 24 clear ; The program then sets a few variables to define the three points that define a triangle.

First, the program draws the three points that define the triangle, labeled "0", "1" and "2": 40 mvaddch y[0], x[0], '0' ; 41 mvaddch y[1], x[1], '1' ; 42 mvaddch y[2], x[2], '2' ; To draw the random starting point, the program makes a similar call: 49 mvaddch yi, xi, '. Then I call endwin to exit the curses environment and return the terminal screen to normal control: 69 getch ; 70 endwin ; Compiling and Sample Output Now that you have your first sample curses program, it's time to compile and run it.

Figure 1. Output of the triangle Program Despite the random nature of the iteration, every run of Sierpinski's Triangle will look pretty much the same. Starting to Learn ncurses This program is a simple example of how to use the curses functions to draw characters to the screen. Recent Articles. Charles Fisher. Active Oldest Votes. Improve this answer. Karoly Horvath Karoly Horvath Do I always have to do this whenever I'm using a library not included in the compiler?

The header file allows your code to compile by matching a function declaration to calls in your code. The linker's job is to find the actual runnable code for every function used in your program, and that's by specifying the encapsulating library name at link-time as well as the object files for your own code. Exactly - you need to link to all libraries, even the standard ones. The only reason you haven't realized this so far is that GCC automatically links libc unless you tell it not to do so with -ffreestanding — Karoly Horvath.
