Problem with curses.h library on M1 arm64 processor

Question

I am a macOS user with an M1 processor. For my project (without going into details) I decided to use the library: curses.h The problem is that I get an error message about "Undefined symbols for architecture arm64". I would like to ask for help in solving the problem if possible. Im using CLion. C++ standard 20, MacOS 13.2.1. Here is my code:

#include <curses.h> 
int main() {

    initscr();
    keypad( stdscr, TRUE );
    printw( "Character in bold:\n\n" );
    noecho(); // 2
    int letter = getch();
    printw( "The pressed char is:" );
    attron( A_BOLD );
    printw( "%d", letter );
    getch();
    endwin();

}

And my error:

FAILED: NameOfProject

I've tried to go online and reinstall ncurses, but it hasn't fixed anything. Using -lcurses doesn't work.

`curses.h` is not the "library". Its the header you include. You miss to link the library — 463035818_is_not_an_ai, May 23 '23 at 09:16
"Using -lcurses doesn't work." why not? What happens when you try to link it? — 463035818_is_not_an_ai, May 23 '23 at 09:16
My guess would be you've got an intel build of curses, you need to rebuild it for arm — Alan Birtles, May 23 '23 at 09:17
Goodness me, someone still using `curses`. Last time I encountered this was about 1987. — user207421, May 23 '23 at 10:17
