URGENT!!! - How to run GitHub code onto vs in ubuntu ute

This works without any homebrew installed ncurses… and using clang++ or its g++ proxy… on Sequoia v15.4.1 and latest Xcode 16.3 and/or its accompanying Command Line Tools clang v17.0.

// clang++ -O2 -o curse_this curse_this.cpp -lncurses --std=c++23
// g++ -O2 -o curse_this curse_this.cpp -lncurses --std=gnu++23

#include <cstdlib>
#include <ncurses.h>

using namespace std;

int main(int argc, char **argv)
{
    // init screen and sets up screen
    initscr();

    // print to screen
    printw("Hello World");

    // refreshes the screen
    refresh();

    // pause the screen output
    getch();

    // deallocates memory and ends ncurses
    endwin();
    return 0;
}

Actually, a correction to my previous post - at least vis-a-vis macOS (and I still don't know if you are actually using - or supposed to be using - macOS or Linux for this).

ncursesw actually appears to be generated when ncurses is compiled with wide-character support. Whether you invoke ncurses in code with

#include <curses.h>

or

#include <ncurses/curses.h>

depends on whether ncurses is the default curses on your system or not (in which case it would have been compiled to not overwrite curses and thus put headers in ncurses/curses.h). But note the header name is curses.h, not ncurses.h - again, based on the macOS man pages...Linux might be different.

Depending on whether you have standard or wide character support will also affect if you are linking to -lncurses or -lncursesw.

So, it would appear to me that you ought to be including

#include <ncurses/curses.h>

and maybe linking with -lncursesw at some point, although who knows what development environment you are actually using...

Is this assignment making assumptions about your development environment - specifically is it assuming that you are using a Linux environment (or does the course specify a Linux environment)?

ncursesw is the ncurses development environment - are you certain you have it installed? is it installed in the location the program you are trying to build expects? A fatal error involving

#include <ncursesw/ncurses.h>

seems like a namespace error to me. So again, is everything set up in accordance with what this assignment requires, or are you installing things based on random Internet posts on random forums?

The ncurses library is built into the operating system. There is nothing else you need to install.

Concur.

It also works using curses.h in the include and without specifying the standard (the code is so basic the C++ standard hardly matters), or any valid standard really.
