The second example (using <code>&lt;curses.h&gt;</code>) will work with MacOS if you use a command like this:

<pre><code>gcc -o foo -D_XOPEN_SOURCE_EXTENDED foo.c -lncurses
</code></pre>

That is:

<ul>
<li>you have to turn on a definition to make the wide-character features visible (which you could see by reading the header file), and</li>
<li>the library name is "ncurses" (although it contains the wide-character functions).</li>
</ul>

Do

<pre><code>nm /usr/lib/libncurses.dylib | grep addwstr
</code></pre>

to see this:

<pre><code>0000000000024c39 T _addwstr
0000000000024fba T _mvaddwstr
00000000000254ad T _mvwaddwstr
000000000002580c T _waddwstr
</code></pre>

As of mid-2018, MacOS bundles only a very old ncurses library (5.7, released in <a href="https://invisible-island.net/ncurses/ncurses.faq.html#other_versions" rel="nofollow noreferrer">2008</a>), and a correspondingly old terminal database. You can see that by

<pre><code>$ /usr/bin/tic -V
ncurses 5.7.20081102
</code></pre>

Interestingly, the dynamic library's filename hints that it is really ncurses 5.4 (another 4 years older), but the compiled-in version shown by <code>tic</code> and the <code>curses.h</code> header file tell the actual version. As noted, that library contains the symbols which would be needed by the wide-character library. The name-distinction between ncurses and ncursesw libraries used for most systems predates ncurses 5.4 (again) by a few years, so Apple's configuration would be confusing to most developers.

For development you should consider using something more recent, e.g., <a href="https://www.macports.org/ports.php?by=library&amp;substr=ncurses" rel="nofollow noreferrer">MacPorts</a> or <a href="https://formulae.brew.sh/formula/ncurses" rel="nofollow noreferrer">homebrew</a>. For those, the configuration details are readily available and (unsurprisingly) provide ncursesw libraries.

OS X 10.13.2 (high sierra).

I'm trying to write simple curses program with widechar support, but it appears, that default (pre-installed library) curses doesn't support widechar:

Simplest program example (from <a href="https://stackoverflow.com/a/15245808/7936526">here</a>):

<pre><code>#include &lt;ncursesw/ncurses.h&gt;
#include &lt;locale.h&gt;
#include &lt;wchar.h&gt;

int main() {
 setlocale(LC_ALL, "");
 initscr();
 wchar_t wstr[] = { 9474, L'\0' };
 mvaddwstr(0, 0, wstr);
 refresh();
 getch();
 endwin();
 return 0;
}
</code></pre>

doesn't compile, gives error:

<blockquote>
 test.cpp:1:10: fatal error: 'ncursesw/ncurses.h' file not found
</blockquote>

Tried to find in manual pages:

<blockquote>
 man addwstr 
 says:
</blockquote>

<pre><code> #include &lt;curses.h&gt;

 int addwstr(const wchar_t *wstr);
 int addnwstr(const wchar_t *wstr, int n);
 int waddwstr(WINDOW *win, const wchar_t *wstr);
 int waddnwstr(WINDOW *win, const wchar_t *wstr, int n);
 int mvaddwstr(int y, int x, const wchar_t *wstr);
 int mvaddnwstr(int y, int x, const wchar_t *wstr, int n);
 int mvwaddwstr(WINDOW *win, int y, int x, const wchar_t *wstr);
 int mvwaddnwstr(WINDOW *win, int y, int x, const wchar_t *wstr, int n);
</code></pre>

As man page says, tried to include "curses.h" instead of "ncursesw/ncurses.h". Again compile error:

<blockquote>
 test.cpp:9:5: error: use of undeclared identifier 'mvaddwstr'; did you mean 'mvaddstr'?
</blockquote>

Tried to find any widechar-related curses header in /usr/include. No result. Any suggestions?
