Print a wide unicode character with ncurses
c, ncurses, unicode
Solution
You must be compiling against the "narrow" curses (ncurses vs ncursesw)
I was able to compile your example on ubuntu 16.04 with the following:
apt install libncursesw5-dev
# --cflags expanded to: -D_GNU_SOURCE -I/usr/include/ncursesw
gcc main.c $(ncursesw5-config --cflags) -c
# --libs expanded to: -lncursesw -ltinfo
gcc main.o $(ncursesw5-config --libs) -o main
And then
./main
I had to make the following diff to your example code as well:
- const wchar_t* star = L"0x2605";
+ const wchar_t* star = L"\x2605";
Problem
I'm trying to position a star unicode character on screen using the `ncurses.h` library in C on Ubuntu. The code I'm trying to run is the following: ``` #include <stdio.h> #include <wchar.h> #include <curses.h> #include <ncurses.h> #include <stdlib.h> #include <wctype.h> #include <locale.h> int main() { setlocale(LC_CTYPE, ""); initscr(); cbreak(); WINDOW *win = newwin(0, 0, 0, 0); refresh(); wrefresh(win); const wchar_t* star = L"0x2605"; mvaddwstr(3, 3, star); getch(); endwin(); } ``` But I keep getting the error ``` implicit declaration of function ‘mvaddwstr’ [-Wimplicit-function-declaration] ``` Despite this function being well documented here together with similar functions which I can't get to work either. Is there some library I'm not including to make this work? or is there an alternative way to go about displaying this character? I appreciate any help.
