| .. section: Build |
| |
| The ncurses function extended_color_content was introduced in 2017 |
| |
| (https://invisible-island.net/ncurses/NEWS.html#index-t20170401). The |
| |
| ncurses-devel package in CentOS 7 had a older version ncurses resulted in |
| compilation error. For compiling ncurses with extended color support, we |
| verify the version of the ncurses library >= 20170401. |
