One would expect, that --with-ncurses means: Use ncurses(w), and if it
is not available, force to fail. But ./configure --help tells something
different:
--with-ncurses build with non-wide ncurses, default is wide version
(--without-ncurses disables all ncurses(w) support)
It implies, that --without-ncurses should force-disable non-wide ncurses.
In fact, none of that is true. The check now works in a strange way:
--without-ncurses means:
Disable any variant of ncurses.
--with-ncurses means:
- If ncurses is detected by pkgconfig files, --with-ncurses is a NOP.
- If pkgconfig files are not present, it falls back to the described
meaning: Force non-wide variant of the library.
Additionally, --with-ncurses does not disable widechar support, which
has unexpected results (see my mail [PATCH] Don't allow widechar with
plain ncurses)
What would be the better fix?
- Change description of --with-ncurses, and change behavior of library
check. If ncursesw is not found, disable widechar support. Optionally
add --disable-widechar to replace original meaning of --with-ncurses.
- Keep description as it is, and fix the main AS_IF and pkgconfig check
to follow the description. --with-ncurses will disable widechar
support. Optionally add --with-ncursesw.
