So probably our new error does not really > make sense: "wide-char support enabled, but non-wide ncurses selects" Well, the idea is to keep it simple, "may have wide char" sounds like we need compile test to be sure. That's crazy. Maybe assume that "w" mean wide is good enough. > I wonder why we don't try the config scripts (--libs --cflags) in this > order: > ncursesw6-config > ncurses6-config > ncursesw5-config > ncurses5-config Parallel universe :-) > Looks like they are always installed by default and also always with the > right suffixes. No fallback needed if we don't use pkg-config at all. I'll try to fix it and use pkg-config and if not available then ncurses-config. Yes, I think that prefer de-facto standard pkg-config with generic PKG_* autoconf macros is a good idea.
