The pkg-config files were introduced in ncurses 5.9 (2011). But they are still not enabled by default. So many distros may still miss it and users who install ncurses from source will probably also miss it in the first run. That's a bit annoying. Actually I was not even able to figure out quickly how to install ncursesw.pc. Looks like this would be needed ./configure --enable-pc-files --enable-widec --enable-lib-suffixes --enable-pc-suffixes That also means that ncurses without suffix "w" may have wide char support if not configured with --enable-lib-suffixes and --enable-pc-suffixes. So probably our new error does not really make sense: "wide-char support enabled, but non-wide ncurses selects" I wonder why we don't try the config scripts (--libs --cflags) in this order: ncursesw6-config ncurses6-config ncursesw5-config ncurses5-config 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. cu, Rudi -- To unsubscribe from this list: send the line "unsubscribe util-linux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
