Did a little bit of investigation and got in touch with ncurses developer. The pkg-config file in the official ncurses distribution has been broken for years (I'm the second one to report this bug since 2011). acs_map symbol declaration misled me. Then, yes, do disregard my patch. Since the fix is closed to a typo fix, it has been silently fixed by all distros out there with a shared split ncurses package, without reporting it upstream (and that's quite a fail). At least, the info is now in all mailing list archives :) regards, -- Sylvain -- To unsubscribe from this list: send the line "unsubscribe linux-kbuild" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
