On my gentoo system (x86_64) with ncurses 5.9, after applying this patch, -lncurses is linked, but not -lncursesw. > > Good question, I actually do not know, and I don't have an ncurses > pkgconfig around to see if that works. > > Alexandra, can you see if this works with: > > +PKG_CHECK_MODULES([NCURSES], [ncursesw ncurses], [LIBS="$LIBS $ncurses_LIBS"], After hacking in this change, both -lncursesw and -lncurses are linked.
