Hello Dave, Thank you for your message. i found and corrected the error. i do not know which piece of software installed /usr/local/lib/libncurses++w.a => /usr/local/lib/libncursesw.a /usr/local/lib/libncurses++w_g.a -> libncursesw_g.a /usr/local/lib/libncursesw.a /usr/local/lib/libncursesw_g.a renaming them temporarily solved the problem.
