11 # Detect SysV compatible curses, such as ncurses.
13 # Defines HAVE_CURSES_H or HAVE_NCURSES_H if curses is found. CURSES_LIB
14 # is also set with the required library, but is not appended to LIBS
15 # automatically. If no working curses library is found CURSES_LIB will be
16 # left blank. If CURSES_LIB is set in the environment, the supplied value
19 # There are two options: --with-ncurses forces the use of ncurses, and
20 # --with-ncursesw forces the use of ncursesw (wide character ncurses). The
21 # corresponding options --without-ncurses and --without-ncursesw force
22 # those libraries not to be used. By default, ncursesw is preferred to
23 # ncurses, which is preferred to plain curses.
25 # ax_cv_curses is set to "yes" if any curses is found (including
26 # ncurses!); ax_cv_ncurses is set to "yes" if any ncurses is found, and
27 # ax_cv_ncursesw is set to "yes" if ncursesw is found.
