Versions of Ncurses Libraries
  =============================

There are several Ncurses Libraries which can be used for building
with an terminal based application.  The standard Ncurses Libraries
is given with ABI 5.9

       /usr/include/ncurses/*.h
       /usr/lib/libncurses.so  or /usr/lib64/libncurses.so
       /usr/lib/libform.so     or /usr/lib64/libform.so
       /usr/lib/libmenu.so     or /usr/lib64/libmenu.so
       /usr/lib/libpanel.so    or /usr/lib64/libpanel.so

and its header are installed in /usr/include/ncurses/ e.g.
ncurses.h.  For backward compatibility with simply older
programs the headers curses.h, ncurses.h, and term.h
will be also found in /usr/include/.  Use the output of

       ncurses5-config --cflags  for CFLAGS
       ncurses5-config --libs    for LDFLAGS

to extend the CFLAGS and the LDFLAGS.
For a version with wide character support please use the
libraries with old ABI 5.9

       /usr/include/ncursesw/*.h
       /usr/lib/libncursesw.so or /usr/lib64/libncursesw.so
       /usr/lib/libformw.so    or /usr/lib64/libformw.so
       /usr/lib/libmenuw.so    or /usr/lib64/libmenuw.so
       /usr/lib/libpanelw.so   or /usr/lib64/libpanelw.so

Use the output of

       ncursesw5-config --cflags for CFLAGS
       ncursesw5-config --libs   for LDFLAGS

to extend the CFLAGS and the LDFLAGS.
For a thread safe version (also known as `reentrant') please
use the libraries with ABI 6.0

       /usr/include/ncurses6/ncurses/*.h
       /usr/lib/ncurses6/libncurses.so  or /usr/lib64/ncurses6/libncurses.so
       /usr/lib/ncurses6/libform.so     or /usr/lib64/ncurses6/libform.so
       /usr/lib/ncurses6/libmenu.so     or /usr/lib64/ncurses6/libmenu.so
       /usr/lib/ncurses6/libpanel.so    or /usr/lib64/ncurses6/libpanel.so

together with the header files found at /usr/include/ncurses6/ncurses/
e.g. ncurses.h. For backward compatibility with simply older programs
the headers curses.h, ncurses.h, and term.h will be also found in
/usr/include/ncurses6/.  Use the output of

       ncurses6-config --cflags  for CFLAGS
       ncurses6-config --libs    for LDFLAGS

to extend the CFLAGS and the LDFLAGS.
For a version with both wide character support and thread safe
please use the libraries with ABI 6.0

       /usr/include/ncurses6/ncursesw/*.h
       /usr/lib/ncurses6/libncursesw.so or /usr/lib64/ncurses6/libncursesw.so
       /usr/lib/ncurses6/libformw.so    or /usr/lib64/ncurses6/libformw.so
       /usr/lib/ncurses6/libmenuw.so    or /usr/lib64/ncurses6/libmenuw.so
       /usr/lib/ncurses6/libpanelw.so   or /usr/lib64/ncurses6/libpanelw.so

Use the output of

       ncursesw6-config --cflags for CFLAGS
       ncursesw6-config --libs   for LDFLAGS

to extend the CFLAGS and the LDFLAGS. It should be noted that the ABI 6.0
is not only thread safe but also includes extended mouse support and in
case of the wide character version also extended color support.
