Sorry, don't understand your message. The ncursesw header is invoked
by the -lncursesw compile line option above, *and* by #include
<ncursesw/curses.h> in the file itself; isn't that enough?!

> pkg-config --cflags ncursesw

Can't use pkg-config on this project; it must be compilable on
machines that don't have it installed.

Okay...  The synopsis of gcc in the man page says the file to be
compiled should come last in the compile line.  That's the only thing
I can see here that could be called an "object".  The only thing that
could be called a "library" is specified by an -l option.  Rearranging
according to the order of things given in the synopsis, I get:

gcc -c -Wall -Werror -D_XOPEN_SOURCE_EXTENDED -lncursesw  -o display.o \
display.c

Is that what you meant?  And in that case are you calling -Wall and
- -Werror "objects"?  and -D_XOPEN_SOURCE_EXTENDED a "library"?
If so why?
