You are linking it with the curses library, aren't you? (I.e, put
-lcurses on your link line. If that doesn't work, try -lncurses.)
FWIW, on one of my Red Hat 7.2 systems, I see:
$ objdump -T /usr/lib/libcurses.so | grep initscr
00014ad4 g DF .text 000000c2 Base initscr
$ objdump -T /usr/lib/libcurses.so | grep newwin
00017b30 g DF .text 0000013b Base newwin
$ objdump -T /usr/lib/libcurses.so | grep endwin
00011f94 g DF .text 00000050 Base endwin
00014ea4 g DF .text 00000029 Base isendwin
So the symbols are there... (Or at least they are on my system.)
