Yes; these error messages are not from the compile, but from the link 
phase, and probably mean that you have not linked in the library 
containing the actual code for the functions referenced. So to link code 
for ncurses, you will probably have to specify -lncurses somewhere on 
your gcc invocation (this is documented in `man ncurses').
