[comp.lang.c++] C++ Curses and g++

king1@husc10.harvard.edu (Gary King) (05/04/91)

I'm writing a c++ program that does screen manipulation and 
am unable to tie curses in with it.  I compile using:
	g++ -o name prog.c -lcurses -ltermlib
and the linker complains about _unctrl being undefined.  _unctrl
is declared in /usr/include/curses.h (used to be in /usr/include/unctrl.h)
as an external variable but I would think that it would be defined
somewhere.  

I also wrote a little program with a declared (but *undefined*) 
external variable and both cc and g++ didn't mind that at all:

	#include	<stdio.h>
	
	/*
	 * Used to be in unctrl.h.
	 */
	#define	unctrl(c)	_unctrl[(c) & 0177]
	extern char *_unctrl[];
	extern char	_c[];
	
	main() {
		printf( "Now is the time\n" );
	}

It compiles, links and runs just fine....

So, does anyone out here in C++-guru-land have any suggestions.  If
I get a lot of responses and they are non-trivial, I'll post a 
summary.  Sorry if this is an FAQ... but help!
