I have been building the C++ Translator, Release 1.0 and have
a question.

I followed the tips from Jonathan P. Leech in his posting to
this newsgroup <278@cit-vax.Caltech.Edu>, dated 24 March 1986.
I was able to build a cfront successfully and even tested munch
with the "Hello, world" program.  But I have tried an example
program from the Release Notes and am unsuccessful in getting it
to compile.  The program is:


	#include <complex.h>
	
	main(){
		complex xx;
		complex yy = complex(1,2.718);
		xx = log (yy/3);
		cout << 1+xx;
	}

When I compile it with CC, I get the following errors:

	CC  test.c:
	cc   test..c -lC
	Undefined:
	_log
	_atan2

Any help will be greatly appreciated.  I am building the translator
on a VAX 11/780 running 4.2BSD.

Try saying

	CC test.c -lm
