Pseudo-Incremental Linking for C/C++ 
by William A. Hoffman and Rupert W. Curwen


Example 1: 

#include "classtest.h"
extern "C" int classtest()
{
   ClassTest c;
   c.test1();
   c.test2();
   return 1;
}

Example 2:

(gdb) set auto-so-lib 0
(gdb) b main
Breakpoint 1 at 0x17588: file main.cc, line 5.
(gdb) run
Starting program: /home/form/toplevel/bin/sun4-solaris/toplevel
