things so that it uses the same malloc as is used by the program being executed. This has several advantages, the big one being that you can now debug core dumps from dynamically linked programs and get useful information out of them. Until now, that didn't work. The internal malloc package placed the tables describing the loaded shared libraries in a mapped region of high memory that was not written to core files. Thus the debugger had no way of determining what was loaded where in memory. Now that the dynamic linker uses the application's malloc package (normally, but not necessarily, the system malloc), its tables end up in the regular heap area where they will be included in core dumps. The debugger now works very well indeed, thank you very much. Also ... Bring the program a little closer to conformance with style(9). There is still a long way to go. Add minimal const correctness changes to get rid of compiler warnings caused by the recent const changes in <dlfcn.h> and <link.h>. Improve performance by eliminating redundant calculations of symbols' hash values.
This is the top level of the FreeBSD source directory. This file was last revised on: $Id: README,v 1.10 1997/02/23 09:18:39 peter Exp $ For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information). The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree, the most commonly used one being ``world'', which rebuilds and installs everything in the FreeBSD system from the source tree except the kernel and the contents of /etc. Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags. Building a kernel with config(8) is a somewhat more involved process, documentation for which can be found at: http://www.freebsd.org/handbook/kernelconfig.html And in the config(8) man page. The sample kernel configuration files reside in the sys/i386/conf sub-directory (assuming that you've installed the kernel sources), the file named GENERIC being the one used to build your initial installation kernel. The file LINT contains entries for all possible devices, not just those commonly used, and is meant more as a general reference than an actual kernel configuration file (a kernel built from it wouldn't even run).
