Date: Thu, 6 Jun 2013 18:51:37 +0000 From: Ed Maste <emaste@freebsd.org> To: freebsd-hackers@freebsd.org Subject: [PATCH] Install standalone debug files in /usr/lib/debug Message-ID: <20130606185137.GA1806@sandvine.com>
next in thread | raw e-mail | index | archive | help
Add a new knob WITH_DEBUG_FILES to control the building of standalone
debug files for userland programs and libraries. The "-g" debug flag
is automatically applied when WITH_DEBUG_FILES is set.
The debug files are now named ${prog}.debug and ${shlib}.debug for
consistency with other systems and documentation. In addition they are
installed under /usr/lib/debug, to simplify the process of installing
them if needed after a crash. Users of bsd.{prog,lib}.mk outside of the
base system place the standalone debug files in a .debug subdirectory.
GDB automatically searches both of these directories for standalone
debug files.
Thanks to everyone who contributed changes, review, and testing during
development.
---
Changes since previous version of the patch:
. some cleanup suggested by brooks@ and kib@
. separate debug tree into separate mtree file
. use new DEBUGMODE variable rather than BINMODE / LIBMODE, to avoid
suid or sgid debug files
