This copies in libbacktrace from the gcc repository as it was in the commit 62e420293a293608f383d9b9c7f2debd666e9fc9. GDB is going to start using this library soon. A dependency between GDB and libbacktrace has already been added to the top level Makefile, so, after this commit, when building GDB, libbacktrace will be built first. However, libbacktrace is not yet linked into GDB, or used by GDB in any way. It is possible to stop libbacktrace being built by configuring the tree with --disable-libbacktrace. This commit does NOT update src-release.sh, that will be done in the next commit, this commit ONLY imports libbacktrace from gcc. This means that if you try to make a release of GDB from exactly this commit then the release tar file will not include libbacktrace. However, as libbacktrace is an optional dependency this is fine.
README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
