            GDB 7.12.1 released!

Release 7.12.1 of GDB, the GNU Debugger, is now available via anonymous
FTP.  GDB is a source-level debugger for Ada, C, C++, Objective-C,
Pascal and many other languages.  GDB can target (i.e., debug programs
running on) more than a dozen different processor architectures, and GDB
itself can run on most popular GNU/Linux, Unix and Microsoft Windows

You can download GDB from the GNU FTP server in the directory:

There is a web page for GDB at:


That page includes information about GDB mailing lists (an announcement
mailing list, developers discussion lists, etc.), details on how to
access GDB's source repository, locations for development snapshots,
preformatted documentation, and links to related information around
the net.  We will put errata notes and host-specific tips for this release
on-line as any problems come up.  All mailing lists archives are also
browsable via the web.

This version of GDB now builds with a C++ compiler by default.
It is still possible to build GDB with a C compiler by simply
configuring it with --disable-build-with-cxx.  However, future
release will require a C++ compiler to build GDB.
