Unpacking and Installation -- quick overview
==========================
- In this release, the GDB debugger sources, the generic GNU include
+ The release is provided as a gzipped tar file called
+'gdb-VERSION.tar.gz', where VERSION is the version of GDB.
+
+ The GDB debugger sources, the generic GNU include
files, the BFD ("binary file description") library, the readline
library, and other libraries all have directories of their own
-underneath the gdb-5.0 directory. The idea is that a variety of GNU
+underneath the gdb-VERSION directory. The idea is that a variety of GNU
tools can share a common copy of these things. Be aware of variation

-a release other than the gdb release (such as a binutils or gas
-release), especially if the releases are more than a few weeks apart.

Configuration scripts and makefiles exist to cruise up and down this
directory tree and automatically build all the pieces in the right
order.
- When you unpack the gdb-5.0.tar.gz file, you'll find a directory
-called `gdb-5.0', which contains:
+ When you unpack the gdb-VERSION.tar.gz file, it will create a
+source directory called `gdb-VERSION'.
+
+You can build GDB right in the source directory:
+
+ cd gdb-VERSION
+ ./configure
+ make
+ cp gdb/gdb /usr/local/bin/gdb (or wherever you want)
- COPYING config.if install-sh mmalloc readline
- COPYING.LIB config.sub intl move-if-change sim
- Makefile.in configure libiberty mpw-README symlink-tree
- README configure.in ltconfig mpw-build.in texinfo
- bfd djunpack.bat ltmain.sh mpw-config.in utils
- config etc md5.sum mpw-configure ylwrap
- config-ml.in gdb missing mpw-install
- config.guess include mkinstalldirs opcodes
+However, we recommend that an empty directory be used instead.
+This way you do not clutter your source tree with binary files
+and will be able to create different builds with different
+configuration options.
-To build GDB, you can just do:
+You can build GDB in any empty build directory:
- cd gdb-5.0
- ./configure
- make
- cp gdb/gdb /usr/local/bin/gdb (or wherever you want)
+ mkdir build
+ cd build
+ <full path to your sources>/gdb-VERSION/configure
+ make
+ cp gdb/gdb /usr/local/bin/gdb (or wherever you want)
(Building GDB with DJGPP tools for MS-DOS/MS-Windows is slightly
-different; see the file gdb-5.0/gdb/config/djgpp/README for details.)
+different; see the file gdb-VERSION/gdb/config/djgpp/README for details.)
This will configure and build all the libraries as well as GDB. If
`configure' can't determine your system type, specify one as its
argument, e.g., `./configure sun4' or `./configure decstation'.
- If you get compiler errors during this stage, see the `Reporting
+ Make sure that your 'configure' line ends in 'gdb-VERSION/configure':
+
+ /berman/migchain/source/gdb-VERSION/configure # RIGHT
+ /berman/migchain/source/gdb-VERSION/gdb/configure # WRONG
+
+ The GDB package contains several subdirectories, such as 'gdb',
+'bfd', and 'readline'. If your 'configure' line ends in
+'gdb-VERSION/gdb/configure', then you are configuring only the gdb
+subdirectory, not the whole GDB package. This leads to build errors
+such as:
+
+ make: *** No rule to make target `../bfd/bfd.h', needed by `gdb.o'. Stop.
+
+ If you get other compiler errors during this stage, see the `Reporting
Bugs' section below; there are a few known problems.
- GDB requires an ISO-C (ANSI C) compiler. If you do not have an
-ISO-C compiler for your system, you may be able to download and
-install the GNU CC compiler. It is available via anonymous FTP from
-the directory `ftp://ftp.gnu.org/pub/gnu/gcc'.
+ GDB requires an ISO C (ANSI C) compiler. If you do not have an ISO
+C compiler for your system, you may be able to download and install
+the GNU CC compiler. It is available via anonymous FTP from the
+directory `ftp://ftp.gnu.org/pub/gnu/gcc'. GDB also requires an ISO
+C standard library. The GDB remote server, GDBserver, builds with some
+non-ISO standard libraries - e.g. for Windows CE.
+
+ GDB uses Expat, an XML parsing library, to implement some target-specific
+features. Expat will be linked in if it is available at build time, or
+those features will be disabled. The latest version of Expat should be
+available from `http://expat.sourceforge.net'.
GDB can be used as a cross-debugger, running on a machine of one
type while debugging a program running on a machine of another type.
GDB includes an already formatted copy of the on-line Info version
of this manual in the `gdb/doc' subdirectory. The main Info file is
-`gdb-5.0/gdb/doc/gdb.info', and it refers to subordinate files
+`gdb-VERSION/gdb/doc/gdb.info', and it refers to subordinate files
matching `gdb.info*' in the same directory. If necessary, you can
print out these files, or read them with any editor; but they are
easier to read using the `info' subsystem in GNU Emacs or the
`makeinfo'.
If you have `makeinfo' installed, and are in the top level GDB
-source directory (`gdb-5.0', in the case of version 5.0), you can make

- make info

If you want to typeset and print copies of this manual, you need
TeX, a program to print its DVI output files, and `texinfo.tex', the
Texinfo definitions file. This file is included in the GDB
-distribution, in the directory `gdb-5.0/texinfo'.
+distribution, in the directory `gdb-VERSION/texinfo'.
TeX is a typesetting program; it does not print files directly, but
produces output files called DVI files. To print a typeset document,
This file tells TeX how to typeset a document written in Texinfo
format. On its own, TeX cannot read, much less typeset a Texinfo file.
`texinfo.tex' is distributed with GDB and is located in the
-`gdb-5.0/texinfo' directory.

If you have TeX and a DVI printer program installed, you can typeset

Note: the following instructions are for building GDB on Unix or
Unix-like systems. Instructions for building with DJGPP for
MS-DOS/MS-Windows are in the file gdb/config/djgpp/README.
The simplest way to configure and build GDB is to run `configure'
-from the `gdb-VERSION-NUMBER' source directory, which in this example
-is the `gdb-5.0' directory.

you may need to run `sh' on it explicitly:
- sh configure
+ sh configure
If you run `configure' from a directory that contains source
-directories for multiple libraries or programs, such as the `gdb-5.0'
-source directory for version 5.0, `configure' creates configuration
-files for every directory level underneath (unless you tell it not to,
-with the `--norecursion' option).
-
- You can run the `configure' script from any of the subordinate
-directories in the GDB distribution, if you only want to configure that
-subdirectory; but be sure to specify a path to it.

- For example, with version 5.0, type the following to configure only
-the `bfd' subdirectory:

- cd gdb-5.0/bfd
- ../configure

You can install `gdb' anywhere; it has no hardwired paths. However,
you should make sure that the shell on your path (named by the `SHELL'
argument to `--srcdir', you can leave out the `--srcdir' option; it
will be assumed.)

When `configure' builds a configuration using a remote source
The `Makefile' that `configure' generates in each source directory
also runs recursively. If you type `make' in a source directory such
-as `gdb-5.0' (or in a separate configured directory configured with
-`--srcdir=PATH/gdb-5.0'), you will build all the required libraries,

+ Treat compiler warnings as werrors. Use this only with GCC. It
+ adds the -Werror flag to the compiler, which will fail the

`--target=TARGET'
Configure GDB for cross-debugging programs running on the specified
TARGET. Without this option, GDB is configured to debug programs

- hosts.

-`HOST ...'
- Same as `--host=HOST'. If you omit this, GDB will guess; it's
- quite accurate.
+`--with-gdb-datadir=PATH'
+ Set the GDB-specific data directory. GDB will look here for
+ certain supporting files or scripts. This defaults to the `gdb'
+ subdirectory of `datadir' (which can be set using `--datadir').
+
+`--with-relocated-sources=DIR'
+ Sets up the default source path substitution rule so that
+ directory names recorded in debug information will be
+ automatically adjusted for any directory under DIR. DIR should
+ be a subdirectory of GDB's configured prefix, the one mentioned
+ in the `--prefix' or `--exec-prefix' options to configure. This
+ option is useful if GDB is supposed to be moved to a different
+ place after it is built.
+
+`--enable-64-bit-bfd'
+ Enable 64-bit support in BFD on 32-bit hosts.
+
+`--disable-gdbmi'
+ Build GDB without the GDB/MI machine interface.
+
+`--enable-tui'
+ Build GDB with the text-mode full-screen user interface (TUI).
+ Requires a curses library (ncurses and cursesX are also
+ supported).
+
+`--enable-gdbtk'
+ Build GDB with the gdbtk GUI interface. Requires TCL/Tk to be
+ installed.
+
+`--with-libunwind'
+ Use the libunwind library for unwinding function call stack. See
+ http://www.nongnu.org/libunwind/index.html fro details.
+ Supported only on some platforms.
+
+`--with-curses'
+ Use the curses library instead of the termcap library, for
+ text-mode terminal operations.
+
+`--enable-profiling' Enable profiling of GDB itself. Necessary if you
+ want to use the "maint set profile" command for profiling GDB.
+ Requires the functions `monstartup' and `_mcleanup' to be present
+ in the standard C library used to build GDB, and also requires a
+ compiler that supports the `-pg' option.
+
+`--with-system-readline'
+ Use the readline library installed on the host, rather than the
+ library supplied as part of GDB tarball.
+
+`--with-expat'
+ Build GDB with the libexpat library. (Done by default if
+ libexpat is installed and found at configure time.) This library
+ is used to read XML files supplied with GDB. If it is
+ unavailable, some features, such as remote protocol memory maps,
+ target descriptions, and shared library lists, that are based on
+ XML files, will not be available in GDB. If your host does not
+ have libexpat installed, you can get the latest version from
+ http://expat.sourceforge.net.
+
+`--with-python[=PATH]'
+ Build GDB with Python scripting support. (Done by default if
+ libpython is present and found at configure time.) Python makes
+ GDB scripting much more powerful than the restricted CLI
+ scripting language. If your host does not have Python installed,
+ you can find it on http://www.python.org/download/. The oldest
+ version of Python supported by GDB is 2.4. The optional argument
+ PATH says where to find the Python headers and libraries; the
+ configure script will look in PATH/include for headers and in
+ PATH/lib for the libraries.
+
+`--without-included-regex'
+ Don't use the regex library included with GDB (as part of the
+ libiberty library). This is the default on hosts with version 2
+ of the GNU C library.
+
+`--with-sysroot=DIR'
+ Use DIR as the default system root directory for libraries whose
+ file names begin with `/lib' or `/usr/lib'. (The value of DIR
+ can be modified at run time by using the "set sysroot" command.)
+ If DIR is under the GDB configured prefix (set with `--prefix' or
+ `--exec-prefix' options), the default system root will be
+ automatically adjusted if and when GDB is moved to a different
+ location.
+
+`--with-system-gdbinit=FILE'
+ Configure GDB to automatically load a system-wide init file.
+ FILE should be an absolute file name. If FILE is in a directory
+ under the configured prefix, and GDB is moved to another location
+ after being built, the location of the system-wide init file will
+ be adjusted accordingly.
`configure' accepts other options, for compatibility with configuring
other GNU tools recursively; but these are the only options that affect
GDB or its supporting libraries.

supported for some native configurations, including Sun 3, Sun 4, and
Linux.
+The file gdb/gdbserver/README includes further notes on GDBserver; in
+particular, it explains how to build GDBserver for cross-debugging
+(where GDBserver runs on the target machine, which is of a different
+architecture than the host machine running GDB).
There are a number of remote interfaces for talking to existing ROM
monitors and other hardware:
- remote-adapt.c AMD 29000 "Adapt"
- remote-array.c Array Tech RAID controller
- remote-bug.c Motorola BUG monitor
- remote-e7000.c Hitachi E7000 ICE
- remote-eb.c AMD 29000 "EBMON"
- remote-es.c Ericsson 1800 monitor
- remote-est.c EST emulator
- remote-hms.c Hitachi Micro Systems H8/300 monitor
remote-mips.c MIPS remote debugging protocol
- remote-mm.c AMD 29000 "minimon"

- remote-vx.c VxWorks realtime kernel
-
- Remote-vx.c and the vx-share subdirectory contain a remote
-interface for the VxWorks realtime kernel, which communicates over TCP
-using the Sun RPC library. This would be a useful starting point for
-other remote- via-ethernet back ends.
-
- Remote-udi.c and the 29k-share subdirectory contain a remote
-interface for AMD 29000 programs, which uses the AMD "Universal Debug
-Interface". This allows GDB to talk to software simulators,
-emulators, and/or bare hardware boards, via network or serial
-interfaces. Note that GDB only provides an interface that speaks UDI,
-not a complete solution. You will need something on the other end
-that also speaks UDI.

-Reporting Bugs
-===============
-
- The correct address for reporting bugs found in gdb is
-"bug-gdb@gnu.org". Please email all bugs, and all requests for help
-with GDB, to that address. Please include the GDB version number

+Reporting Bugs in GDB
+=====================
+
+ There are several ways of reporting bugs in GDB. The prefered
+method is to use the World Wide Web:
+
+ http://www.gnu.org/software/gdb/bugs/
+
+As an alternative, the bug report can be submitted, via e-mail, to the
+address "bug-gdb@gnu.org".
+
+ When submitting a bug, please include the GDB version number, and
+how you configured it (e.g., "sun4" or "mach386 host,
+i586-intel-synopsys target"). Since GDB now supports so many
different configurations, it is important that you be precise about
-this. If at all possible, you should include the actual banner that
-GDB prints when it starts up, or failing that, the actual configure
-command that you used when configuring GDB.
-
- For more information on how/whether to report bugs, see the GDB
-Bugs section of the GDB manual (gdb/doc/gdb.texinfo) or the
-gdb/CONTRIBUTE file.
-
-Known bugs:
-
- * Under Ultrix 4.2 (DECstation-3100) or Alphas under OSF/1, we have
- seen problems with backtraces after interrupting the inferior out
- of a read(). The problem is caused by ptrace() returning an
- incorrect value for the frame pointer register (register 15 or
- 30). As far as we can tell, this is a kernel problem. Any help
- with this would be greatly appreciated.
-
- * Under Ultrix 4.4 (DECstation-3100), setting the TERMCAP environment
- variable to a string without a trailing ':' can cause GDB to dump
- core upon startup. Although the core file makes it look as though
- GDB code failed, the crash actually occurs within a call to the
- termcap library function tgetent(). The problem can be solved by
- using the GNU Termcap library.
-
- Alphas running OSF/1 (versions 1.0 through 2.1) have the same buggy
- termcap code, but GDB behaves strangely rather than crashing.
-
- * On DECstations there are warnings about shift counts out of range in
- various BFD modules. None of them is a cause for alarm, they are actually
- a result of bugs in the DECstation compiler.
-
- * Notes for the DEC Alpha using OSF/1:
- The debugging output of native cc has two known problems; we view these
- as compiler bugs.
- The linker miscompacts symbol tables, which causes gdb to confuse the
- type of variables or results in `struct <illegal>' type outputs.
- dbx has the same problems with those executables. A workaround is to
- specify -Wl,-b when linking, but that will increase the executable size
- considerably.
- If a structure has incomplete type in one file (e.g., "struct foo *"
- without a definition for "struct foo"), gdb will be unable to find the
- structure definition from another file.
- It has been reported that the Ultrix 4.3A compiler on decstations has the
- same problems.
-
- * Notes for Solaris 2.x, using the SPARCworks cc compiler:
- You have to compile your program with the -xs option of the SPARCworks
- compiler to be able to debug your program with gdb.
- Under Solaris 2.3 you also need patch 101409-03 (Jumbo linker patch).
- Under Solaris 2.2, if you have patch 101052 installed, make sure
- that it is at least at revision 101052-06.
-
- * Under Irix 5 for SGIs, you must have installed the `compiler_dev.hdr'
- subsystem that is on the IDO CD, otherwise you will get complaints
- that certain files such as `/usr/include/syms.h' cannot be found.
-
- * Under Irix 6 you must build with GCC. The vendor compiler reports
- as errors certain assignments that GCC considers to be warnings.
-
- GDB can produce warnings about symbols that it does not understand.
-By default, these warnings are disabled. You can enable them by
-executing `set complaint 10' (which you can put in your ~/.gdbinit if
-you like). I recommend doing this if you are working on a compiler,
-assembler, linker, or GDB, since it will point out problems that you
-may be able to fix. Warnings produced during symbol reading indicate
-some mismatch between the object file and GDB's symbol reading code.
-In many cases, it's a mismatch between the specs for the object file
-format, and what the compiler actually outputs or the debugger
-actually understands.

Graphical interface to GDB -- X Windows, MS Windows
Several graphical interfaces to GDB are available. You should
check:

for an up-to-date list.
Emacs users will very likely enjoy the Grand Unified Debugger mode;

Writing Code for GDB
Running the testsuite requires the prior installation of DejaGNU,
which is generally available via ftp. The directory
-ftp://sourceware.cygnus.com/pub/dejagnu/ will contain a recent
-snapshot. Once DejaGNU is installed, you can run the tests in one of
-the following ways:
+ftp://sources.redhat.com/pub/dejagnu/ will contain a recent snapshot.

runtest -tool gdb GDB=../gdb (or GDB=<somepath> as appropriate)
+When using a `make'-based method, you can use the Makefile variable
+`RUNTESTFLAGS' to pass flags to `runtest', e.g.:
+
+ make RUNTESTFLAGS=--directory=gdb.cp check
+
+If you use GNU make, you can use its `-j' option to run the testsuite
+in parallel. This can greatly reduce the amount of time it takes for
+the testsuite to run. In this case, if you set `RUNTESTFLAGS' then,
+by default, the tests will be run serially even under `-j'. You can
+override this and force a parallel run by setting the `make' variable
+`FORCE_PARALLEL' to any non-empty value. Note that the parallel `make
+check' assumes that you want to run the entire testsuite, so it is not
+compatible with some dejagnu options, like `--directory'.
+
The last method gives you slightly more control in case of problems
with building one or more test executables or if you are using the
testsuite `standalone', without it being part of the GDB source tree.
See the DejaGNU documentation for further details.

+Copyright and License Notices
+=============================
+
+Most files maintained by the GDB Project contain a copyright notice
+as well as a license notice, usually at the start of the file.
+
+To reduce the length of copyright notices, consecutive years in the
+copyright notice can be combined into a single range. For instance,
+the following list of copyright years...
+
+ 1986, 1988, 1989, 1991-1993, 1999, 2000, 2007, 2008, 2009, 2010, 2011
+
+... is abbreviated into:
+
+ 1986, 1988-1989, 1991-1993, 1999-2000, 2007-2011
+
+Every year of each range, inclusive, is a copyrightable year that
+could be listed individually.
