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
-over time--for example don't try to build gdb with a copy of bfd from
-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.

+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:
-
- 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
+ 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-5.0
- ./configure
- make
- cp gdb/gdb /usr/local/bin/gdb (or wherever you want)
+ cd gdb-VERSION
+ ./configure
+ make
+ cp gdb/gdb /usr/local/bin/gdb (or wherever you want)
However, we recommend that an empty directory be used instead.
This way you do not clutter your source tree with binary files
You can build GDB in any empty build directory:
-
- mkdir build
- cd build
- <full path to your sources>/gdb-5.0/configure
- make
+ 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
-the Info file by typing:

+typing:
- cd gdb/doc
- make info
+ cd gdb/doc

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.
+`gdb-VERSION/texinfo' directory.
If you have TeX and a DVI printer program installed, you can typeset

- make gdb.dvi

+For this to work, you will need the PDFTeX package to be installed.
Installing GDB

The GDB distribution includes all the source code you need for GDB in
-a single directory, whose name is usually composed by appending the
-version number to `gdb'.

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

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,
+as `gdb-VERSION' (or in a separate configured directory configured with

- hosts.

-`HOST ...'
- Same as `--host=HOST'. If you omit this, GDB will guess; it's

+`--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.

-Kernel debugging
-=================

Remote debugging
=================

+allows remote debugging for Unix applications. GDBserver is only
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-nindy.c Intel 960 "Nindy"
- remote-nrom.c NetROM ROM emulator
- remote-os9k.c PC running OS/9000
- remote-rdi.c ARM with Angel monitor
- remote-rdp.c ARM with Demon monitor
remote-sds.c PowerPC SDS monitor
remote-sim.c Generalized simulator protocol
- remote-st.c Tandem ST-2000 monitor
- remote-udi.c AMD 29000 using the AMD "Universal Debug Interface"
- 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:
- http://sourceware.cygnus.com/gdb/#gui
+ http://www.gnu.org/software/gdb/links/
for an up-to-date list.
Emacs users will very likely enjoy the Grand Unified Debugger mode;

-new kind of gdb-mode should load gdb/gdba.el into GNU Emacs 19.25 or
-later. Comments on this mode are also welcome.

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.
+Once DejaGNU is installed, you can run the tests in one of the
+following ways:

+ (1) cd gdb-VERSION
make check-gdb
or
- (2) cd gdb-5.0/gdb

+ (3) cd gdb-VERSION/gdb/testsuite
make site.exp (builds the site specific file)
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
