\`configure' configures this package to adapt to many kinds of systems.
 
Usage: $0 [OPTION]... [VAR=VALUE]...
 
To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE. See below for descriptions of some of the useful variables.
 
Defaults for the options are specified in brackets.
 
Configuration:
-h, --help display this help and exit
--help=short display options specific to this package
--help=recursive display the short help of all the included packages
-V, --version display version information and exit
-q, --quiet, --silent do not print \`checking...' messages
--cache-file=FILE cache test results in FILE [disabled]
-C, --config-cache alias for \`--cache-file=config.cache'
-n, --no-create do not create output files
--srcdir=DIR find the sources in DIR [configure dir or \`..']

cat <<_ACEOF
Installation directories:
--prefix=PREFIX install architecture-independent files in PREFIX
[$ac_default_prefix]
--exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
[PREFIX]
 
By default, \`make install' will install all the files in
\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
an installation prefix other than \`$ac_default_prefix' using \`--prefix',
for instance \`--prefix=\$HOME'.
 
For better control, use the options below.
 
Fine tuning of the installation directories:
--bindir=DIR user executables [EPREFIX/bin]
--sbindir=DIR system admin executables [EPREFIX/sbin]
--libexecdir=DIR program executables [EPREFIX/libexec]
--datadir=DIR read-only architecture-independent data [PREFIX/share]
--sysconfdir=DIR read-only single-machine data [PREFIX/etc]
--sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
--localstatedir=DIR modifiable single-machine data [PREFIX/var]
--libdir=DIR object code libraries [EPREFIX/lib]
--includedir=DIR C header files [PREFIX/include]
--oldincludedir=DIR C header files for non-gcc [/usr/include]
--infodir=DIR info documentation [PREFIX/info]
--mandir=DIR man documentation [PREFIX/man]

Program names:
--program-prefix=PREFIX prepend PREFIX to installed program names
--program-suffix=SUFFIX append SUFFIX to installed program names
--program-transform-name=PROGRAM run sed PROGRAM on installed program names
 
System types:
--build=BUILD configure for building on BUILD [guessed]
--host=HOST cross-compile to build programs to run on HOST [BUILD]
--target=TARGET configure for building compilers for TARGET [HOST]

Some influential environment variables:
CC C compiler command
CFLAGS C compiler flags
LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
nonstandard directory <lib dir>
CPPFLAGS C/C++ preprocessor flags, e.g. -I<include dir> if you have
headers in a nonstandard directory <include dir>
CPP C preprocessor
 
Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.

"\|]" +.PP +.B gdbserver +.RB tty +.B --attach +.RB PID +.ad b +.SH DESCRIPTION +GDBSERVER is a program that allows you to run GDB on a different machine +than the one which is running the program being debugged. + +Usage (server (target) side): + +First, you need to have a copy of the program you want to debug put onto +the target system. The program can be stripped to save space if needed, as +GDBserver doesn't care about symbols. All symbol handling is taken care of by +the GDB running on the host system. + +To use the server, you log on to the target system, and run the `gdbserver' +program. You must tell it (a) how to communicate with GDB, (b) the name of +your program, and (c) its arguments. The general syntax is: + + target> gdbserver COMM PROGRAM [ARGS ...] + +For example, using a serial port, you might say: + + target> gdbserver /dev/com1 emacs foo.txt + +This tells gdbserver to debug emacs with an argument of foo.txt, and to +communicate with GDB via /dev/com1. Gdbserver now waits patiently for the +host GDB to communicate with it. + +To use a TCP connection, you could say: + + target> gdbserver host:2345 emacs foo.txt + +This says pretty much the same thing as the last example, except that we are +going to communicate with the host GDB via TCP. The `host:2345' argument means +that we are expecting to see a TCP connection from `host' to local TCP port +2345. (Currently, the `host' part is ignored.) You can choose any number you +want for the port number as long as it does not conflict with any existing TCP +ports on the target system. This same port number must be used in the host +GDBs `target remote' command, which will be described shortly. Note that if +you chose a port number that conflicts with another service, gdbserver will +print an error message and exit. + +On some targets, gdbserver can also attach to running programs. +This is accomplished via the --attach argument. The syntax is: + + target> gdbserver COMM --attach PID + +PID is the process ID of a currently running process. It isn't +necessary to point gdbserver at a binary for the running process. + +Usage (host side): + +You need an unstripped copy of the target program on your host system, since +GDB needs to examine it's symbol tables and such. Start up GDB as you normally +would, with the target program as the first argument. (You may need to use the +--baud option if the serial line is running at anything except 9600 baud.) +Ie: `gdb TARGET-PROG', or `gdb --baud BAUD TARGET-PROG'. After that, the only +new command you need to know about is `target remote'. It's argument is either +a device name (usually a serial device, like `/dev/ttyb'), or a HOST:PORT +descriptor. For example: + + (gdb) target remote /dev/ttyb + +communicates with the server via serial line /dev/ttyb, and: + + (gdb) target remote the-target:2345 + +communicates via a TCP connection to port 2345 on host `the-target', where +you previously started up gdbserver with the same port number. Note that for +TCP connections, you must start up gdbserver prior to using the `target remote' +command, otherwise you may get an error that looks something like +`Connection refused'. +.SH OPTIONS +You have to supply the name of the program to debug +and the tty to communicate on; the remote GDB will do everything else. +Any remaining arguments will be passed to the program verbatim. +.SH "SEE ALSO" +.RB "`\|" gdb "\|'" +entry in +.B info\c +\&; +.I +Using GDB: A Guide to the GNU Source-Level Debugger\c +, Richard M.

It can be used to +control the execution of a program on a target system from a GDB on a different +host. GDB and GDBserver communicate using the standard remote serial protocol +implemented in remote.c, and various *-stub.c files. They communicate via +either a serial line or a TCP connection. + +For more information about GDBserver, see the GDB manual. + +Usage (server (target) side): + +First, you need to have a copy of the program you want to debug put onto +the target system. The program can be stripped to save space if needed, as +GDBserver doesn't care about symbols. All symbol handling is taken care of by +the GDB running on the host system. + +To use the server, you log on to the target system, and run the `gdbserver' +program. You must tell it (a) how to communicate with GDB, (b) the name of +your program, and (c) its arguments. The general syntax is: + + target> gdbserver COMM PROGRAM [ARGS ...] + +For example, using a serial port, you might say: + + target> gdbserver /dev/com1 emacs foo.txt + +This tells gdbserver to debug emacs with an argument of foo.txt, and to +communicate with GDB via /dev/com1. Gdbserver now waits patiently for the +host GDB to communicate with it. + +To use a TCP connection, you could say: + + target> gdbserver host:2345 emacs foo.txt + +This says pretty much the same thing as the last example, except that we are +going to communicate with the host GDB via TCP. The `host:2345' argument means +that we are expecting to see a TCP connection from `host' to local TCP port +2345. (Currently, the `host' part is ignored.) You can choose any number you +want for the port number as long as it does not conflict with any existing TCP +ports on the target system. This same port number must be used in the host +GDBs `target remote' command, which will be described shortly. Note that if +you chose a port number that conflicts with another service, gdbserver will +print an error message and exit. + +On some targets, gdbserver can also attach to running programs. This is +accomplished via the --attach argument. The syntax is: + + target> gdbserver --attach COMM PID + +PID is the process ID of a currently running process. It isn't necessary +to point gdbserver at a binary for the running process. + +Usage (host side): + +You need an unstripped copy of the target program on your host system, since +GDB needs to examine it's symbol tables and such. Start up GDB as you normally +would, with the target program as the first argument. (You may need to use the +--baud option if the serial line is running at anything except 9600 baud.) +Ie: `gdb TARGET-PROG', or `gdb --baud BAUD TARGET-PROG'. After that, the only +new command you need to know about is `target remote'. It's argument is either +a device name (usually a serial device, like `/dev/ttyb'), or a HOST:PORT +descriptor. For example: + + (gdb) target remote /dev/ttyb + +communicates with the server via serial line /dev/ttyb, and: + + (gdb) target remote the-target:2345 + +communicates via a TCP connection to port 2345 on host `the-target', where +you previously started up gdbserver with the same port number. Note that for +TCP connections, you must start up gdbserver prior to using the `target remote' +command, otherwise you may get an error that looks something like +`Connection refused'. + +Building gdbserver: + +The supported targets as of November 2006 are: + arm-*-linux* + crisv32-*-linux* + cris-*-linux* + i[34567]86-*-cygwin* + i[34567]86-*-linux* + i[34567]86-*-mingw* + ia64-*-linux* + m32r*-*-linux* + m68*-*-linux* + m68*-*-uclinux* + mips*64*-*-linux* + mips*-*-linux* + powerpc[64]-*-linux* + s390[x]-*-linux* + sh-*-linux* + spu*-*-* + x86_64-*-linux* + xscale*-*-linux* + +Configuring gdbserver you should specify the same machine for host and +target (which are the machine that gdbserver is going to run on. This +is not the same as the machine that gdb is going to run on; building +gdbserver automatically as part of building a whole tree of tools does +not currently work if cross-compilation is involved (we don't get the +right CC in the Makefile, to start with)). + +Building gdbserver for your target is very straightforward. If you build +GDB natively on a target which gdbserver supports, it will be built +automatically when you build GDB. You can also build just gdbserver: + + % mkdir obj + % cd obj + % path-to-gdbserver-sources/configure + % make + +If you prefer to cross-compile to your target, then you can also build +gdbserver that way. In a Bourne shell, for example: + + % export CC=your-cross-compiler + % path-to-gdbserver-sources/configure your-target-name + % make + +Using GDBreplay: + +A special hacked down version of gdbserver can be used to replay remote +debug log files created by gdb. Before using the gdb "target" command to +initiate a remote debug session, use "set remotelogfile " to tell +gdb that you want to make a recording of the serial or tcp session. Note +that when replaying the session, gdb communicates with gdbreplay via tcp, +regardless of whether the original session was via a serial link or tcp. + +Once you are done with the remote debug session, start gdbreplay and +tell it the name of the log file and the host and port number that gdb +should connect to (typically the same as the host running gdb): + + $ gdbreplay logfile host:port + +Then start gdb (preferably in a different screen or window) and use the +"target" command to connect to gdbreplay: + + (gdb) target remote host:port + +Repeat the same sequence of user commands to gdb that you gave in the +original debug session. Gdb should not be able to tell that it is talking +to gdbreplay rather than a real target, all other things being equal. Note +that gdbreplay echos the command lines to stderr, as well as the contents of +the packets it sends and receives. The last command echoed by gdbreplay is +the next command that needs to be typed to gdb to continue the session in +sync with the original session.
