"\|]" -.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.
