Gdbserver Error

target extended-remote—but without linking in the usual debugging stub. gdbserver is not a complete replacement for the debugging stubs, because it requires essentially the same operating-system facilities that gdb itself does.
Gdbserver Example
In fact, a system that can run gdbserver to connect to a remote gdb target remote gdb could also run gdb locally! gdbserver is sometimes useful nevertheless, because it is a much smaller program than error with command gdb version windows gdb itself. It is also easier to port than all of gdb, so you may be able to get started more quickly on a new system by using gdbserver. Finally, if you

develop code for real-time systems, you may find that the tradeoffs involved in real-time operation make it more convenient to do as much development work as possible on another system, for example by cross-compiling. You can use gdbserver to make a similar choice for debugging. gdb and gdbserver communicate via either a serial line or a TCP connection, using the standard gdb remote serial protocol.
Gdb Remote Protocol
Warning: gdbserver does not have any built-in security. Do not run gdbserver connected to any public network; a gdb connection to gdbserver provides access to the target system with the same privileges as the user running gdbserver. 20.3.1 Running gdbserver Run gdbserver on the target system. You need a copy of the program you want to debug, including any libraries it requires. gdbserver does not need your program's symbol table, so you can strip the program if necessary to save space. gdb on the host system does all the symbol handling. To use the server, you must tell it how to communicate with gdb; the name of your program; and the arguments for your program. The usual syntax is: target> gdbserver comm program [ args ... ] comm is either a device name (to use a serial line), or a TCP hostname and portnumber, or - or stdio to use stdin/stdout of gdbserver. For example, to debug Emacs with the argument ‘foo.txt’ and communicate with gdb over the serial port /dev/com1: target> gdbserver /dev/com1 emacs foo.txt gdbserver waits passively for the host gdb to communicate with it. To use a

save space if needed, as GDBserver doesn’t care about symbols. All symbol handling is taken care of by the GDB install gdbserver running on the host system. To use the server, you log on to the target system, and run the ‘gdb- server’ program. You must tell it (a) how to communicate with GDB, https://sourceware.org/gdb/onlinedocs/gdb/Server.html (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 http://linuxcommand.org/man_pages/gdbserver1.html 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 neces- sary to point gdbserver at a binary for the running process. Usage (host side): You need an unstripped copy of the target program on yo

Run gdb --version within your terminal. –Till Jan 13 '14 at 1:27 In my experience this is eclipse bug related to system PATH. Check if it's valid or if you can simplify it. –dbrank0 Jan 13 '14 at 10:40 Yes, I have gdb, instead it changes its name to ggdb, but I still cannot debug –user3000888 Jan 14 '14 at 22:10 Are you on OS X Mavericks? Also, how do you know it's changing the name? What do you mean by that? –Neil Traft Jan 24 '14 at 2:34 add a comment| 4 Answers 4 active oldest votes up vote 11 down vote You can fix this by specifying the full path to gdb. You can do this separately for each debug configuration, and you can also set the default gdb location in the preferences under C/C++ > GDB.

Until now, debugging with the J-Link probe in Eclipse was done via the GDB Hardware Debugging plug-in. For experimental projects it was more or less ok, but for serious development it was quite tedious. The missing features, that were added to this plug-in, are: transparent integration of the GDB server, automatically started/stopped for each debug session advanced graphical user interface to configure most GDB client and GDB server SEGGER specific options transparent integration of the semihosting and Serial Wire Viewer (SWV) window as a standard Eclipse console a functional restart button, to reset the target and restart the debugging session, without having to rewrite the executable image direct use of project toolchain definition (prefix, suffix, path) to simplify configuration of the GDB client macro based J-Link folder path definition, for simplified management of the GDB server location when upgrades to new SEGGER versions are released support for SWO registers configuration to match a given system clock frequency Prerequisites Before being able to use the J-Link probe with the GNU ARM Eclipse plug-ins, you must separately install: the J-Link debugging plug-in the GDB debugger (client) application, as part of a GNU toolchain the SEGGER J-Link GDB server and drivers.
