How to debug a remote Linux binary?

Here is the situation:

I have a linux binary file that breaks. No log files, trace files, etc. I need to be able to connect a debugger to it (I have a source locally) and track the error.

What is the easiest and most effective way to solve this problem?

Remote debugging is quite simple: on the target platform, launch the application using GDBserver, specifying the host and port to listen for the incoming TCP connection:

  gdbserver HOST:PORT PROG [ARGS ...]

On the development workstation, start the GDB gateway:

  powerpc-7450-linux-gnu-gdb PROG

Be sure to specify an unused executable. In the GDB console, type:

  target remote HOST:PORT
  break main
  continue

- GDB GDBserver
