A quick overview of starting the debugger

To debug an application, do the following:

  1. Start GDB, but don't specify the application as an argument:

    gdb

  2. Load the symbol information for the application:

    file my_application

  3. If you're debugging remotely, set the target:

    target qnx com_port_specifier | host:port | pty

  4. If you're debugging remotely, send the application to the target:

    upload my_application /tmp/my_application

  5. Set any breakpoints. For example, to set a breakpoint in main():

    set break main

  6. Start the application:

    run
