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
