1.6.6. Debugging Using the gdb Client on the Host

  1. Run the gdb client on the host: 
    gdb-multiarch ./factorial.out
Process ./factorial.out created; pid = 229
Listening on port 8080
  2. Connect gdb to the target.
    Note: This example uses localhost:3624 instead of 192.168.0.9:8080 as shown in the VLAN port mapping found in the "Network Connectivity" section. 
    (gdb) target remote localhost:3624
Remote debugging using localhost:3624
warning: Unable to find dynamic linker breakpoint function.
GDB will be unable to debug shared library initializers
and track explicitly loaded dynamic code.
0x76fcfb00 in ?? ()
  3. Use the following gdb sample commands to debug the code:
    • b main: Set a breakpoint at the main function
    • c: Continue until the breakpoint is hit
    • s: Step one instruction
    • b 14: Insert a breakpoint at line 14
    • c typed multiple times: Run through iterations of the loop
    • l: List code

    The host console looks similar to the view below:
