Debugging with GDB
Before you debug with GDB, you must compile your program with the option -ggdb. Use the
following steps to do this:
1.
To debug a program called
hello-debug
on the target, use the command:
#gdbserver 192.168.4.142:2000 hello-debug
This is where 2000 is the network port number on which the server waits for a connection
from the client. This can be any available port number on the target. Following this are the
name of the program to be debugged (hello-debug), plus that program’s arguments. Output
similar to the following will be sent to the console:
Process hello-debug created; pid=38
2.
Use the following command on the host to change to the directory that contains
hello-debug
:
cd /my_work_directory/myfilesystem/testprograms
3.
Enter the following command:
#ddd --debugger xscale_be-gdb hello-debug &
4.
Enter the following command at the GDB, DDD command prompt:
Target remote 192.168.4.99:2000
The command produces another line of output on the target console, similar to the following:
Remote debugging using 192.168.4.99:2000
192.168.4.99 is the machine’s IP address, and 2000 is the port number. You can now begin
debugging in the host environment using the interface provided by DDD.
5.
Set a breakpoint on main by double clicking, or entering b main on the command line.
6.
