====== GDB remote debugging ======

===== Overview =====
You can use the [[http://www.gnu.org/software/gdb/|GNU Project Debugger (GDB)]] to debug gPXE.  In order to do this, you must either have two computers or run gPXE under virtualization (e.g. [[http://bellard.org/qemu/|QEMU]]).

When using two computers, one computer will run gPXE while the other will run GDB.  GDB communicates with gPXE over the serial port.  You will need a null modem serial cable to connect the two computers.

===== Building with GDB enabled =====
Change the following line in ''src/config.h'' to enable GDB remote debugging:
<code>
</code>
