====== 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> ===== Using GDB remote debugging ===== ===== GDB documentation ===== * [[http://sourceware.org/gdb/current/onlinedocs/gdb_toc.html|Debugging with GDB (official manual)]] * [[http://darkdust.net/files/GDB%20Cheat%20Sheet.pdf|A cheatsheet]], note that there are several others [[http://google.com/search?q=gdb+cheat+sheet|available]]. ===== Getting help ===== You can email the [[https://lists.sourceforge.net/lists/listinfo/etherboot-developers|Etherboot-Developers]] list or ask on the [[http://www.etherboot.org/wiki/contact|IRC channel]].
