Here is a patch which allows using the GNU debugger as an alternative to the DOSBox built-in debugger. The built-in debugger may be more convenient to show x86 specific information about execution state, whereas Gdb is useful for C and C++ source level debugging. This patch applies against svn revision 3761. Once applied the configure script can be used with a new option: ./autogen.sh ./configure --enable-debug=gdbserver DOSBox then listen on TCP port 1234 and a Gdb client compiled for x86_64 or i686 targets can be connected: $ gdb (gdb) target remote localhost:1234 The gdb architecture must be set depending on the code your are trying to disassemble (16 or 32 bits), for instance: (gdb) set architecture i8086 (gdb) x/32i $eip Breakpoints and watchpoints are supported and some DOSBox specific features are available through the gdb "monitor" command. This patch adds the following files: - src/debug/gdb_server.cpp file - src/debug/debug_log.cpp - src/debug/debug_helpers.cpp The debug.cpp file has been split in 3 files so that the original file now contains built-in debugger stuff only and debug_log.cpp/debug_helpers.cpp files contain common code used by both built-in and Gdb debuggers. Some variables which were previously local to debug.cpp have been prefixed by DEBUG_ and debug.h has been updated accordingly. Tested under GNU/Linux.
