shegonee@ix.netcom.com asked:
% I have a program compiled with the -g option. When I run gdb inside of emacs
% it starts gdb fine but doesn't open a second window with the source code
% in it. Is there anything else I need to do to get gdb inside emacs
% to run and open a second window with the source code file in it?
Use M-x gdb to start gdb. When you get the gud-mode window up, use C-x
2 to split the window, and C-x b to switch the current window back to
your source file. Now, if you set a breakpoint and run the program,
when the breakpoint is hit, you'll see a '=>' pointing to the source
line in your source window.

I find gud-mode quite usable with a large X screen, at least 17" and
1024x768 pixels. Anything smaller just doesn't give you enough info
in the gdb and source windows.
