Starting gdb

Starting gdb

[Kay Ulbrich]

Hello,

I have a question concerning gdb under Emacs. When debugging, I do the
normal thing, i.e.,

	M-x gdb

and then enter the executable name. After this, in the gdb window, I can
set arguments with the gdb-command "set args".

Are there functions, which enable me to write custom Elisp-functions,
which would do this in one turn, i.e., something like

	M-x debug-myprog

which then would start debugging the desired executable and set the
arguments.

Thus one could write an Elisp-function for frequently needed executables
and argument list combinations.

Thanks for hints!

Kay

Many years ago I did this using a gdb-init file. I don't remember the
exact name, look into gdb documentation, but I surely know that gdb
reads a file in the current directory while starting up. This file can
also contain paths to source files and much more.

T.M.

Hello,

thank you for your suggestion.

It implies an entry in ~/.gdbinit like:

define myprog
  file myprog.exe
  set args --arg val
end

The problem is, that, when starting gdb in Emacs and running this macro,
one nice feature is not realized. This is the automatic opening of the
file containing the main() - function.

I thought, maybe gdb-mode offers some interface ...

Kay,

Do the commands
   break main
   run
help?

Hello Colin,

this helps, i.e., now the file is displayed, with the slight difference,
that now the program is already running.

But as it stops at main, this is no big deal.

Thanks for the suggestion!
