gdb-show-main disappeared...

[Denis Golovan]

Hi, all

    I have a trouble using gdb-show-main option in emacs 23.0.60 (cvs version).
It simply lacks gdb-show-main. Any help?

It still seems to be there if you do `C-h v gdb-show-main'.  Note though that
it's not autoloaded so you need to load gdb-ui.el first, e.g., by doing M-x gdb
or M-x load-library<RET> gdb-ui<RET>.

That sounds like a different problem.  How do you mean "it doesn't work"?

The principles of bug reporting are not specific to Emacs.  See the node
"Reporting Bugs" in the Emacs manual. Can you explain what the symptoms are and
exactly how to reproduce it?

  Doesn't show main function and can't be called from mini-buffer (I think command-line below is called so)

  Well, it's easy - try to build emacs from svn source, build any program with debug info and M-x gdb. Next is 
all we discussing. BTW, gdb-ui DOES contain gdb-show-main, I checked.

gdb-show-main is a variable, not a function, so you can't do
M-x gdb-show-main.  From the mini-buffer, gou need to do
M-x set-variable<RET>
Set variable: t (say)

What happens if you set a breakpoint at main and type "run" in the GUD buffer?
If the source doesn't appear in a buffer it probably means that you haven't
compiled with debug information (-g option).

  Yes, you are completely right. My fault :(. It works now :).
