gdb gud won't show source code

gdb gud won't show source code

[viona]

Under Aquamacs 1.7 I try to start gdb, and it opens up all the
windows, like breakpoints, stack etc,
but instead of the buffer with a source code I have a buffer *Buffer
List*. How do I fix that?

Have you thought of sending the question to:

Thanks, I'll try to do that

I've actually did compile with -g. The fact is, that it can't see it
anyway, unless I specify custom output with -o.
I am not sure whether it's supposed behaviour, cause in all tutorials
I've found there are examples with a.out.
Thanks anyway.

The name a.out plays no role. Once gdb has started to run the  
programme to debug, its sources become available. It helps gdb to  
have a .gdbinit file in the directory with the binary to debug. Here  
you can record whether the sources are in a different directory. And  
more things, for example breakpoints.

From the command line, if you do (replace myprog with the name of your
program name):

$ gdb myprog
GNU gdb...

(gdb) list
(gdb) info source

what does Gdb print?

You should get `somthing like':

  Current source file is myprog.c
  Compilation directory is /home/nickrob
  Located in /home/nickrob/myprog.c
  Contains 267 lines.
  Source language is c.
  Compiled with DWARF 2 debugging format.
  Does not include preprocessor macro info.

if you compile with "gcc -g -o myprog myprog.c".

It just means that Emacs (Gdb) can't find the main procedure: you've probably
compiled without the -g option.
