gdb won't let me set a breakpoint when i use a relative file name.  i have to 
cd into the dir where the file is to make a break point.  its kinda annoying.  
am i doing something wrong or is this how its suppose to be?

ex output:

(gdb) pwd
Working directory /home/cjb/projects/cs378/linux-2.4.19.
(gdb) b arch/um/kernel/hostandtime.c:9
No source file named arch/um/kernel/hostandtime.c.
(gdb) cd arch/um/kernel/             
Working directory /home/cjb/projects/cs378/linux-2.4.19/arch/um/kernel.
(gdb) b hostandtime.c:9
Breakpoint 4 at 0xa0074187: file hostandtime.c, line 9.

thanks for the help,
-- christopher

I've tried all manner of experiments, including (gasp!) reading the
GDB manual, but I can't seem to get line number info compiled into my
executables.  Check this out:

# gcc -o hello -g -g3 -ggdb -ggdb3 -static hello.c
# /usr/local/bin/gdb hello

(gdb) list hello.c:26
21	{
22	  int j;
23	
24	  for (i=0; i<2; i++) {
25	    for (j=0; j<2; j++) {
26	      printf ("Hello, World! (%d,%d)\n", i, j);
27	    }
28	  }
29	
30	  return 0;
(gdb) b hello.c:26
No line 26 in file "hello.c".
(gdb) 

What gives?!?  GDB can list line 26 of hello.c.  But it claims there
is 'No line 26 in file "hello.c".' !?!

What does "info source" say?

Daniel> What does "info source" say?

(gdb) info source
Current source file is hello.c
Compilation directory is /root
Located in /root/hello.c
Contains 31 lines.
Source language is c.
Compiled with DWARF 2 debugging format.
Does not include preprocessor macro info.
(gdb) d'oh!

OK, looks like I used the wrong debug flags during compile.
D'oh again.

Thanks,
Dave

Does that mean you can "break hello.c:26" now?  The session you posted
before should have worked...

Yes, now I can.

Breaking at a line number did not work before.  Now it does.  Thanks!
