DDD GDB HELP needed

Hi, I am trying to debug my program using gdb, but I am getting this error for some reason:

(gdb) run test1.init /dev/null
Starting program: /auto/home-scf-27/chunchen/csci565/Lab3/test /dev/null

Program exited normally.
warning: Unable to find dynamic linker breakpoint function.
warning: GDB will be unable to debug shared library initializers
warning: and track explicitly loaded dynamic code.
You can't do that without a process to debug
(gdb)

I know the warning should not matter to my program but I am not sure why it says you can't do that without a process to debug.

The program i am loading is simply a program that prints 0 to 9.
I just wanted to test whether i can see the output in gdb or not.
As you can see, it does not print the output for some reason..

I did compile with -g flag.

Any help would be appreciated ..
thanks

I think the reason I is that the (dynamic) library you are using is stripped. Try a "nm /lib/libc.so.0" and if it doesn't display
any symbols you need to get a non-stripped version.

Mandrake 7.1 was shipped with some stripped libraries.
Hope you are not using that OS.

sunnycoder, the problem was that i was soucing a non-default set of parameters in my .cshrc  
its actually kinda irrevelent to ddd or gdb... but rather environment setting issues.
