Hello All,

I see a core dump in my application and i tried to setup GDB debug enviroment (note that, few shared binaries compiled with -g option with gcc and few shared binaries are not compiled with -g option) and i see the following error message in GDB debugger.

<<
no debugging symbols found)
(no debugging symbols found)
[Thread debugging using libthread_db enabled]
[New Thread 1075400832 (LWP 1524)]

(gdb) c
Continuing.

Can any one through some light on this issue, Please help me to understand.

Thanks & Regards

The command:
file core_fileName
will give the binary that produced that core file.
Can you submit the output of:
1)
file "file binary_name_obtained_from_file_core_fileName"
2)
ldd "file binary_name_obtained_from_file_core_fileName"
