Can you provide the syntax you used when invoking gdb? And any error messages it might have displayed?

Also, which compiler did you use on your C program? and what was the error message when it core dumped?

gdb will only be able to usefully debug the core file if the C application that generated it was built with debugging symbols. If the C application has been stripped, then you are not going to get a lot of sense out of gdb.

The usual method would be to start gdb

# gdb

then type in the command

(gdb) core-file core

this will load the core file

then you need to tell gdb where the C application is

(gdb) file foo

Where foo is the name of your C application. You may also need to tell gdb where any shared libraries can be located.
