I'm reading "An Introduction to GCC" from this site:
http://www.network-theory.co.uk/docs...tro/index.html
I'm reading the "Examining Core Files" section.
http://www.network-theory.co.uk/docs...cintro_38.html
This is their example output when running "gdb a.out core":
Quote:
$ gdb a.out core
Core was generated by `./a.out'.

When I originally ran it, the lines that said "Reading symbols from /lib/*" said something along the lines of "debugging symbols not found". I fixed this by installing the "libc6-dbg" package. Now my output looks like this:

Do you know which package I should install to get rid of this warning message? Some configuration, maybe?
gdb/Core Dump: "warning: Can't read pathname for load map: Input/output error."
