Re: Noob question: mv is hard to debug with GDB

[Mike Hodson]

Hello Stéphane,

I suspect you are compiling the source for Coreutils against system
libraries. If so, you should also install the debug symbols or separate
library packages (depending on distro they can be provided somewhat
differently) for the packages you have installed, at least, for the
dependency tree of Coreutils, down to and inclusive of glibc itself.

Otherwise you would have to compile the entire dependency tree of
middleware all the way down to glibc yourself, ala linux-from-scratch
style, likely in a chroot or virtual machine.

Those are the only 2 ways I see it working, one being far easier :)

Hope this helps,

Mike
