About dynamic and external symbols
by P J P
Hello there,
I was wondering what is difference between dynamic and external symbols,
ie. nm -D <ELF> and nm -g <ELF> output?
Also if an <ELF> file is stripped, -g does not show any external symbols.
Plus there are dynamic symbols, some of which are defined and some are
undefined(UNDEF).
Thank you.

Hi, I was trying to build elfutils on i686-F12 machine. It fails with

Where could I disable -Werror?
