Stuck on dynamic linker


Okay I am still new at linux and I figured to help me learn more about linux I figured I would attempt to build 1 my self.

So I am using the LFS BOOK and I have came to an area where I am confused.

Also be aware of the name of the platform's dynamic linker, often referred to as the dynamic loader (not to be confused with the standard linker ld that is part of Binutils). The dynamic linker provided by Glibc finds and loads the shared libraries needed by a program, prepares the program to run, and then runs it. The name of the dynamic linker for a 32-bit Intel machine will be ld-linux.so.2. A sure-fire way to determine the name of the dynamic linker is to inspect a random binary from the host system by running: readelf -l <name of binary> | grep interpreter and noting the output. The authoritative reference covering all platforms is in the shlib-versions file in the root of the Glibc source tree.
I am using slackware 32bit and i'm not sure what kind of binary package to use or where it is on slackware for readelf -l <name of binary> | grep interpreter.

So what is the best file to put in?

Sorry to be a bug but I would like to learn on how to do this.

I think command should be
Code:
readelf -l <name of binary> | grep -i interpreter
Also keep in mind, that it will work ONLY for dynamically linked executable, for statically linked (like /sbin/ldconfig) you'll get no output
