Answer 1

The libsrp.a file is a static library; a shared library would be called something like libsrp.so. Here there's an answer that describes a way to to build a shared library from a static library (I've never done this myself though, so can't vouch that it works - good luck!)

UPDATE:

Using nm with the -D argument asks for dynamic symbols (check out man nm) - in the question I linked to the guy was using -D as he was invoking nm on a shared library. Your libsrp.a is a static library, so to see the symbols you should just do

nm libsrp.a

However, I don't think you should need to see the symbols to make use of the answer explaining how to get a shared library; if the answer is correct, you should just have to invoke gcc with the correct arguments. I guess once you've got the shared library you could use nm to see if it has the symbols you expect; in that case you will need the -D argument:

nm -D libsrp.so
