Compiling TheForgottenServer 0.3.5 ERROR

[Zodia]

Below is the only information I get when I try to compile.

I can understand that there is a problem with:

"/usr/include/c++/7/ostream:196: undefined reference to `ProtocolAdmin::rotocolAdminCount'"

Even though I don't understand.

Maybe missing some lib? Incorrect libraries? I appreciate the personal help!

Now I am totally lost.
I sincerely thank you if you decide to take 1 minute of your time to give me a light.
