Unable to compile a C++ program from Rosetta Code that uses Primesieve

[Kenneth Wolcott]

Hi;

Unable to compile a C++ program from Rosetta Code that uses Primesieve

https://rosettacode.org/wiki/Anaprimes

port installed | grep primesieve
  primesieve @12.4_0 (active)

Am I missing something critical like an environment variable that
specifies /opt/local/lib, or something like that?

Do I need a link command with my clang++ command?

clang++ -o ./anaprimes ./anaprimes.cpp

Undefined symbols for architecture arm64:

    46        anaprimes[get_digits(prime)].push_back(prime);
    47    }
    48 }

Thanks in advance for the help.
