Subject: A very basic HelloWorld with jextract and panama
This question is so basic that I must be missing something. Sorry if that's a dumb rookie question.

I have the following C++ code:

    #include <iostream>

    using namespace std;

    void sayHello() {
        cout << "Hello, Panama!" << endl;
    }

Great!!!

Now how do I go about calling the "sayHello()" C++ method from Java using jextract and panama?

I can use Linux or Mac, you choose. And I have jextract built on both machines.

That's easy and straightforward with JNI, JNA and JNR. But not with Panama? :(

Your help clarifying this issue will be greatly appreciated!
