error: expected constructor, destructor, or type conversion before ';' token

Simply asked: What is going wrong here?!

class c {
  public:
  static void v() {
    int var = 0;
  }

  static int i() {
    return 1;
  }
};

c::i(); // Throws error message
c::v(); // Also throws error message

void setup() {
}

void loop() {
}

The error message(s) are:

Compiling sketch...

/tmp/698769749/CompilingTests/CompilingTests.ino:12:7: error: expected constructor, destructor, or type conversion before ';' token

c::i();

^

/tmp/698769749/CompilingTests/CompilingTests.ino:13:7: error: expected constructor, destructor, or type conversion before ';' token

c::v();

^

exit status 1

What should this error message tell me?

One of the problems that stands out is that your functions don't have public access.

Statements c::i() and c::v() are not allowed in the global scope, they should be enclosed inside a function. Also, those static member functions should be declared public in order to be accessible outside c:

struct c {

  static void v() {
    int var = 0;
  }

  static int i() {
    return 1;
  }
};

void g()
{
    c::i();
    c::v();
}

void setup() {
}

void loop() {
}
