In C++ you can not access a non static class member from a static method. Make it a normal method and try like below:- Else declare pub as static member Also refer to the below answer C++ static member functions and variables
If you come from a class-based, statically typed object-oriented language (like Java, C++ or C#) I assume that you are trying to create a variable or method associated to a “type” but not to an instance. An example using a “classical” approach, with constructor functions maybe could help you to catch the concepts of basic OO JavaScript: … Read more
Can someone explain the difference between a static and const variable?
Variables declared inside the class definition, but not inside a method are class or static variables: As @millerdev points out, this creates a class-level i variable, but this is distinct from any instance-level i variable, so you could have This is different from C++ and Java, but not so different from C#, where a static member can’t be accessed using … Read more
The Pythonic way to create a static class is simply to declare those methods outside of a class (Java uses classes both for objects and for grouping related functions, but Python modules are sufficient for grouping related functions that do not require any object instance). However, if you insist on making a method at the … Read more
You can’t call something that doesn’t exist. Since you haven’t created an object, the non-static method doesn’t exist yet. A static method (by definition) always exists.

Variables: static variables exist for the “lifetime” of the translation unit that it’s defined in, and: If it’s in a namespace scope (i.e. outside of functions and classes), then it can’t be accessed from any other translation unit. This is known as “internal linkage” or “static storage duration”. (Don’t do this in headers except for … Read more
static means that the variable or method marked as such is available at the class level. In other words, you don’t need to create an instance of the class to access it. So, instead of creating an instance of Foo and then calling doStuff like this: You just call the method directly against the class, … Read more
