problem with inter-dependant classes

[proven olive]

I have two classes (vec2 and vec3) which rely on each other.
vec2 is declared before vec3 in the header file.
I get this error when attempting to return a vec3 from a function in vec2:

vec.hpp:59:5: error: ‘vec3’ does not name a type; did you mean ‘vec2’?
  59 |     vec3 xxx();
     |     ^~~~
     |     vec2

How can I fix this?

You can do something like
struct vec3;
Which essential says "there will be a type called vec3 defined sometime later"

ah

thanks, that worked

There are some restrictions with it, but that is step 1

Basically if ever you see an error mentioning incomplete types, that is what it refers to
