issue compiling single header

[skreamz]

Hi I'm using the single header of entt with vc2022 using the 'Preview - Features from the Latest C++ Working Draft (/std:c++latest) 'language standard, and I've the following errors when compiling.

Severity Code Description Project File Line Suppression State
Error (active) E0526 a parameter may not have void type Engine D:\Projects\Engine\libraries\entt\entt.hpp 15290
Error (active) E0018 expected a ')' Engine D:\Projects\Engine\libraries\entt\entt.hpp 15290

Error C2334 unexpected token(s) preceding '{'; skipping apparent function body (compiling source file src\components\Component.cpp) Engine D:\Projects\Engine\libraries\entt\entt.hpp 13116

and a whole load more of the same. the first 2 are for the following.

template<typename Ret, typename... Args>
delegate(Ret(*)(const void *, Args...), const void *= nullptr)->delegate<Ret(Args...)>;

any help would be grateful.
Thank you.

I don't have a working copy of VS2022 at the moment but this looks a lot like the C++ version to use doesn't propagate to the imported library.
How do you include EnTT in your codebase? A VS solution? CMake? What else?

[skreamz]

VS solution via addition include directories option. I have a single include file called headers.h which include all libraries including entt.hpp, I've also tried it with a new/blank project, same errors.

Is your project online? I can clone it when I'm back at work and let you know what's wrong.
