unresolved external from library containing many templates and many C++20 modules!

[JUANDENT]

Hi,

I have a library composed of many C++20 modules and when I link with it in an executable I get unresolved external...why?

I am using VS2022 latest Preview version because ordinary version would say internal compiler error and working everything in C++ latest!!



Please some light?

Not enough information in your post to give you a meaningful response.

When this happens to me, I find the most common cause is I have a class with a function declaration, but the implementation of the function is missing.
