include entt.hpp in two module cause a crash

[armorhu]

here is my problem。
In my project，I have two module，both want use same entt_registry.
So I share the same entt::registry instance with them.
But , when i add component i found type_id of diffecnent component will be same.

in module a
registry->emplace ,
const auto index = type_seq::value();
index = 0;

in module b
registry->emplace ,
const auto index = type_seq::value();
index = 0; // same as module a

and i think this is because

both module has it's own static varible.

so what can i do...

You've a few options:

• Wait until v3.9, it solves this problem.
• Use master (not the single include file), this problem is already solved upstream.
• Generate your own single include file from master (see scripts/amalgamate.py).

😂 let me fix it, you're right. This is just a changelog preview but yeah, I should keep it in sync until it's official.
master is not v3.8, the v3.8 tag is v3.8 and the v3.8.x branch contains the last version for this release, that is v3.8.1.
master is master, it contains all the changes that are meant to be part of the upcoming v3.9 at the moment. 🤷‍♂️

I think you need python3 actually.
