Hello! I create blank c++ project for editing in XCode. I create new c++ pawn file. I generate project files for xCode. I wait a long time for indexing project and i have errors:

 ![325826-снимок-экрана-2020-12-28-в-231635.jpg](https://d3kjluh73b9h9o.cloudfront.net/original/4X/8/3/b/83b794dc4bdb98542f0736ad4d66a2a6006bd29a.jpeg)

What can i do to resolve this errors? It’s not code errors, it’s xCode problem, but i do not understand why.  
xcode Version 12.3 (12C33)

Thank you.

The reason for that issue is that macro definitions are missing.  
Check this one, maybe it can help you:
