C++ GdExtension Project as Library?

[solid bolt]

This may seem like a silly question but is it possible to make a gdextension basically a library?

Context: I am converting one of my chess-like board games into a godot project and separating the client and server code and have a git submodule for both projects that has the shared classes for the data of the game (currently written in gdscript). For performance reasons I am planning on migrating this to c++ and the documentation for GdExtension is clear on making a project but not a subproject and now I am wading through errors in the godot-cpp project that don't appear in my client or server projects.

So is there a way to make the basic library project I am hoping to use as a shared resource or is a different strategy needed?

gdextensions are already libraries

they're not tied to your godot project, you can toss them into a separate git repo just like that

and after you compile them, you just need to make sure the compiled files are in the godot project or moved into it, and that the godot project contains a text file with a name ending in .gdextension that tells godot what compiled library files to load

one thing you could do for example is structuring the extension like an addon, so you can clone it as a submodule inside res://addons in all projects you want to use that extension

and include the text file in there, pointing to the bin folder where the dll/so/dylib files are generated

if you want a quick start you can use https://github.com/godotengine/godot-cpp-template as the starting point of your extension
