[4.0] Unable to compile C++ with SCons, missing binding_generator

[RayHammer]

I've migrated my project recently from 3.5 to 4.0 and while trying to compile libraries I get the following error:

ModuleNotFoundError: No module named 'binding_generator':
  File "/home/rayhammer/Documents/Godot/GunPower/SConstruct", line 7:
    from binding_generator import scons_generate_bindings, scons_emit_files

I'm not sure what's wrong since I followed the guide, so any help would be appreciated

Try updating SCons or something. Mine is v4.4.0 and I have managed to build the GDExtensionExample.

I believe this is because the SConstruct file listed in the documentation here is incorrect. Instead of the one listed in the documentation, this one should be used: https://github.com/godotengine/godot-cpp-template/blob/main/SConstruct

The example SConstruct in the docs should work. I used it a couple months ago in a live GDExtension demo where it worked, and looking at the code now, it seems fine to me.

The one in godot-cpp-template is more advanced for sure, and that project is a great place to start, but it shouldn't be required.

Returning to the original problem:

I've migrated my project recently from 3.5 to 4.0 and while trying to compile libraries I get the following error:

This could be a matter of not pulling in the updated version of the godot-cpp Git submodule?

In any case, we'd really need to see more of your project to know for sure. Please share an MRP or more details!
