GDExtension tutorial uses old parameters for example_library_init()

[dcuny]

The tutorial for GDExtension is here: https://docs.godotengine.org/en/stable/tutorials/scripting/gdextension/gdextension_cpp_example.html

In register_types.cpp, the code for example_library_init() is given as:

GDExtensionBool GDE_EXPORT example_library_init(const GDExtensionInterface *p_interface, const GDExtensionClassLibraryPtr p_library, GDExtensionInitialization *r_initialization) {

However, GDExtensionInterface appears to be replaced by GDExtensionInterfaceGetProcAddress, so the code should instead be:

GDExtensionBool GDE_EXPORT example_library_init(const GDExtensionInterfaceGetProcAddress *p_interface, const GDExtensionClassLibraryPtr p_library, GDExtensionInitialization *r_initialization) {

Already fixed in #7378
Note, that this change will come with Godot 4.1 upwards.

How is this fixed when the documentation page is still displaying the wrong code?

The stable docs that you linked to are for Godot 4.0 -- this change is in Godot 4.1. You can see the updated page here (note "stable" switched for "latest" in the URL):

You are looking at the stable branch. 4.1 is not released yet so it is still in latest: https://docs.godotengine.org/en/latest/tutorials/scripting/gdextension/gdextension_cpp_example.html

Ah, I see the issue now. I picked the second option, because it was shorter:

Alternatively, you can also clone it to the project folder:

mkdir gdextension_cpp_example
cd gdextension_cpp_example
git clone -b master https://github.com/godotengine/godot-cpp

Only you can't "alternately" follow those instructions, because it's going to pull from the master, not from the 4.0.

Perhaps that second section should instead be:

mkdir gdextension_cpp_example
cd gdextension_cpp_example
git clone -b 4.0 https://github.com/godotengine/godot-cpp

Which would prevent clueless newbies like me from making this sort of mistake?

Thanks!

@dcuny Thanks for your suggestion. I personally think on latest it should be the master branch which is shown and only on stable and 4.0 it should be 4.0. That way it would be consistent.There is already a note though as well which points users to use the 4.0 branch.
