The error 'godot error loading extension' in Godot Engine typically occurs when there is an issue with adding or using a native script or GDNative extension. There can be several reasons for this error:
Missing Dependencies: The GDNative library depends on other dynamically linked libraries that might not be present or correctly installed on the system.
Incorrect Path: If the path to the GDNative library or its associated .gdns file is incorrect, Godot will not be able to load the extension.
Incompatible Versions: The version of the GDNative library may not be compatible with the version of the Godot Engine being used.
Corrupted Files: The GDNative library or .gdns file might be corrupted or improperly generated.
Permissions Issues: There could be insufficient permissions to access the GDNative library files on the file system.
API Mismatch: There might be an API mismatch due to changes in the Godot Engine's API and the compiled GDNative code, which often happens after an engine update.
Solution - Here's How To Resolve It
To resolve the 'godot error loading extension' follow these steps:
Check Dependencies: Ensure that all the required dependencies for the GDNative library are installed on your system.
Correct Paths: Verify that the paths to your GDNative library and .gdns files are correct in your Godot project settings.
Version Compatibility: Make sure that the version of the GDNative library is compatible with your current version of Godot Engine. Rebuild the library if necessary using the correct version of the API.
Re-download or Rebuild: If the files are corrupted, try re-downloading or rebuilding the GDNative library and .gdns files.
File Permissions: Confirm that you have the right file permissions set to read and execute the files.
Update GDNative Code: In case of an API mismatch, update the source code of your GDNative library to match the current Godot API and recompile it.
In addition to these steps, consulting the documentation for the specific GDNative extension being used, checking for known issues on the project's repository, or seeking help from the community through forums and Q&A sites can also be beneficial in resolving the issue.
