Questions about using openCV and ezdxf with kivy-ios

[Chiho]

Can we use opencv and ezdxf with kivy-ios?

When we writed "import cv2" in code.

We running this exe, showing "ModuleNotFoundError: No module named 'cv2'" on Xcode.

But Same exe running on PC. This exe is running correct.

How can we get opencv and ezdxf to work with kivy-ios?

If you have any explanations on how to do it, please let me know.

The computer environment is described below.

- macOS Big Sur 11.6.1

- Mac mini (Apple M1)

- python 3.9

- cython 0.29.17

- kivy-ios 1.2.1

OpenCV is not pure Python, it needs to be compiled for a specific platform.

kivy-ios compiles for ios with a recipe, there is no recipe for OpenCV.

Thank you for your reply.

Does that mean we need to compile opencv and ezdef recipes for kivy-ios?

Do you have any information on how to make a recipe?

[Robert]

Yes, compile opencv with a recipe, exdef I know nothing about.

I don't have any info, I'm not a kivy-ios user and as far as I can tell there is no documentation.

I can point you to the Android recipe documentation, https://github.com/kivy/python-for-android/blob/develop/doc/source/recipes.rst

But I expect that would only be somewhat helpful.

Generally both here and on Discord requests for help creating recipes goes unanswered.

This is a task for people who can be self supporting.

We will refer to document.

Thank you for information.
