iOS - build failing - 'libffi' patch fails with "hunks failed"

[benjgray]

I'm trying to build the Carvera community controller to run on my iPad so I can test and provide feedback. After a long effort to try a build for iOS (macOS Sequoia, Xcode 16), I've ultimately failed to get the Xcode project to build. This issue occurs even when using the code from the latest iOS-related pull request (#341).

Summary of Steps Taken:

• Cloned the repository and checked out the code from PR Port of new comms protocol from Makera Controller 0.9.12 #341.

• Set up a clean Python 3.11 environment using Poetry.

• Manually edited the kivy_ios/recipes/libffi/__init__.py script to skip the obsolete armv7 architecture.

• Manually created the v3.4.4-fix-xcode-15-build.patch file with the contents from PR Poetry install fix for kivy-ios on Windows (#173) #174 to fix the Assembly code compilation.

Final Error:

Even with all these fixes, the build fails when the script attempts to apply the patch to libffi, with the error:

patching file 'src/aarch64/sysv.S'
1 out of 1 hunks failed--saving rejects to 'src/aarch64/sysv.S.rej'

Does this indicates the downloaded libffi source code does not match the patch file?

I don't seem to be able to get the project buildable for iOS on my system/setup. Could a maintainer please provide a definitive, working build_ios.sh and a verified set of dependency recipes?

Once I get the iOS version running on my iPad, I'd be happy to feature test, etc. Cheers.

Yes, I believe it does.

Unfortunately the iOS version of the Community Controller is unmaintained, the current group of active developers doesn't have iOS experience or the required hardware to attempt to work on it. Sorry, can't help much further.
