Flutter TFLite Errors

이번 프로젝트에 TFLite패키지를 사용하게 되었다.

세팅 과정에서 겪은 여러가지 디버깅 방법들을 모아본다.

Environment

MacBook Air M1
MacOS Monterey 12.0.1
XCode 13.1
Flutter 2.5.3

에러들

0-1.기본루틴

a) Podfile.lock, Pods folder, .symlinks 폴더 삭제
b) flutter clean
c) flutter run

0-2. Dependency가 바뀌지 않을때

tflite 다운그레이드 할 경우 정작 podfile.lock에 가보면 버전이 그대로였다.
Podfile.lock 자체는 Podfile에 의하여 생기는 파일임으로 lock파일을 바꾸는건 옳지 않은것 같다.
Podfile에서 TensorFlowLiteC에 대해 직접 버전을 정할 수 있다. 이 방법을 사용하자.

tflite의 경우 symlinks/plugins/tflite/ios/tflite.podspec 에서 버전이 표기 되니 원하는 버전이 들어간건지 확인 할 수 있다.


생성된 lock파일에서도 버전을 확인 할 수 있다.

1.fatal error: 'Flutter/Flutter.h' file not found

flutter_additional_ios_build_settings(target) 줄을 podfile에 추가해준다

post_install do |installer|
	installer.pods_project.targets.each do |target|
	flutter_additional_ios_build_settings(target)
		target.build_configurations.each do |config|
            	config.build_settings['ENABLE_BITCODE'] = 'NO'
		end
	end
end

2. metal_delegate.h not found

Podfile에 TensorFlowLiteC 2.2.0 로 직접 변경

3. vector.h not found

xcode build setting -> compile source as objective c++

4. arm64 linking object fail


...building for iOS Simulator, but linking in object file built for iOS, file
...for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

xcode build setting-> excluded architechture -> arm64 추가
