opencvを0.76.1から0.91.3にしてみる。 https://github.com/twistedfall/opencv-rust

[kyakuno]

改善しなかったので、rustをupdateすると、下記のエラー。

error: failed to run custom build command for clang-sys v1.7.0

[kyakuno]

brew install llvmが必要そう。

[kyakuno]

下記と同じでopencv 0.8.0がいるみたい。 https://github.com/axinc-ai/ailia_yolox_rust/issues/1 https://github.com/twistedfall/opencv-rust/issues/462

[kyakuno]

llvmを入れても、 　error: failed to run custom build command for clang-sys v1.7.0 は改善せず。

[kyakuno]

llvmを入れて、opencv 0.80.0にすると動いた。

[kyakuno]

っと思ったら、libcでエラー。

昔ビルドできていた、ailia_yolox_rustでも同じエラーになる。

[kyakuno]

opencv v0.91.3だと下記のエラーになる。 a libclang shared library is not loaded on this thread

これは下記のPoint.8である。 https://github.com/twistedfall/opencv-rust/blob/master/TROUBLESHOOTING.md

opencvのdependenciesのfeaturesにclang-runtimeを入れろと書いている。 opencv = {version = "*", features = [ "clang-runtime"]} https://qiita.com/higumachan725/items/25198370ce6b8603356e

[kyakuno]

opencvをv0.91.3にアップデートして、clang-runtimeを入れたらailia-sysはビルドできた。

[kyakuno]

アプリもビルドできた。
