Can't run Tessarct5 MBS example

Targets macOS

Trying to run this example after downloading Home Brew and installing tesseract. It’s erroring out when looking for the leptonica library. I don’t see any Cellar folder in the /usr/local. Where might it be installed?

dlopen(/usr/local/Cellar/leptonica/1.82.0/lib/liblept.5.dylib, 0x0002): tried: ‘/usr/local/Cellar/leptonica/1.82.0/lib/liblept.5.dylib’ (no such file), ‘/System/Volumes/Preboot/Cryptexes/OS/usr/local/Cellar/leptonica/1.82.0/lib/liblept.5.dylib’ (no such file), ‘/usr/local/Cellar/leptonica/1.82.0/lib/liblept.5.dylib’ (no such file

I tried to reinstall just in case and get
Warning: tesseract 5.5.0_1 is already installed and up-to-date.

To reinstall 5.5.0_1, run:

brew reinstall tesseract

Mac-mini:~ sharond214$ brew install leptonica

Use Find Any File from Thomas Tempelmann use search for the dylib location.

Perfect I found the files and edited the xojo example to have the correct path but now I’m getting more errors.
dlopen(/opt/homebrew/Cellar/leptonica/1.85.0/lib/libleptonica.dylib, 0x0002): tried: ‘/opt/homebrew/Cellar/leptonica/1.85.0/lib/libleptonica.dylib’ (mach-o file, but is an incompatible architecture (have ‘arm64’, need ‘x86_64’)),

Did homebrew install the wrong version? First time using homebrew.

Thanks

Could you set the project to build as universal?

Can I use this on an ios app. If so how to install tesseract to use there?

Well, you would need a compiled version of the tesseract library for iOS as e.g. framework and then tell our plugin to load it.

Or you check out the VNRecognizeTextRequestMBS class, which runs on iOS directly without tesseract.
