As per my knowledge i provided all the information needed if something is missing please let me know.
i'm new to homebrew but used linux OS's for sometime

and also is there a way i can install from Github or any repository directly on homebrew, like if some changes are made in git repository files i want to install them directly otherwise need to wait for realese of tar.gz or .dmg files

Answer 1

Include address should be: /opt/homebrew/Cellar/leptonica/1.82.0/include instead of /opt/homebrew/Cellar/leptonica/1.82.0/include/leptonica. If you can add the first path to your PATH variable it might work.

I had the same issue when I was running C++ code, I included the right path and the program found leptonics/allheader.h file.

Answer 2

First brew install tesseract. Then pip install tesserocr. Apparently the pip install depends on things from the brew install.

On pip 23.1.1, Python 3.10.11. Also I'm on an older MacBook, not an M1, but I got the same error as the OP.

Answer 3

I found a fix here, its for golang but might work for python too. https://github.com/otiai10/gosseract/issues/234

Install with brew install tesseract

export LIBRARY_PATH="/opt/homebrew/lib"

export CPATH="/opt/homebrew/include"

Answer 4

It's not possible to install tesserocr from pip. Indeed the build status is noted as failing as you can see on the PyPI link here.

So to install it, you need to conda install it with the following line :

conda install -c conda-forge tesserocr

Moreover you need to install tesseract with Homebrew as following :

brew install tesseract

Now if you try to run your script maybe you will have new error(s) indicating that some dylib are not found.

In order to solve this new problem(s) you need to create symbolic links (i.e. symlinks). In my case I needed to create those ones :

N.B: Before doing the following lines, check if you have a folder named lib in /usr/local, if no then create it

ln -s /opt/homebrew/Cellar/libarchive/3.6.2_1/lib/libarchive.13.dylib /usr/local/lib/libarchive.19.dylib
ln -s /opt/homebrew/Cellar/leptonica/1.82.0_1/lib/liblept.5.dylib /usr/local/lib
ln -s /opt/homebrew/Cellar/tesseract/5.3.0_1/lib/libtesseract.5.dylib /usr/local/lib
ln -s /opt/homebrew/Cellar/libtiff/4.4.0_1/lib/libtiff.5.dylib /usr/local/lib

Normally now you could be able to run your script.
