macos metal: #include "leptonica/allheaders.h" about tesserocr HOT 12 CLOSED

Did you install leptonica?

from tesserocr.

Yes, Leptonica is installed, as described here: https://macappstore.org/leptonica/

from tesserocr.

Can you please modify #include "leptonica/allheaders.h" to #include "allheaders.h"?

from tesserocr.

where do I need to make this change? Where does tesserocr.cpp come from?

from tesserocr.

tesserocr.cpp line 796 - it is in error message

from tesserocr.

Where do i find tesserocrp.cpp? It's not in the github repo and I don't think it's on my machine before I pip install tesserocr.

from tesserocr.

tesserocr.cpp is generated file by setup.py ;-)

So can you please provide a full log of the following commands?

git clone https://github.com/sirfz/tesserocr.git
cd tesserocr
python3 setup.py build

Any suggestions what we can do about this?

from tesserocr.

First of all: I am not mac user ;-)

Can you run and provide output of pkg-config --libs --cflags lept ?

Generally you need to specify path where compiler (clang) can find leptonica header file. So first of all please find there is located "allheaders.h" file.

Then you will need something like this (I found it on internet, so I hope it is correct):

export CPLUS_INCLUDE_PATH="${CPLUS_INCLUDE_PATH:+${CPLUS_INCLUDE_PATH}:}<path_to_leptonica>"

• you can try this:

brew install tesseract
export LIBRARY_PATH="/opt/homebrew/lib"
export CPATH="/opt/homebrew/include"

After this setting try to install tesserocr (python setup.py build).

from tesserocr.

export LIBRARY_PATH="CPPFLAGS=-I/opt/homebrew/Cellar/leptonica/1.82.0_1/include/leptonica"

worked. thanks

from tesserocr.

For me, doing the 2nd part of @zdenop 's solution worked
export LIBRARY_PATH="/opt/homebrew/lib"
export CPATH="/opt/homebrew/include"
