1. Installing tesseract 4.0 with training.

Make a folder called Tesseract4 where you will install everything. Get in there. Follow the instructions on https://github.com/tesseract-ocr/tesseract/wiki/Compiling#linux until you reach the leptonica step.

For leptonica:

In the folder Tesseract4, git clone the following:

git clone https://github.com/danbloomberg/leptonica

Then go to the leptonica documentation, according to your OS. Follow step 2:Using autoconf. Run ./configure in this directory to build Makefiles here and in src. Autoconf handles the following automatically:

./autobuild and then ./configure


After this step, follow the instructions with sudo, making sure you are in the Tesseract4 folder. The executable tesseract should now be located in /usr/local/bin.


2. Building the training tools:

https://github.com/tesseract-ocr/tesseract/wiki/Training-Tesseract#building-the-training-tools (only make training, sudo make...)

they are in /usr/local/bin/ (check if you have the files there)

3. TrainingTesseract 4.00

Create a folder for the training. https://github.com/tesseract-ocr/tesseract/wiki/TrainingTesseract-4.00#before-you-start

Download the language files you will use from here in the tessdata folder.
