Install Tesseract 4.0-Ubuntu
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 (next to tesseract for example) https://github.com/tesseract-ocr/tesseract/wiki/TrainingTesseract-4.00#before-you-start
