Installing Tesseract-OCR on CentOS 6

Question

I'm trying to install Tesseract-OCR on my server however when I install all what I believe to be the correct repos. When I try to install it the package is not found

I tried adding rpmforge but to no avail. Any ideas from somebody that has done before or is familiar with adding and searching through repos?

Answer 1

I have written a bash script to install Tesseract 3.05 on Centos 7. This fetches and installs all dependencies, and also installs language files for English, Hindi, Bengali and Thai.

Code available on GitHub

Hope this helps.

Answer 2

I used these instructions which worked correctly in Centos

Install Tesseract OCR libs from sources in Centos

Download Leptonica and Teseract sources:

$ wget http://www.leptonica.org/source/leptonica-1.69.tar.gz
$ wget https://tesseract-ocr.googlecode.com/files/tesseract-ocr-3.02.02.tar.gz

Configure, compile, install libs:

 $ tar xzvf leptonica-1.69.tar.gz      
 $ cd leptonica-1.69      
 $ ./configure
 $ make
 $ sudo make install

 $ tar xzf tesseract-ocr-3.02.02.tar.gz
 $ cd tesseract-3.01
 $ ./autogen.sh
 $ ./configure
 $ make
 $ sudo make install
 $ sudo ldconfig

Download languages (english) and copy to tessdata folder:

$ wget http://tesseract-ocr.googlecode.com/files/tesseract-ocr-3.02.eng.tar.gz       
$ tar xzf tesseract-ocr-3.02.eng.tar.gz       
$ sudo cp tesseract-ocr/tessdata/* /usr/local/share/tessdata

and enjoy it ;)

Answer 3

I recommend to try installing from rpm here: http://pkgs.org/download/tesseract There are also several dependencies: libpng-devel, libjpeg-devel, libtiff-devel, zlib and leptonica. Last 2 can also be found on RPM site
