Install Tesseract-OCR on CentOS 6

Question

I try to install Tesseract-OCR on my server, however, when I install everything that in my opinion is the correct repo. When I try to install it, the package was not found.

I tried adding rpmforge, but to no avail. Any ideas from someone who has done this before or are familiar with adding and searching through repositories?

Answer 1

I used these instructions that worked correctly in Centos

Install Tesseract OCR libs from sources in Centos

Download the Leptonic 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 libraries:

  $ 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 the languages ​​(English) and copy to the 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 2

I recommend trying installing with rpm here: http://pkgs.org/download/tesseract There are also several dependencies: libpng-devel, libjpeg-devel, libtiff-devel, zlib and leptonica. The last 2 can also be found on the RPM website

Answer 3

This worked for me:

 /usr/bin/yum --enablerepo epel-testing install tesseract.x86_64 tesseract-langpack-fra.noarch 

tesseract is not in the epel repository, but in epel-testing repo witch is not activated by default.

Answer 4

I wrote a bash script to install Tesseract 3.05 on Centos 7. This allows you to install and install all the dependencies, and also installs language files for English, Hindi, Bengali and Thai.

Code is available on GitHub.

Hope this helps.

Download the languages ​​(English) and copy to the tessdata folder:
