[tesseract-ocr] Re: Install Tesseract 4 on CentOS and Red Hat [SOLVED!]
Hello Vinsec! Sorry for the slow reply. Work is keeping me busy. No mystery there. For me, I have been put on another project, so I haven't been using Tesseract for awhile. I hope somebody more experienced like Shree or Александр Поздняков can give you the right answer. Good luck!

Re: [tesseract-ocr] Re: Install Tesseract 4 on CentOS and Red Hat [SOLVED!]
Hello Periasamy! Do you know what version of CentOS you're using? I used CentOS 7, and I haven't tried this installation script on other versions of CentOS. I never got the libtool error, so I'm sorry that I don't know what the exact solution is. If you are using CentOS 7, perhaps there have been updates to packages (like libtool) that make installation a little trickier. Good luck! If you discover the solution, feel free to post it here.

[tesseract-ocr] Re: Install Tesseract 4 on CentOS and Red Hat [SOLVED!]
Hello Александр! I took a look at your stuff; it is very extensive. If all the installations work, this should be front-paged! I have never used openSUSE. Could you point me to some resources to figure out how use your installation packages? @shree Thanks for the info. I definitely notice that Tesseract 4 is more accurate--more example, Tesseract 4 can read small italics font whereas Tesseract 3 makes lots of mistakes. Seems like Tesseract 4 is the future! -- You received this message because you are subscribed to the Google Groups "tesseract-ocr" group.

Re: [tesseract-ocr] Install Tesseract 4 on CentOS and Red Hat [SOLVED!]
@Shree Thanks for the tip. Just 2 quick questions. 1) From https://github.com/tesseract-ocr/tesseract/wiki/Data-Files, it says that "osd" and "equ" traineddata files are compatible between Tesseract 3 and 4. In the GitHub tessdata_fast repo (https://github.com/tesseract-ocr/tessdata_fast), "osd" is there with the commit "Use legacy Orientation Script Detector (OSD) because that is the only thing that currently works." However, "equ" is not in the repo. Was this simply a small mistake where the maintainer forgot to include the "equ" data file? 2) Also, with tessdata_fast, I was able to get Tesseract 4 running faster than using Tesseract 4 with tessdata. However, is Tesseract 4 supposed to be slower than Tesseract 3 because that's what I'm experiencing? # Here are the updated instructions to download tessdata_fast, which I tested to indeed perform faster than tessdata. # However, when calling Tesseract from the command line, using the arguments "--oem 2" will no longer work. # Use "--oem 1" since only the neural net LSTM model exists if using tessdata_fast. wget https://github.com/tesseract-ocr/tessdata_fast/blob/master/osd.traineddata?raw=true wget https://github.com/tesseract-ocr/tessdata_fast/blob/master/eng.traineddata?raw=true wget https://github.com/tesseract-ocr/tessdata_fast/blob/master/chi_sim.traineddata?raw=true -- You received this message because you are subscribed to the Google Groups "tesseract-ocr" group.

[tesseract-ocr] Install Tesseract 4 on CentOS and Red Hat [SOLVED!]
Hello! Most people are probably running Tesseract 4 on Ubuntu, MacOS, and Windows. Unfortunately, there are no clear instructions on installing Tesseract 4 for other flavors of Linux--probably most notably CentOS and Red Hat. After going through dependency hell, I successfully installed Tesseract 4 onto CentOS 7. I presume that the installation script should also work for Red Hat. I want to give credit to EisenVault because this script is essentially a modified version of his script. This is my first contribution to open source software, so any tips will be highly appreciated! When running this script line by line, you probably have to prefix "sudo" to each line, or you can copy and paste into a bash script and then run sudo along with the script. I have tested both to work on a fresh image of CentOS 7 on VirtualBox.
