Re: [tesseract-ocr] Training tools don't get built when building tesseract from souce

[Shree Devi Kumar]

sudo apt-get remove tesseract-ocr
sudo apt-get remove libtesseract-dev

sudo add-apt-repository ppa:alex-p/tesseract-ocr
sudo apt-get update

sudo apt install tesseract-ocr
sudo apt install libtesseract-dev  

The above will  unintsall and then install the latest version binaries from ppa. 

Why are you then again building from source?

ppa installs the training scripts and puts them in the path too.

Hi,

• I was working with a previous version of Tesseract and I was asked to get the latest snapshot when I came across the below error,

• I followed the wiki and below video tutorials to build Tesseract from source,

• I didn't build Leptonica as I had already built and installed 1.74.4 version,

• I followed exactly below commands. I have attached the output of some of them,

• My OS details are as below,

Linux shandigutt-laptop-ubuntu 4.4.0-130-generic #156-Ubuntu SMP Thu Jun 14 08:53:28 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

After building Tesseract following above steps, when I queried Tesseract version I get the below output,

tesseract -v
tesseract 4.0.0-beta.4-26-gfd49
 leptonica-1.74.4
  libjpeg 8d (libjpeg-turbo 1.4.2) : libpng 1.2.54 : libtiff 4.0.6 : zlib 1.2.8

 Found SSE

• Files tree in tesseract directory after building is attached as tesseract_tree.txt
  

I can't find all the training scripts I had previously. Appreciate your help on this.

Thanks,

Thanks a lot Shree,

it's already installed.
