unable to "make training"

[Tairen Chen]

Hi, all,

      I want to train the tesseract to read a special font from the image, but for some reason, I can't "make training" when I follow the link " https://github.com/tesseract-ocr/tesseract/wiki/TrainingTesseract-4.00#building-the-training-tools "

      I got the following message: " Need to reconfigure project, so there are no errors " when I tried to type "make training" in the terminal. I tried to find suggestion from here or Tesseract Github Issues, the closest one is https://github.com/tesseract-ocr/tesseract/issues/2261. But there is no clear answer in the end.

      Please help me if you have some hints. Thank you in advance.

      I am using the Ubuntu 16.04 and the Tesseract version info is below: 

      tesseract 4.1.0-rc1-255-g332a1

      leptonica-1.75.3

      libjpeg 9c : libpng 1.6.36 : libtiff 4.0.6 : zlib 1.2.8

      Found AVX2

      Found AVX

      Found SSE

Hi, Zdenko,

     I mainly followed these links "https://github.com/tesseract-ocr/tesseract/wiki/Compiling-%E2%80%93-GitInstallation" and "https://github.com/tesseract-ocr/tesseract/wiki/TrainingTesseract-4.00".

     Some packages such as libjpeg, libpng, libtiff, zlib, leptonica, I downloaded and installed from source.

     I uninstall and install it again, I have the same problem even with " tesseract 5.0.0-alpha-11-g8a34"

     Please let me know if you have some hints.

     Thank you.

You can now build and install tesseract by running:

$ make

$ sudo make install

$ sudo ldconfig

Documentation will not be built because asciidoc or xsltproc is missing.

You can not build training tools because of missing dependency.

Check configure output for details.

"""

You can see from BOLD and/or Purple color fonts. I think for some reason the compiling could not find the required package to make the training tool. I double check the version of libpango in my Ubuntu: it is "libpango1.0-dev is already the newest version (1.38.1-1)", and the version of icu-uc is: "libicu-dev is already the newest version (55.1-7ubuntu0.4). ", and cario is installed as well as " libcairo2-dev is already the newest version (1.14.6-1). ". So all the packages are satisfied with the compiling requirement.

 So the next question is why the compiling could not find the packages that I have installed?

I am not familiar with the "make" file system, please give me your suggestions.

Thank you!

Hi, Zdenko,

     Thank you for your reply.

     I uninstall every package that I had installed and remove unzip the packages.

     Then, I follow the link to install again.

     Now the training is working. :-)

     

     Thank you for pointing me to the configure file and I understand what is "reconfigure" mean now. Appreciate your help.

All the best,

                            Tairen
