Building training tools from source

[Peter Hamberg]

Hi,

I'm trying to learn how to use tesseract, but I need some help, I think. I'm currently stuck on the training tesseract part, because for some reason I cant make the training tools.

I'm on a Ubuntu 14.04 machine, and I've followed the instructions on https://code.google.com/p/tesseract-ocr/wiki/Compiling - added the libraries, leptonica, 

wget https://tesseract-ocr.googlecode.com/files/tesseract-ocr-3.02.02.tar.gz

config, make, make install, all that seems to work without any error messages.

But when I try

make training

all i get is the message "make: Nothing to be done for `training'."

Am I in the wrong folder? What have I missed here?

Although your problem seems different...

and there is written: "If you want the training tools (3.03)..."

It means that that instruction are valid for 3.03 version and you are compiling 3.02.02 version (where training tools are built automatically).

I knew it had to be something obvious. I didn't realise that the version of the source code available from the download page wasnt the latest version. Thanks for the clarification. Switching to the newer version worked.

Re: [tesseract-dev] Re: Training tools linking failure, icu_48::* 

Here's a way to compile Tesseract on Ubuntu, while still 
using the packaging system. It will get you the training tools. 

 

sudo apt-get build-dep tesseract-ocr 
sudo apt-get install devscripts 
dget http://http.debian.net/debian/pool/main/t/tesseract/tesseract_3.03.03-1.dsc 
tar xvzf tesseract_3.03.03.orig.tar.gz 
cd tesseract-3.03 
zcat ../tesseract_3.03.03-1.diff.gz | patch -p1 
debuild -us -uc 
cd .. 
sudo dpkg -i *.deb

Hi, when I do "make training" the following error showing that is a bug in the code comes up.

It looks like you ignored configure warnings...

Zdenko's right. To help you out more, you seem to have skipped over
this part of the instructions in the Compiling wiki page:

sudo apt-get install libicu-dev # (if you plan to make the training tools)

1. if you are using debian tool you should try to use debian focused forum or raise issue at debian ;-) (it looks like do not have problem with tesseract, you have problem to build package from source)
   
2. As far as see meesage is clear:

1. 
   dpkg-checkbuilddeps: Unmet build dependencies: libleptonica-dev (>= 1.70~)
   dpkg-buildpackage: warning: Build dependencies/conflicts unsatisfied; aborting.

2. Follow project instruction[1]

Under which circumstances you will  need training tools, when you say "if you plan to use training tools"?.
