How to integrate the OCR Tesseract library into a C ++ program

I am trying to use the Tesseract OCR Library to create a program for reading photos of elevator floor numbers. I did not find an example of how to include the Tesseract library in a C ++ file. Sort of:

#include "tesseract.h"

I am using Tesseract v 3.00 on Ubuntu 10.10.

PlatformStatus The page has a few comments on how to install it. It has dependencies (leptonica), which also need to be installed.

Another solution , also related to the discussion above, has similar information for other Linux distributions.

When it comes to linking to your program, this post has some features

There is also a C shell for basic API calls ; looking at the attached files, tell what to include. Other wrappers are available here.

The API base class documentation is here ...

The Installation Platform Status page opens.

 sudo apt-get install libleptonica-dev autoconf automake libtool libpng12-dev libjpeg62- dev libtiff4-dev zlib1g-dev subversion g++ cd svn checkout http://tesseract-ocr.googlecode.com/svn/trunk/ tesseract-ocr cd tesseract-ocr ./autogen.sh ./configure make sudo make install sudo ldconfig cd /usr/local/share/tessdata/ sudo wget http://tesseract-ocr.googlecode.com/files/eng.traineddata.gz sudo gunzip eng.traineddata.gz cd ~/tesseract-ocr/ tesseract phototest.tif phototest cat phototest.txt
