Step 1: Installing the basic CentOS Dependencies

# yum install autoconf automake libtool pkgconfig.x86_64 libpng12-devel.x86_64 libjpeg-devel libtiff-devel.x86_64 zlib-devel.x86_64

Step 2: Compile Leptonica-1.79

• Compiling Leptonica-1.79 on CentOS 7

Step 3: Compile tesseract-5.0

Load a recent version of GNU C++. In my case, I’ve used GNU-6.5 and ISL-0.18 (Integer Set Library)

a. Yum install git

$ yum install git

b. Configure lept.pc for Leptonica-1.79 if you have placed leptonica in a unique directory

$ export PKG_CONFIG_PATH=/usr/local/leptonica-1.79.0/lib/pkgconfig

c. Compile the Tesseract

$ git clone https://github.com/tesseract-ocr/tesseract.git
$ cd tesseract
$ ./autogen.sh
$ ./configure --prefix=/usr/local/tesseract-5.0 
$ make
$ make install
