先安装依赖库：

Ubuntu

If they are not already installed, you need the following libraries (Ubuntu 16.04/14.04):

sudo apt-get install g++ # or clang++ (presumably)
sudo apt-get install autoconf automake libtool
sudo apt-get install pkg-config
sudo apt-get install libpng-dev
sudo apt-get install libjpeg8-dev
sudo apt-get install libtiff5-dev
sudo apt-get install zlib1g-dev

if you plan to install the training tools, you also need the following libraries:

sudo apt-get install libicu-dev
sudo apt-get install libpango1.0-dev
sudo apt-get install libcairo2-dev

下载安装Leptonica

wget http://www.leptonica.com/source/leptonica-1.74.4.tar.gz

tar xvf leptonica-1.74.tar.gz
cd leptonica-1.74
./configure
make

sudo make install

sudo ldconfig
