yum install gcc gcc-c++ yum install autoconf automake libtool yum install libjpeg-devel libpng-devel libtiff-devel zlib-devel
tar -xzvf leptonica-1.74.4.tar.gz
cd leptonica-1.74.4 ./configure make && make install
export LD_LIBRARY_PATH=$LD_LIBRARY_PAYT:/usr/local/lib export LIBLEPT_HEADERSDIR=/usr/local/include export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
cd tesseract-3.04.00 ./autogen.sh autoreconf -i ./configure --with-extra-includes=/usr/local/include --with-extra-libraries=/usr/local/include
这时会提示： Configuration is done. You can now build and install tesseract by running:
$ make $ make install
Training tools can be built and installed with:
$ make training $ sudo make training-install
继续编译，先编译tesseract，在编译安装 training make sudo make install make training make training-install
sudo ldconfig
用法 tesseract 1.jpg output -l chi_sim tesseract 1.jpg stdout
