tesseract的编译安装

 

须要安装：

apt-get install autoconf
apt-get install automake
apt-get install libtool

-------------------------------------------------------------------------------------------------------------------------------------

安装过程，參考下面：

安装依赖包

sudo apt-get install autoconf automake libtool
sudo apt-get install libpng12-dev
sudo apt-get install libjpeg62-dev
sudo apt-get install libtiff4-dev
sudo apt-get install zlib1g-dev
sudo apt-get install libicu-dev      # (if you plan to make the training tools)
sudo apt-get install libpango1.0-dev # (if you plan to make the training tools)
sudo apt-get install libcairo2-dev   # (if you plan to make the training tools)

--------------------------------------------------------------------------

安装leptonica

tesseract依赖于leptonica,所以首先要下载安装leptonica

第一步:tar zxvf leptonica-1.73.tar.gz

第二步:cd leptonica-1.73

第三步:./configure --prefix=/usr/local/leptonica

第四步：make

第五步：make install

安装完毕之后，配置环境变量,

gedit /etc/bash.bashrc

在文件末尾，加入环境变量的配置

PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/leptonica/lib/pkgconfig
export PKG_CONFIG_PATH
CPLUS_INCLUDE_PATH=$CPLUS_INCLUDE_PATH:/usr/local/leptonica/
export CPLUS_INCLUDE_PATH
C_INCLUDE_PATH=$C_INCLUDE_PATH:/usr/local/leptonica/include/leptonica
export C_INCLUDE_PATH
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/leptonica/lib
export LD_LIBRARY_PATH
LIBRARY_PATH=$LIBRARY_PATH:/usr/local/leptonica/lib
export LIBRARY_PATH

source /etc/bash.bashrc

gedit /etc/ld.so.conf

在文件末尾。加入

/usr/local/leptonica/lib

source /etc/ld.so.conf

----------------------------------------------------------------------------------------------------------------------------

下载tesseract.

第一步：unzip tesseract

第二步：cd tesseract

第三步：./autogen.sh   假设不报错

第四步：LIBLEPT_HEADERSDIR=/usr/local/leptonica/include/leptonica ./configure --prefix=/usr/local/tesseract --with-extra-libraries=/usr/local/leptonica/lib   【注意：tesseract依赖于leptonica】

第五步：make

第六步：make install

第七步：make training

第八步: sudo make training-install  【注意：是training-install,不是 training install】

安装完后

加入环境变量PATH,否则，须要每次到安装路径执行。

第九步：gedit /etc/bash.bashrc,末尾加入

PATH=$PATH:/usr/local/tesseract/bin

export PATH

第十步：source /etc/bash.bashrc

------------------------------------------------------------------------------------------------------------------------------------------------------

然后，打开终端
