首先在机器上找个目录打开官方git https://github.com/tesseract-ocr

我们在服务器上找个目录 git clone https://github.com/tesseract-ocr/tesseract.git

如果新机器就随手安装上工具包

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

安装leptonica1.7（4.0必须在1.74以上）

wget http://www.leptonica.org/source/leptonica-1.80.0.tar.gz

tar -xzvf leptonica-1.80.0.tar.gz
cd leptonica-1.80.0
./configure --prefix=/usr/local/
make && make install

配置环境
vim \etc\bashrc
加入

PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig
export PKG_CONFIG_PATH
CPLUS_INCLUDE_PATH=$CPLUS_INCLUDE_PATH:/usr/local/include/
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/lib
export LD_LIBRARY_PATH
LIBRARY_PATH=$LIBRARY_PATH:/usr/local/lib
export LIBRARY_PATH
TESSDATA_PREFIX=/root/tesseract/
export TESSDATA_PREFIX

最后刷新

source /etc/bashrc

回到tesseract目录，开始安装

./autogen.sh

./configure --with-extra-includes=/usr/local/include --with-extra-libraries=/usr/local/include

注：这时有可能会报 configure: error: Leptonica 1.74 or higher is required. Try to install libleptonica-dev package.

明明我们已经安装了的。为什么还会报呢？

那就要加入环境变量

vim /etc/profile

在最后插入

export LD_LIBRARY_PATH=$LD_LIBRARY_PAYT:/usr/local/lib
export LIBLEPT_HEADERSDIR=/usr/local/include
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig

最后刷新下文件

source /etc/profile

然后我们再执行

./autogen.sh
./configure

这时就没有 leptonica问题啦，随后make下

make && sudo make install

最后我们用代码测试一切都正常，但到项目中却莫明奇妙地失败，断点服务直接崩掉，cache不住，找不到报错

各种百度google最后确认下来可能少了tess4j要的linux依赖库

执行下

cp /usr/local/lib/*.so.* /usr/lib64/

如果报

Error in findTiffCompression: function not present
Error in pixReadStreamTiff: function not present
Error in pixReadStream: tiff: no pix returned
Error in pixRead: pix not read
Unsupported image type.

tesseract编译错误：fatal error: allheaders.h: No such file or directory

错误描述：

globaloc.cpp:25:33: fatal error: allheaders.h: No such file or directory  

#include          "allheaders.h"

解决办法：

1、确认是否安装了leptonica

2、配置环境变量

vi /etc/profile

添加：
CPLUS_INCLUDE_PATH=$CPLUS_INCLUDE_PATH:/usr/local/leptonica/include/leptonica
export CPLUS_INCLUDE_PATH
C_INCLUDE_PATH=$C_INCLUDE_PATH:/usr/local/leptonica/include/leptonica
export C_INCLUDE_PATH
 
source /etc/profile

如果仍然无法解决，参考以下文章重新安装：
