centos下安装tessrect-ocr及训练工具问题分析及解决办法

最近要在服务器上搭建tessrect-ocr和训练工具，搭建一个训练网页：

http://115.159.205.168/ocr_php/public/index.php

在搭建中遇到了以下问题：

1.找不到tessrect-ocr安装包

2.训练工具无法安装

1.解决办法：

[cpp]view plaincopy

sudoyuminstalltesseract.i686

2.安装centos库时，没有安装训练工具，所以要进行源码安装：

1.下载源码：

[cpp]view plaincopy

wgethttps://github.com/tesseract-ocr/tesseract/archive/master.zip

2.解压：

unzip tesseract-master.zip

3.运行以下命令：

[cpp]view plaincopy

./autogen.sh

./configure

make

sudomakeinstall

sudoldconfig

现在已经安装好引擎了，现在安装训练工具：

[cpp]view plaincopy

maketraining

sudomaketraining-install

但是如果你的程序在./configure时显示这个：

[cpp]view plaincopy

Configurationisdone.

Youcannowbuildandinstalltesseractbyrunning:

$make

$sudomakeinstall

Youcannotbuildtrainingtoolsbecauseofmissingdependency.

Checkconfigureoutputfordetails.

那训练工具肯定安装不成功，因为它没有生产Makefile文件

[cpp]view plaincopy

configure:creating./config.status

config.status:creatingMakefile

config.status:creatingtesseract.pc

config.status:creatingapi/Makefile

config.status:creatingccmain/Makefile

config.status:creatingopencl/Makefile

config.status:creatingccstruct/Makefile

config.status:creatingccutil/Makefile

config.status:creatingclassify/Makefile

config.status:creatingcube/Makefile

config.status:creatingcutil/Makefile

config.status:creatingdict/Makefile

config.status:creatingneural_networks/runtime/Makefile

config.status:creatingtextord/Makefile

config.status:creatingviewer/Makefile

config.status:creatingwordrec/Makefile

config.status:creatingtessdata/Makefile

config.status:creatingtessdata/configs/Makefile

config.status:creatingtessdata/tessconfigs/Makefile

config.status:creatingtesting/Makefile

config.status:creatingjava/Makefile

config.status:creatingjava/com/Makefile

config.status:creatingjava/com/google/Makefile

config.status:creatingjava/com/google/scrollview/Makefile

config.status:creatingjava/com/google/scrollview/events/Makefile

config.status:creatingjava/com/google/scrollview/ui/Makefile

config.status:creatingdoc/Makefile

config.status:creatingconfig_auto.h

config.status:config_auto.hisunchanged

config.status:executingdepfilescommands

config.status:executinglibtoolcommands

很明显，没有产生training的Makefile文件

下面解决办法：

1.去看./configure产生的信息：

[cpp]view plaincopy

checkinglimits.husability...yes

checkinglimits.hpresence...yes

checkingforlimits.h...yes

checkingmalloc.husability...yes

checkingmalloc.hpresence...yes

checkingformalloc.h...yes

checkingforstdbool.hthatconformstoC99...yes

checkingfor_Bool...no

checkingforcairo...yes

如果有Warning：...............can't install training tools 按照其提示未安装的进行按照:

如果找不到包,执行以下命令:

[cpp]view plaincopy

yumlist|gerpname

找到对应包。

这里有一个包ICU版本比较旧，要进行源码安装：

1.下载源码：

[cpp]view plaincopy

wgethttp://download.icu-project.org/files/icu4c/58.1/icu4c-58_1-src.tgz

2. 安装

[cpp]view plaincopy

./configure

make

sudomakeinstall

然后重新运行./configure

如果没有Warning但仍然显示无法安装：

修改config.status文件，325行添加 training/Makefile

然后进入training目录，

执行

[cpp]view plaincopy

make

makeinstall
