tesseract的編譯安裝 tesseract編譯錯誤：fatal error: allheaders.h: No such file or directory
需要安裝：
<span style="font-family:'Microsoft YaHei';font-size:14px;">
apt-get install autoconf
apt-get install automake
apt-get install libtool
</span>
-------------------------------------------------------------------------------------------------------------------------------------
安裝過程，參考以下：
安裝依賴包
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)
--------------------------------------------------------------------------
安裝leptonica
tesseract依賴於leptonica,所以首先要下載安裝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
安裝完成之後，配置環境變數,
gedit /etc/bash.bashrc
在檔案末尾，新增環境變數的配置
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=$LIBRARY_PATH:/usr/local/leptonica/lib
export LIBRARY_PATH
source /etc/bash.bashrc
gedit /etc/ld.so.conf
在檔案末尾，新增
/usr/local/leptonica/lib
source /etc/ld.so.conf
----------------------------------------------------------------------------------------------------------------------------
下載tesseract.
第一步：unzip tesseract
第二步：cd tesseract
第三步：./autogen.sh 如果不報錯
第四步：LIBLEPT_HEADERSDIR=/usr/local/leptonica/include/leptonica ./configure --prefix=/usr/local/tesseract --with-extra-libraries=/usr/local/leptonica/lib 【注意：tesseract依賴於leptonica】
第五步：make
第六步：make install
第七步：make training
第八步: sudo make training-install 【注意：是training-install,不是 training install】
安裝完後
新增環境變數PATH,否則，需要每次到安裝路徑執行。
第九步：gedit /etc/bash.bashrc,末尾新增
PATH=$PATH:/usr/local/tesseract/bin
export PATH
第十步：source /etc/bash.bashrc
------------------------------------------------------------------------------------------------------------------------------------------------------
然後，開啟終端

tesseract編譯錯誤：fatal error: allheaders.h: No such file or directory
錯誤描述：
globaloc.cpp:25:33: fatal error: allheaders.h: No such file or directory #include "allheaders.h"
解決辦法：
1、確認是否安裝了leptonica
2、配置環境變數
vi /etc/profile 新增： 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
如果仍然無法解決，參考以下文章重新安裝：
