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：
