Window10 VS2019配置tesseract源码

1、配置tessract源码，折腾了好久[2020.5.5-2020.5.11]，今晚终于配置成功了。

成功

1、从github下克隆Tesseract-OCR_for_Windows，注意是克隆不是下载
 
    git clone https://github.com/peirick/Tesseract-OCR_for_Windows.git

2、 从github下克隆leptonica
    
    git clone https://github.com/DanBloomberg/leptonica.git

3、 从github下克隆tesseract
    
    git clone https://github.com/tesseract-ocr/tesseract.git

4、把步骤2克隆完成的leptonica文件夹里面文件拷到Tesseract-OCR_for_Windowsleptonica

5、把步骤3克隆完成的tesseract文件夹里面文件拷到Tesseract-OCR_for_Windows	esseract_3.05
    
6、tesseract.sln，编译，会有报错。

7、把
static const STRING kCharsToEx[] = {"'", "`", """, "\", ",", ".",
	"〈", "〉", "《", "》", "」", "「", ""};

修改成
    
static const STRING kCharsToEx[] = { "'", "`", """, "\", ",", ".",
	"<", ">", "<<", ">>", "" };    

8、再次编译运行，成功。
    
如果需要dll，打开项目属性，在常规->配置类型处选择动态库;C/C++预处理 -> 预处理器定义处增加TESS_EXPORTS

方法[但是不知道怎么用到vs工程里面]

sw setup
sw build org.sw.demo.google.tesseract.tesseract-master

失败

cppan --build pvt.cppan.demo.google.tesseract.tesseract-master

失败

还有其它尝试就不列出了。
