Question

我使用了here提供的解决方案，以便在我的windows10 x64项目，Visual Studio 2017上使Tesseract 3.05正常工作。构建它时我遇到了这些错误：

如何解决它们？

Answer 1

自链接答案的时间以来，项目结构已更改。它更新为Tesseract 3.05并清除Git子模块链接到添加的正确Leptonica和tesseract_3.05来源。

看起来您已经下载了两者的主要来源。目前VS2015_Tesseract与它不兼容。

正确的依赖关系链接是：leptonica @ e98a794和tesseract_3.05 @ 7fe95f0。下载并尝试重建解决方案。

Answer 2

添加 C / C ++ - ＆gt;其他包含库：

C:\Users\Jihed Mestiri\Documents\VS2015_Tesseract-master\liblept
C:\Documents\VS2015_Tesseract-master\leptonica\src
C:\Users\Documents\VS2015_Tesseract-master\tesseract_3.05\wordrec
C:\Users\Documents\VS2015_Tesseract-master\tesseract_3.05\opencl
C:\Users\Documents\VS2015_Tesseract-master\tesseract_3.05\viewer
C:\Users\Documents\VS2015_Tesseract-master\tesseract_3.05\textord
C:\Users\Documents\VS2015_Tesseract-master\tesseract_3.05\neural_networks\runtime
C:\Users\Documents\VS2015_Tesseract-master\tesseract_3.05\dict
C:\Users\Documents\VS2015_Tesseract-master\tesseract_3.05\cutil
C:\Users\Documents\VS2015_Tesseract-master\tesseract_3.05\cube
C:\Users\Documents\VS2015_Tesseract-master\tesseract_3.05\classify
C:\Users\Documents\VS2015_Tesseract-master\tesseract_3.05\ccstruct
C:\Users\Documents\VS2015_Tesseract-master\tesseract_3.05\ccutil
C:\Users\Documents\VS2015_Tesseract-master\tesseract_3.05\ccmain
C:\Users\Documents\VS2015_Tesseract-master\tesseract_3.05\api
C:\Users\Documents\VS2015_Tesseract-master\tesseract_3.05\vs2010\port

以及链接器中包含.lib文件的目录 - ＆gt;一般 - ＆gt;其他图书馆馆长，并包含在链接器 - ＆gt;输入 - ＆gt;其他依赖项Tesseract和Leptonica的这些.lib文件：

libtesseract.lib
giflib.lib
libjpeg.lib
liblept.lib
libpng.l‌ib
libtiff.lib
li‌bwe‌bp.lib
openjpeg.lib
‌zlib.lib

我的test program的编译错误已更改为：

1>------ Build started: Project: RedEyeRemover, Configuration: Debug x64 ------
1>LINK : fatal error LNK1104: cannot open file 'libpng.l‌ib'
1>Done building project "RedEyeRemover.vcxproj" -- FAILED.
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

包含libpng.lib文件的目录包含在 Linker-＆gt; General 中。

参数来自我从VS2015_Tesseract

构建的 tesseract / tesseract.vcxproj

错误背后的原因是什么？有没有办法验证tesseract.vcxproj自己正常工作？因为我在x64目标上在Visual Studio 2017（使用v140 = VS 2015版本的版本）上编译它时会出现错误。

编辑：解决方案：我发现问题出在链接器 - ＆gt;一般 - ＆gt;其他库目录我在路径的父目录之一中有一个空格，例如：“xxx xxx / tesseract”。 =＆GT;避免使用带空格的路径。
