c++ - Visual Studio 2017 中的 Tesseract 3.05 构建错误

Question

为了让 Tesseract 3.05 在我的 windows10 x64 项目 visual studio 2017 上运行，我使用了 here 提供的解决方案。我在构建它时遇到了这些错误:

如何解决？

Answer 1

自链接答案发布以来，项目结构发生了变化。它已更新到 Tesseract 3.05 并清除 Git 子模块链接到添加的正确 Leptonica 和 tesseract_3.05 源。

看起来您已经下载了它们的主要源代码。此刻VS2015_Tesseract与它不兼容。

正确的依赖链接是:leptonica @ e98a794和 tesseract_3.05 @ 7fe95f0 .下载它并尝试重建解决方案。
