如何解决?

推荐答案

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 子模块链接到适当的 Leptonica 和 tesseract_3.05 源.

Since the time of the linked answer, project structure was changed. It's updated to Tesseract 3.05 and clear Git submodule links to the proper Leptonica and tesseract_3.05 sources added.

您似乎已经为他们下载了主源.目前 VS2015_Tesseract 与其不兼容.

It looks like you've downloaded master sources for both of them. At the moment VS2015_Tesseract is not compatible with it.

正确的依赖链接是:leptonica @ e98a794tesseract_3.05 @ 7fe95f0.下载并尝试重建解决方案.

Proper dependency links are: leptonica @ e98a794 and tesseract_3.05 @ 7fe95f0. Download it and try to rebuild the solution.
