我从libgit2存储库（提交4ae29053d5）获取/合并了最后的更改，创建了build子目录，并使用Visual Studio 2010以这种方式在Windows 7上编译了库：

一切似乎都好。启动测试时，它失败了：

这是一个知情吗？似乎很多（子）测试都通过了。我不知道测试框架。最后的消息是否意味着只有diff::workdir::submodules失败了？
答案 0 :(得分：0)
我不知道测试框架。
Libgit2依赖于 Clar 测试框架。
最后的消息是否意味着只有diff :: workdir :: submodules失败了？
是。更准确地说，它指向 failing assertion
这是一个众所周知的情况吗？
没有。 libgit2团队努力工作，总是让测试通过。
我在本地尝试过，但我无法重现这个问题。此 gist 包含针对 libgit2@4ae29053 的构建和测试运行。
这也是针对Visual Studio 2010在Win 7（32位）平台上运行的。
我看到的唯一区别是你运行的是旧版本的Python，但这应该不是问题。 Clar 依靠Python来生成测试套件（在项目的 README 文件中有关此内容的更多信息）并支持Python返回版本2.5。
如果您可以成功重现此故障，请在 libgit2 issue tracker 中打开一个问题，因为这可能需要更深入的故障排除，这可能不适合StackOverflow格式。
