Question

所以我一直在尝试在Windows上构建libevent。但是，当我运行nmake MakeFile.nmake ...

时，它一直为我提供以下输出

似乎无法找到某些文件。因此，我找到了winsock2.h和其他文件所在的目录，并向这些文件添加了环境变量，但是仍然出现相同的错误。我还注意到，在我的系统上实际上找不到sys / types.h和limits.h。如果有人可以帮助您找出导致此问题的原因，我将不胜感激。谢谢。

更新：因此，我确定了系统上所有所需文件的位置，并尝试将环境变量添加到适当的目录中，但是，在运行nmake时仍然找不到它们。

libevent README.md文件不建议使用nmake。它指向您使用CMake和现有的Makefile.nmake在顶部有一个很大的注释，表明它可能不起作用。因此，请安装cmake（您可以使用Chocolatey'choco install cmake'），然后按文档所述运行命令。

这对我使用Visual Studio 2017和分支release-2.1.8-stable的git checkout一起工作。我添加了disable-openssl选项，因为它没有此选项就失败了，我不想花时间单独安装它。

无法在Windows上构建libevent
