使用CMake实用程序构建Azure物联网网关SDK解决方案

Question

我正在尝试使用适用于Windows 10平台上的Visual Studio 2015的CMake 3.71实用程序构建示例Azure IoT Gateway SDK项目。当我尝试分别在VS2015命令行和CMake GUI中构建项目时，我收到以下错误日志：

Determining if the _M_AMD64 exist failed with the following output:

有人可以告诉我我做错了什么或指导我吗？我花了很多时间试图弄清楚如何解决这个问题。我在网上广泛搜索了解决方案，但没有成功。

提前致谢

似乎与此note：

有关

  

注意：确保将repo克隆到目录heirachy with less   超过20个字符（如果路径是前缀\ azure-iot-gateway-sdk，   前缀必须少于20个字符）。 Windows有局限性   文件名的长度并将repo放在更深层次的层次结构中   超过20个字符将导致构建失败。我们的build.cmd脚本   如果最终会遇到此失败，则会抛出错误，但可以   在使用cmake手动构建项目时点击此项。

我杀了目录中的“项目”（... Documents / GitHub / project / azure-iot-gateway-sdk / ...），然后就可以了。

因此，您需要缩短将repo克隆到的目录的长度。
