Question

教程链接： http://kaaproject.github.io/kaa/docs/v0.10.0/Programming-guide/Your-first-Kaa-application/

我正在采取步骤＆＃34;启动应用程序＆＃34;。我正在使用C ++ SDK。

我正在尝试在教程中创建程序，但我无法运行该程序。这些说明适用于Linux，需要我运行一些命令。由于我不能这样做，我想如果我在Visual Studio中打开它就可以了。

当我打开Visual Studio时，我发现＆＃34;开始＆＃34;按钮被替换为＆＃34;附加...＆＃34;按钮。我以前从未见过这个。

有人可以帮我弄清楚如何运行程序吗？

感谢。

Windows页面http://kaaproject.github.io/kaa/docs/v0.10.0/Programming-guide/Using-Kaa-endpoint-SDKs/C++/SDK-Windows/解释了Windows平台的C ++ SDK和应用程序的编译过程。
