我已经使用http://sourceforge.net/projects/witty/files/wt/3.3.5/的安装程序安装了Wt-3.3.5-rc2-msvs2013-Windows-x86-SDK，我正在尝试从此处http://andres.jaimes.net/780/how-to-create-a-first-application-using-wt-witty/构建第一个解决方案并完成了从“为了成功编译这些应用程序中的任何一个，你必须让你的编译器知道额外的include和lib文件夹和文件。”但是我仍然会遇到这种错误，任何想法，为什么？

答案 0 :(得分：1)
您必须区分错误和警告。目前我只读了你日志中的一个错误。
所以，因为只要有一个错误，我们必须查看它。你也有很多警告，但是所有的警告，他们都不会阻止编译。但正如任何警告，你应该知道它们。
我也得到了这些警告，但是因为看起来它们是由Wt的不依赖100％兼容的DLL API，共享链接的windows方式生成的。所以恕我直言，他们可以被忽略，不用担心。
你得到的一个错误，基本上是一个警告，因为微软喜欢假设你是一个转储开发者并且抱怨使用C ++中的函数，可能不安全（称为SDL）。但由于几乎所有C ++语言中的所有内容都是“不安全”，因此C ++在很大程度上依赖于您成为合理的开发人员。 （人们可以在这里提出更多意见:-)）。 这就是为什么我认为你可以忽略这个警告的原因，也因为它的错误＆＃34;错误＆＃34;。
你必须选择处理它
_SCL_SECURE_NO_WARNINGS（可能在项目设置中）来发出警告。
