Hi,

感谢您在此发布。

Thanks for posting here.

您的代码中似乎使用了第三方库，Vec3f似乎与Vuforia更相关。

It seems that you have used the third-party library in your code, the Vec3f seems more related to the Vuforia.

我认为你需要检查包含该符号的第三方库是否已链接。

如果没有，你是可以使用#pragma comment（lib，" lib_path"）或其他链接第三方库的方法，详情请参见此处。

I thinks you need to check if the third-party library which contains the symbol is linked or not.
If not, you could use #pragma comment(lib,"lib_path") or other methods to link the third-party library, more detail here.
