Metro ap create a c++ opencv application error :'CoCreateInstanceFromApp': identifier not found

Question

Hi ,

I create a c++ opencv application,error:'CoCreateInstanceFromApp': identifier not found when I bulid it.

Can anyone help to answer this question?

Answer 1

If this isn't a Metro style app project then this is likely not the correct forum for this question.

If you are using a metro style app project, could you elaborate on your project type and the exact build error? A snippet of the source failing to compile would be useful as well. The syntax for that desktop Win32 API is here: CoCreateInstanceFromApp

 

Thanks,

-David

Answer 4

I had this same problem, in my case it was an old library that I was trying to port to winrt and I had defined somewhere #define _WIN32_WINNT 0x0601. Changing it to #define _WIN32_WINNT 0x0602 solved the issue for me.
