were there any errors while you pressed either the configure or generate button in CMKAE-GUI? or have you correctly followed the document?

Ok i was able to reproduce your issue, you are missing almost all the Linker Input files.
The specific one that threw that error was opencv_highgui330.lib. Please make sure you have all the Linker Input files.
Following the #5. from this article and add all the relevant one’s.
Whenever you see any unresolved external symbol errors, that means you are missing on the External Dll’s or Libs.
Hope this helps

Are you using x64 project build and also debug build since you are not using release binaries?

But then it showed another error. i got error code “LNK2001 unresolved external symbol “void __cdecl cv::imshow(class cv::String const &,class cv::_InputArray const &)” (?imshow@cv@@YAXAEBVString@1@AEBV_InputArray@1@@Z) opencv test2 C:\Users\Lenovo\Documents\Visual Studio 2015\Projects\opencv test2\opencv test2\Source.obj 1 ”

Hey thank you for this tutorial! i have a little bit of problem though. i tried the test code for live feed webcam that you gave, but then an error showed up saying cannot open input file ‘opencv_core330.lib’. I have open “C:\opencv_git\mybuild\install\x64\vc14\lib” and there i found ‘opencv_core330d.lib’. i do not know what’s wrong.

can you navigate to “C:\opencv_git\mybuild\install\x86\vc14\lib” and check what all Lib files you have in there? Do you see any file with core in it?
