I have built the opencv 4.6.0 from the source code with cuda dnn support.

I am getting these errors on compiling the project.

you’re trying to link release libs to a debug build.

These were my cmake settings
with_cuda : True
cmake_configuration_type : Release
…

That means I am using release configuration from opencv and also release configuration from my code as you can see here.
E:\FFTAI\ai-plugin\out\build*x64-Release*\api.cpp.obj

Can you again explain what exactly you meant here. I didnt catch you completely.

i cant see anything on your box, dear :slight_smile:

means, it expects the DEBUG version of the resp. library
