Hello, everyone.

There are some problems with OpenCV, which I hope you could help me to solve.

I compiled OpenCV for Windows 10 x86_64, and now I try to run some samples.

How I did that?

I configured it with CMake, to use MSBuild VS2015.

Built to a separate directory, then made:


Then I copied the contents of the "install" subdirectory to a separate directory and added the x64/vc14 directory to the PATH.

No I am trying to run samples from "x64\vc14\samples\directx"

For example:


Crashes with the following log:

            print help info

Then I tried to run examples from "x64\vc14\samples\tutorials"

For example, I chose a file

So basically, it's too long to get through, but I wonder if there is at least one example in OpenCV which is not broken and could show me that the installation is actually working?
