Cross compile error

[AkkiSony]

Hey @larrylart, During compilation of he code on VIM3, did you do it using cross compiler? If so, does this demo work using cross compiler?

[larrylart]

Hi @AkkiSony, no I didn't cross-compile. It seems that you are missing opencv4.

Hi @larrylart, Thank you for the clarification. I have installed OpenCV4 already in the virtual environment! Do, I have to set the path somewhere?
I am currently running this 'make' on host PC (Ubuntu 18.04). Hope, I am doing it right? I assumed this because in the make file, it requires us to set the path to SDK. SDK lies in the host PC (Ubuntu 18.04).

Please give me a clarity. Does this demo run on PC or on khadas board?

@larrylart. I guess, I had to run it on VIM3.

I got the following output. What am I missing? :/
