Greetings, I used git to grab the repository, compiled and installed it.

Then, I attempted to grab another repository (aero-optical-flow) and I can't build it.

/usr/src/aero-optical-flow/modules/OpticalFlow/include/flow_opencv.hpp:44:16: fatal error: cv.h: No such file or directory

So, i searched the repo for opencv I pulled and.. well, there isn't any cv.h, so it wouldnt have installed it. I'm not really sure what is missing.

cv.h does exist on a different (debian) system I have, and the package is 'libopencv-dev'.

However, this is not a debian system, and there are no packages. So I have to install from source. I'm just confused about why the repository I pulled for opencv doesn't also have this. So, it must be somewhere else?

Thanks!

cv.h is from the opencv1.0 C-api, deprecated since like 10 years ago.

your aero-optical-flow repo is simply out of date, as well as your debian package

if you want my 2 ct: abandon it, and look for a more modern (c++ !) and better maintained approach

Good stuff, thank you. This is a different service but the same idea worked just fine!
