Apparently it has something to do with opencv 2 vs opencv 3. I have opencv 3.1.0 here on Archlinux.

It still builds with

cmake -DPSMOVE_USE_DEBUG=1 -DPSMOVE_BUILD_EXAMPLES=0 -D PSMOVE_BUILD_OPENGL_EXAMPLES=0 -DPSMOVE_BUILD_TESTS=0

so it's not critical for debugging, but still annoying

Has OpenCV 3 removed those functions? Or put into another header?

See opencv/opencv#6076, opencv/opencv#6585.

Is the only way to get around this issue either using OpenCV2 with C or use OpenCV3 with C++?

Well, it looks as if that is the case. To be honest, I do not even know why the update to OpenCV 3 has been made for PS Move API. Should have sticked to 2.x ...

I just tried building in ubuntu 22.04 using:

scripts/build_package.sh

This builds OpenCV 3.4 from source, and PS Move API successfully links against it.

The affected test application has been removed in 2016 already: #277
