It looks like you have build using older makefiles with newer code.
With the side effects that some cpp files didn't get included. Try and
cleanup your environment et rebuild from scratch.

This usually happens if you disable maintainer mode in configure, you
have disabled some timestamp on your file system or you have change the
time on your system.

Re: opencv plugin problem

tasos-2
You are right.
I had to make clean && make distclean and then used configure with
enable-mainterer-mode (which previously i had disabled).
Thank you very much!

Glad it works now. For the record:

If you do a single build -> disable-maintainer-mode
If you are going to update and build -> enable-maintainer-mode

Or use meson build system, it only run in equivalent of maintainer mode, but without the overhead.
