I have tried opencv 2.4.8.2, 2.4.7.1, 2.4.9 and it fails for all of them. Also I was on cmake 3.1.3, but moved to cmake 2.8.12.2 - still the same issue. Any idea how to resolve it?
I recently updated rbind & ropencv and there was a small period of time where rbind was not compatible to ropencv. Therefore, can you try to install it again and report if you still encountering problems (which OS are you running?).
you are right, it works now! thanks a lot.
