if you’re looking to get support for some kind of `raspicam` library, or how to wrangle Geany, you’re in the wrong place. this is the OpenCV forum.

“undefined reference” is a generic C++ compiler issue.

again, you’re in the wrong forum.

the error talks about `raspicam` (all OpenCV stuff seems to have worked). this is not supported here. this is the forum for OpenCV, not raspberry pi or its peripherals.

please seek help on [https://forums.raspberrypi.com/](https://forums.raspberrypi.com/) or [Issues · cedricve/raspicam · GitHub](https://github.com/cedricve/raspicam/issues)
