Hi Marcin,
As Mark said, ADCompVision is a plugin that uses OpenCV more thoroughly than ADPluginBar, and may be a better starting point.
For the errors, if you are using OpenCV from a system location, make sure to comment out OPENCV_LIB and OPENCV_INCLUDE definitions in
CONFIG_SITE.* files. If these are defined and linking to system libraries you may run into such undefined reference errors.
Best,
Jakub

You may be able to use that directly, or use it as a starting point.

I use ADPluginBar as a reference, following instructions from https://github.com/areaDetector/ADPluginBar I made required changes to the areaDetector installation and both ADPluginBar and my plugin compiles successfully with areaDetector. However, when I try to compile IOC with ADPluginBar, I get undefined reference errors, like: /usr/local/epics/support/areaDetector/areaDetector-R3-8/ADPluginBar/lib/linux-x86_64/libNDPluginBar.so: undefined reference to `cv::Mat::deallocate() I assume that in my IOC I need to link only ADPluginBar and there is no need to directly link external libraries (OpenCV and zbar). Is that correct? What I'm missing? Has anyone have an example of IOC with ADPluginBar or custom ADPlugin which uses external library, like OpenCV? My environment: base: 7.0.3.1 asyn: 4-38 areaDetector: R3-8 OpenCV: 2.4.13.6 (installed from the source, to the default system location) I appreciate any suggestion or feedback. Thanks Marcin |
