Dear Tech-Talk, 

I am trying to use opencv with areaDetector. To start, I have been trying to build with the ADPluginEdge plugin

I am using ubuntu 20.04
I have pulled AD 3-12-1
I have installed opencv using the package manager. sudo apt install libopencv-dev
I have checked that the commonDriverMakefile in ADCore contains ifdef ADPLUGINBAR....
I have checked that in CONFIG_SITE.local.linux-x86_64 the following is set

WITH_OPENCV = YES

OPENCV_EXTERNAL = YES

I had to add the include directory because opencv 4.2.0 includes are under /usr/includes/opencv4

OPENCV = /usr

OPENCV_LIB = $(OPENCV)/lib

OPENCV_INCLUDE = -I$(OPENCV)/include/opencv4

ADSupport, ADCore and ADPluginEdge build without errors. Then when I try to build an example IOC using ADSimDetector I get the following error:

No rule to make target '../../../lib/linux-x86_64/libopencv_core.a', needed by 'simDetectorApp'

It feels like it isn't looking in the EXTERNAL location like I tell it to. Have I missed something? Does anyone have a suggestion?

Thanks, 

Will
