Experimental Physics and
Industrial Control System

I found that I could get it to build only when I used CONFIG_SITE.local with the following:

# OPENCV is required for the ADPluginEdge plugin
WITH_OPENCV = YES
OPENCV_EXTERNAL = YES
OPENCV_INCLUDE = /usr/include/opencv4
#OPENCV_LIB =

If I used the following then ADPluginBar will build, but any IOC that uses it will fail to build with the error messages already described.

# OPENCV is required for the ADPluginEdge plugin
WITH_OPENCV = YES
OPENCV_EXTERNAL = YES
OPENCV_INCLUDE = /usr/include/opencv4
OPENCV_LIB = /usr/lib

Hopefully this will help someone else in the future. It's a bit confusing because the include files have to be specified because of a change in the location that they are saved for opencv4. Specifying the OPENCV_LIB parameter breaks the build of the IOCs.

Thanks,

Will

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
