cannot catkin build package in melodic

[PhilipAmadasun]

I get CV related errors when I try to catkin build package in melodic:

error: ‘CV_DIST_L2’ was not declared in this scope
error: ‘CV_FILLED’ was not declared in this scope
error: ‘CV_RETR_CCOMP’ was not declared in this scope
.................................

Perhaps my openCV version is not compatible I'm not sure. I need to make sure what the problem is.

Dear Philip,

thanks for the interest in our software. Could you please tell me which branch you're trying to build and what version of OpenCV you have installed?

Best regards

I have opencv libraries for python and c++, but I don't just have opencv installed outside of those. What version should I install?

Could you please run apt-cache policy libopencv-dev and paste the output to here? In principle in melodic we assume the (standard) version 3.2.0 for this.

Also we provide the melodic_dev branch for versions before noetic, so you should also switch to this branch if you want to use the code in melodic. Can you please also make sure you checked out to this branch?

Have you solved this? I met the same error as you and my libopencv-dev version is 3.2.0+dfsg-4ubuntu0.1
