Problems building melodic compressed_depth_image_transport on 18.04

Question

Following these instructions to do a source build of melodic desktop full (I want to build it with thread sanitizer because of something I'm debugging): http://wiki.ros.org/melodic/Installation/Source

I'm getting this error, I know it has to do something with OpenCV versions but I can't figure out how to fix it.

Answer 1

Do you have OpenCV 3.4 or 4.x installed?

According to ros-perception/image_transport_plugins#54 and a bunch of other Google results, those flags were renamed quite a few times between 2018 and now.

Melodic targets OpenCV 3.2 on Ubuntu 18.04 (see Melodic Morenia (May 2018 - May 2023) in REP-3). And with that: not the upstream version, but:

" * " means that this is not the upstream version (available on the official Operating System repositories) but a package distributed by OSRF or the community (package built and distributed on custom repositories).

You'll have to make sure you have that version or if you have others, CMake finds the required version first.

That was it, thank you. I have 4 installed because we are using it for a project that has another external dependency that depends on 4. I got by this by putting CATKIN_IGNORE filles in the two packages that wouldn't build in ros as searching my code I don't think we use them.

Seeing some of your other questions (here and on the MoveIt issue tracker(s)), I would perhaps suggest to look into using containers more.

I do use containers when I have to, but perhaps I should use them more.
