Failed to upgrade opencv @3.2.0+contrib+python36 to opencv @3.4.1_2 Mac OSX Sierra

[fmw42 (Fred Weinhaus)]

I first did sudo port selfupdate. Then I upgraded all my outdate ports except opencv, which failed. I then tried sudo port clean opencv, which failed. I then tried to install opencv manually via sudo port install opencv +contrib+python36

My steps and log file are attached. I am on Mac INTEL Mini OSX Sierra 10.12.6.

Any updates on when this might get fixed? It is still an issue with the latest MacPorts and OpenCV port as of 11/8/2018

The +contrib variant is broken:

Looks like an upstream bug, to be sure.

Can you use opencv without the +contrib variant? It's not a default variant anyway and who knows when (if ever) it might be fixed upstream.

[fmw42 (Fred Weinhaus)]

Thanks for the reply. I was using SIFT from the contrib. But I will try without the contrib and see if I can even get OpenCV installed without it. Let you know what happens.

Any idea if this is an OpenCV issue or MacPorts or cmake issues?

Would changing the dependency on protobuf-cpp to protobuf3-cpp in the Portfile fix this?

install opencv +python37

[fmw42 (Fred Weinhaus)]

Today, I upgrade MacPorts and my outdated ports. I then tried sudo port install opencv +python37 (without +contrib). But it failed as follows:

But I do have installed gegl-0.4 @0.4.12_2+x11 (active)

Can you suggest what I can do about this?

See the attachment for the details and all my installed ports.

Thanks.
