Description
I have OpenCV installed through MacPorts, and when I go to install OpenCV4 I get:
---> Computing dependencies for opencv4 Error: Can't install opencv4 because conflicting ports are active: opencv Error: Follow https://guide.macports.org/#project.tickets to report a bug. Error: Processing of port opencv4 failed
So I'm guessing only one version of OpenCV can be installed?

But just to be clear, that is a bug. If we want to provide multiple ports for different versions of a software package, we should do so in such a way that they do not conflict.
(The exception is -devel ports.)

Presently, only two ports are dependent on opencv4: Gerbil and py-pytorch. So if this is going to be fixed, now would be a great time... before more dependent ports are added.
I'll volunteer to update py-pytorch, since there's no maintainer. I'd also be willing to update Gerbil, with Clemens' blessing.

Looking at what the two opencv ports install, there are very few conflicts. So it looks like the opencv4 changes necessary, will be fairly minimal. Ditto for the changes to the two dependents.
opencv installs:
/opt/local/bin/opencv_annotation /opt/local/bin/opencv_createsamples /opt/local/bin/opencv_interactive-calibration /opt/local/bin/opencv_traincascade /opt/local/bin/opencv_version /opt/local/bin/opencv_visualisation /opt/local/bin/opencv_waldboost_detector /opt/local/bin/setup_vars_opencv3.sh /opt/local/lib/libopencv_*.dylib /opt/local/include/opencv/* /opt/local/include/opencv2/* /opt/local/lib/pkgconfig/opencv.pc /opt/local/share/OpenCV/* /opt/local/share/licenses/opencv3/*
While opencv4 installs:
/opt/local/bin/setup_vars_opencv4.sh /opt/local/bin/opencv_interactive-calibration /opt/local/bin/opencv_annotation /opt/local/bin/opencv_version /opt/local/bin/opencv_visualisation /opt/local/lib/libopencv_*.a /opt/local/include/opencv4/* /opt/local/lib/opencv4 [presently empty, apart from '3rdparty' subdirectory] /opt/local/lib/opencv4/3rdparty/* /opt/local/lib/cmake/opencv4/* /opt/local/share/opencv4/* /opt/local/share/licenses/opencv4/*
Assuming I didn't miss anything (?), only two things need changes:
- Libraries (move down one level, into
/opt/local/lib/opencv4/) - Binaries (rename to
opencv4_*?)

Currently building opencv4 with all variants enabled, to identify other potential conflicts.
comment:7 Changed 4 years ago by mascguy (Christopher Nielsen)
Even with all variants enabled, there don't appear to be any other conflicts beyond what's mentioned above. So that's good news.
comment:8 Changed 4 years ago by mascguy (Christopher Nielsen)
Andrew, since I have a need for opencv4, I'm willing to take on this work. Let me know if that's okay with you.
comment:9 Changed 4 years ago by mascguy (Christopher Nielsen)
Most of this work has been completed, taken care of with additional options passed to configure. The last remaining remnant originates with variant opencv_contrib, and may require a one-line workaround in the portfile.
I'll try to wrap this up over the next day or two, and submit a pull request for review/comment.

FYI: gmic builds against opencv4.

Replying to Schamschula:
FYI: gmic builds against opencv4.
Marius, it looks like gmic depends on opencv, rather than opencv4.

Yes, they have been marked as conflicting ports. I would guess that since they are different versions of the same software, they try to install many of the same files.
