Can we unpick this a bit so things that don't link against the bigger libraries don't pull in all these deps? I think separating out the libraries that link against openblas and VTK might be a start.
well, everything seems to link against openblas so getting that out might be hard, but vtk separates out easily. Only libopencv_viz is linked against it.
debian seems to give just about every library its own subpackage: https://packages.debian.org/source/stable/opencv other deps I noted: * only libopencv_text uses libtesseract * only libopencv_ccalib , libopencv_cvv and libopencv_highgui use Qt5
* only libopencv_videostab uses libClp and libCoinUtils
I saw your message on the mailing list and unfortunately, I don't get why gst plugin that uses opencv should be on the default fedora install in the first step ? OpenCV has an outrageous mis-design WRT runtime dependencies: (as referenced in the spec: https://github.com/opencv/opencv/issues/7001), this is known. On my side I've dropped opencv support for some "core" multimedia dependencies on 3rd part (ffmpeg) for this very much reason. Whatever the dependency computation that can be made for a given opencv release, it will be trashed on the next update. So my advice is to drop the gst plugin using opencv as a sub-package and enforce it not into the default Fedora install set of packages. Is that good for you ?
I mean, they're two different issues. We already changed the gstreamer plugins package, but plenty of other things use opencv and so its giant dep tree affect them. I already suggested a pretty simple change here: just split each openxv lib into its own sub package, so other things that build against opencv only pull in the library sub package(s) and associated deps they actually need. If something only links against the core lib, for e.g., this would save it pulling in qt5 and java and vtk and all sorts of other things. Is there any reason we can't do that?
I don't know how many issues to count for this problem, but one other aspect of the same issue is that some opencv users links to all opencv core libraries no matter of which one they really use (mainly because they use the broken opencv.pc/cmake). So splitting into sub-package without fixing theses will be pointless in theses cases.
Note that I'm open with improvement with further sub-packaging opencv libs. I'm not yet sure to prefer sorting libs in sub-packages by dependencies cost over having a each single lib it own sub-package.
Well, I just did a quick dumb check on this. Here's the results: PACKAGE REQUIRING LIBOPENCV_CORE DOES IT REQUIRE ALL OPENCV LIBS? OpenImageIO NO YafaRay-lib NO digikam-libs NO frei0r-plugins-opencv NO gmic YES libfreenect-opencv NO lives NO nomacs NO nomacs-plugins NO opencv NO opencv-contrib NO opencv-devel YES opencv-java NO os-autoinst NO performous NO php-facedetect YES player NO python3-opencv NO (most, but probably needs to) qimgv NO simarrange YES siril NO waifu2x-converter-cpp NO so, there's four packages that could probably be improved, but the significant majority of packages that require opencv_core do not require all the other libs too (they mostly require only 2-4 of them).
this commit [1] should change a lot of dependencies because many modules change from core to contrib and vice-versa [1] https://src.fedoraproject.org/rpms/opencv/c/0a5887a0d1dd62efec577ab7daa161e525ea5af2?branch=rawhide
This message is a reminder that Fedora 33 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora 33 on 2021-11-30. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '33'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 33 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
