Superslicer (media-gfx/superslicer-2.3.57.11:23/23::guru) will not attempt to build due to blockage of dependency packages. The media-libs/ilmbase-2.5.7-r3 blocks install of media-libs/openexr-3.1.4-r1 due to conflict with dev-libs/imath-3.1.4-r3. The media-libs/ilmbase-2.5.7-r3 and media-libs/openexr-3.1.4-r1 are direct dependencies of media-gfx/superslicer-2.3.57.11 and possibly older versions. Reproducible: Always Steps to Reproduce: 1. Enable guru repository 2. Set necessary accept_keywords 3. Set necessary use flags 4. Attempt to emerge superslicer Actual Results: I received the same results on two systems, one a recent install and one was installed in late 2019. # emerge -av superslicer Calculating dependencies... done!

media-gfx/superslicer needs to be adapted to work with OpenEXR 3. It should drop the ilmbase dependency if possible (if it works with OpenEXR 3) and change to imath or >=openexr-3:0= if appropriate. See https://github.com/gentoo/guru/blob/master/media-gfx/superslicer/superslicer-2.3.57.9-r1.ebuild.
All builds from the guru repo are failing for me with the same results. Is it possible I have a USE flag causing this on the older builds?

According to the build system (version 2.3.57.11), the package itself does not depend on OpenEXR. It checks whether OpenVDB is built with support for OpenEXR, in which case it links against the OpenEXR / ILMBase libraries. The minimal required OpenVDB version is 5.0. It's possible, that this old version didn't solve the link dependencies correctly. However, later versions (8.0 and later, maybe 7.0 as well) should do proper linking, so their build system would not need to explicitly link against OpenEXR and ILMBase libraries. Also, the support for OpenVDB is optional. So, the ebuild could add an openvdb USE flag and depend on >=openvdb-8. OpenVDB pulls in the proper OpenEXR libraries if set and the package doesn't need to depend on either ilmbase or openexr at all. The build system eventually needs some patching to avoid explicit linking against ilmbase and openexr libraries (in CMakeLists.txt and cmake/modules/FindOpenVDB.cmake). OpenVDB *should* properly link against the correct OpenEXR libraries. If this doesn't work out, the package needs to restrict their openexr dependency to <openexr-3. Most packages nowadays already support openexr-3, so this can lead to package collisions, if another installed packages requires >=openexr-3.
Created attachment 789974 [details] fixed ebuild
Created attachment 789977 [details, diff] fix required for boost 1.79
Created attachment 789980 [details, diff] fix for handling tbb version > 2020
I was able to fix the openvdb cmake error, a bug with tbb 2021 (adapted from a patch found somewhere on github), and a build failure with boost 1.79 (deprecated filesystem::fstream). Haven't tested much yet but it compiles and runs.
I believe this also needs a dev-cpp/tbb:= built slot dep
I confirm that SS 2.5.59.0-r1 builds and appears to run fine. Thank you all.
