Hello Fedora packagers,
OpenVDB 13.1.0 has been released and introduces a shared-library SONAME change:
libopenvdb.so.13.0 -> libopenvdb.so.13.1
This requires coordinated rebuilds of packages that directly link against OpenVDB, as well as source packages that consume openvdb-devel.
The direct runtime consumers of libopenvdb.so.13.0 are:
OpenImageIO blender luxcorerender usd
Source-level dependency analysis also identifies:
manifold openvkl
as consumers of openvdb-devel.
The complete transition set is therefore:
openvdb OpenImageIO blender luxcorerender manifold openvkl usd
OpenVDB 13.1.0 provides:
libopenvdb.so.13.1()(64bit)
The update is planned for:
Fedora Rawhide Fedora 45
I do not plan to introduce this ABI-changing update into older stable Fedora releases.
The transition is tracked in:
Bug 2535782 OpenVDB 13.1.0 SONAME transition tracker
The individual package bugs are:
Bug 2535783 - openvdb Bug 2535784 - OpenImageIO Bug 2535787 - luxcorerender Bug 2535789 - manifold Bug 2535790 - openvkl Bug 2535791 - usd Bug 2535792 - blender
The following Koji side tags have been created for the transition:
Rawhide / Fedora 46:
f46-build-side-151928
Fedora 45:
f45-build-side-151930
The side-tag build commands are:
For Rawhide:
fedpkg build --target=f46-build-side-151928
For Fedora 45:
fedpkg build --target=f45-build-side-151930
To wait for the corresponding build repositories to be regenerated:
koji wait-repo f46-build-side-151928
koji wait-repo f45-build-side-151930
The planned side-tag rebuild order is:
Stage 1:
Bug 2535783 - openvdb
Build OpenVDB 13.1.0 first in both side tags.
Stage 2:
Bug 2535784 - OpenImageIO Bug 2535787 - luxcorerender Bug 2535789 - manifold Bug 2535790 - openvkl
These packages can be rebuilt after OpenVDB 13.1.0 is available in the respective side-tag buildroot.
Stage 3:
Bug 2535791 - usd
usd BuildRequires OpenImageIO-devel, so it must be rebuilt after the updated OpenImageIO build is available.
Stage 4:
Bug 2535792 - blender
blender should be rebuilt last because it BuildRequires:
OpenImageIO-devel usd-devel manifold-devel
The dependency relationships are therefore:
Bug 2535784 - OpenImageIO Depends On: Bug 2535783
Bug 2535787 - luxcorerender Depends On: Bug 2535783
Bug 2535789 - manifold Depends On: Bug 2535783
Bug 2535790 - openvkl Depends On: Bug 2535783
Bug 2535791 - usd Depends On: Bug 2535783 - openvdb Bug 2535784 - OpenImageIO
Bug 2535792 - blender Depends On: Bug 2535783 - openvdb Bug 2535784 - OpenImageIO Bug 2535789 - manifold Bug 2535791 - usd
All package bugs block:
Bug 2535782 - OpenVDB 13.1.0 SONAME transition tracker
The effective build dependency graph is:
openvdb | +--> OpenImageIO --> usd --> blender | +--> manifold ------------> blender | +--> luxcorerender | +--> openvkl
Additional packages such as:
embree materialx oidn olive openshadinglanguage
BuildRequire OpenImageIO-devel, but they are not direct OpenVDB consumers and are not currently expected to require rebuilds solely for this SONAME transition.
The transition will be coordinated entirely through the side tags listed above so that OpenVDB and all affected packages can be rebuilt and tested together before being merged into the main repositories.
After each build stage, the corresponding side-tag repository should be regenerated before starting packages that depend on the newly built artifacts.
For Rawhide:
koji wait-repo f46-build-side-151928
For Fedora 45:
koji wait-repo f45-build-side-151930
After all rebuilds are complete, the transition will be considered ready when:
1.
OpenVDB 13.1.0 builds successfully in both side tags.
2.
OpenImageIO, luxcorerender, manifold, and openvkl build successfully against the new OpenVDB.
3.
usd builds successfully against the updated OpenImageIO/OpenVDB stack.
4.
blender builds successfully against the updated OpenVDB, OpenImageIO, USD, and Manifold stack.
5.
No affected external package still requires:
libopenvdb.so.13.0()(64bit)
6.
Direct OpenVDB consumers instead require:
libopenvdb.so.13.1()(64bit)
7.
Applicable package test suites pass.
8.
Both completed side tags have no broken dependencies and are ready to be merged.
If you maintain another package that directly links against OpenVDB or builds against openvdb-devel and it is not listed above, please let me know so it can be investigated and added to the transition if necessary.
Thank you for your help with the transition.
Best regards,

Hello Fedora packagers,
Following the OpenVDB 13.1.0 SONAME transition, the Fedora 46 / Rawhide side tag currently has a build failure caused by recent Rawhide changes affecting the OpenCV/OpenVDB stack:
https://koji.fedoraproject.org/koji/taskinfo?taskID=150533990
The affected side tag is:
|f46-build-side-151928|
The Fedora 45 transition, using:
|f45-build-side-151930|
is nearly complete. At this point, |openvkl| is the remaining package that needs to be rebuilt against OpenVDB 13.1.0, along with its Rawhide counterpart.
Because I do not have commit access to |openvkl|, and following the response from its primary maintainer, I would appreciate help from a proven packager who has the necessary access to rebuild |openvkl| in both side tags:
|Rawhide / Fedora 46: f46-build-side-151928 Fedora 45: f45-build-side-151930 |
The corresponding build commands are:
|fedpkg build --target=f46-build-side-151928 fedpkg build --target=f45-build-side-151930 |
|openvkl| is tracked as part of the OpenVDB 13.1.0 SONAME transition under:
*
Bug 2535782 — OpenVDB 13.1.0 SONAME transition tracker
*
Bug 2535790 — openvkl rebuild
Completing these builds would allow the Fedora 45 transition to move toward completion and would also advance the Rawhide transition once the unrelated Rawhide build issues are resolved.
Thank you for your help with the transition.

Weird to the point of leaving the head scratched in Rawhide. It seems like the logical option is to rebuild openvdb to resolve the issue unless an alternative exists.
Thank you for taking care of the rebuild.
The F45 build succeeded: https://koji.fedoraproject.org/koji/taskinfo?taskID=150563829
Great! You can push the F45 build when completed.
I will push f46-build-side-151928 for now. The Rawhide side-tag managed to become messier than anticipated due to opencv issue in addition of unexplained requirement of openvdb despite the rebuilt.
