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 1 complete. Next stage below is:

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.

Please use these side tags:

For Rawhide:

fedpkg build --target=f46-build-side-151928

For Fedora 45:

fedpkg build --target=f45-build-side-151930
