Fedora 39 Plots Path For Intel Threaded Building Blocks Upgrade
The past five Fedora Linux releases they have stuck to shipping the now three year old Threaded Building Blocks 2020.3 release due to backwards incompatible breakage following that release. Due to a number of software packages out there still depending upon the old TBB interface, there isn't a trivial path forward for upgrading the TBB packaging on Fedora.
A change proposal has been filed so that during the Fedora 39 cycle they can work on updating against oneTBB 2021.8 while keeping a compatibility package for TBB 2020.3 for software still depending upon the older version. The compatibility package will have the legacy headers installed in a different location so software not yet able to use the modern oneTBB API will need to be updated for the changed location of the headers. Installing the development files and run-time support for both the old and new (one)TBB will be possible on Fedora 39.
