Both bear and fmidi are now rebuilt into the side tag. I defined the preprocessor macro FMT_DEPRECATED_OSTREAM as a temporary workaround (noting that this will not be available in fmt 10.0). I filed an issue upstream with fmidi: https://github.com/jpcima/fmidi/issues/5

Two of the three packages I tried to rebuild (bear and fmidi) failed with errors like:

I found that there was already a bug report open upstream for Bear: https://github.com/rizsotto/Bear/issues/471

If that FTBFS rate is typical of the full set of affected packages, then merging the side tag without resolving the API incompatibilities in dependent packages will be pretty disruptive to Rawhide as a whole.

Would you consider setting up a COPR to figure out how many packages are affected by the API changes, and filing Bugzillas on the affected dependent packages? It might take a while for affected package maintainers to become aware of the problem, investigate, and perhaps work with upstreams to prepare the necessary patches.

I don’t believe this list is nearly complete. Two packages I maintain that would be affected (fmidi and giada) are absent from the list.

Using the following command:

mock -r fedora-rawhide-x86_64 --dnf-cmd -- repoquery --whatrequires 'libfmt.so.8*'

I found these additional dependent packages that were missing from the original list:

bear

cachelib

easyeffects

easyrpg-player

fb303

fbthrift

fizz

fmidi

freeopcua

gerbera

giada

gnuradio

gr-funcube

libsemigroups

luxcorerender

mcrouter

nheko

proxygen

rstudio

wangle

watchman

waybar

I will go ahead and rebuild bear, fmidi, and giada into the side tag.

Hello.

fmt 9.0.x update will include a soversion bump from .8 to .9. It has both API and ABI changes.

Changelog: https://github.com/fmtlib/fmt/releases/tag/9.0.0

The list of affected packages in Rawhide:
0ad
OpenImageIO
cantera
ceph
dolphin-emu
domoticz
folly
libsonata
mkvtoolnix
sdrpp
spdlog
vcpkg
zswap-cli

I can rebuild only spdlog, vcpkg and zswap-cli. For others, I will need proven-packagers assistance.

Please use the f37-build-side-54844 side tag. I will merge it into Rawhide later.
