Emilio suggested uploading now to save a round-trip, so I just
uploaded 22.1.8-1~deb13u1 to trixie. I've attached the diff between
22.1.8-1 and 22.1.8-1~deb13u1, though it's really the same as the
previous 22.1.7-1~deb13u1.
The packages as uploaded to NEW have some dependency issues:
pkg:
package: liboffload-22
version: 1:22.1.8-1~deb13u1
architecture: amd64
unsat-dependency: libomp5 (>= 1:22.1)
trixie has libomp5 1:19.0-63.
Is that "just" a sign of the packages not being built in the correct
environment, or something that needs source changes?
D'oh, I think I see the problem. d/rules has the following:
echo 'libomp $(SONAME_OPENMP) libomp5 (>= 1:$(LLVM_VERSION).1)' >>
debian/shlibs.common
I'll fix it and kick off another rebuild soon.
Okay, that took a little longer than expected because building chromium
on trixie with llvm-toolchain-22 broke (related to trixie's older
bindgen), but we have a workaround for chromium and I was able to test
chromium builds with this new ~deb13u2 package.
I've attached the full debdiff between sid's version and this backport,
but the only non-changelog difference between ~deb13u1 and ~deb13u2 is
the bit at the end:
