Hi,

Sounds plausible. And I guess for powerpc the root cause is the same,
the libgd-dev shows a version skew between powerpc and amd64.

Tried to do so:
sbuild --host=powerpc -d testing --extra-repository='deb
http://ftp.de.debian.org/debian-ports unstable main'
--extra-repository-key=/usr/share/keyrings/debian-ports-archive-keyring.gpg
texlive-bin
(there is no testing dist for the ports), similar results: some BD's
could not be fulfilled.
Anyway: we have build failures of texlive-bin on sparch64/powerpc very
likely b/c there are too many build threads called in parallel. I would
not have been able to reproduce this issue on my box as my Oracle VBox
VM has only one CPU. ;-)
We need to reduce the # of threads on sparc64 & powerpc. Second try
looks like this:
NO_MASSIVE_PARALLEL_BUILD := powerpc ppc64 sparc64
ifneq (,$(filter $(DEB_HOST_ARCH), $(NO_MASSIVE_PARALLEL_BUILD)))
DEB_BUILD_OPTIONS=parallel=8
endif
This works fine, but now I have a lintian warning:
W: texlive-bin source: debian-rules-sets-DEB_BUILD_OPTIONS line 68
I also tried "MAKEFLAGS += -j8" inside the if statement, but the option
was ignored.
How do I implement the Debian way? Thanks!
