I see. With the patch from that bug it still doesn't work, because
tesseract.pc requires lept.pc, which is also not in the multi-arch
location. I've filed #841968 about that.
With both these fixed, ffmpeg can be cross-built successfully,
so it is definitely not affected by #841827.

By the way, thanks for all your work on cross-build support!

Best regards,
Andreas

Control: affects -1 = src:pulseaudio

Actually, no. I only managed to reproduce it for pulseaudio now, though
I vaguely remember another practical reproducer.

Yes, that's #841845.

Are you sure this affects ffmpeg?

As far as I can tell its build doesn't execute orcc.
The cross-build currently fails due to:
ERROR: tesseract not found using pkg-config

Bug#841827: liborc-0.4-dev: cannot run orcc during cross compilation of reverse dependencies

[Helmut Grohne]

Package: liborc-0.4-dev
Version: 1:0.4.26-1
Tags: patch
User: helm...@debian.org
Usertags: rebootstrap
Control: affects -1 + src:buzztrax src:ffmpeg src:gnuradio src:gst-libav1.0 
src:gst-plugins-base1.0 src:gst-plugins-good1.0 src:libquicktime src:lives 
src:mplayer src:pulseaudio src:schroedinger src:uhd

Cross compiling the packages listed above results in a failure to
execute orcc. orcc resides in liborc-0.4-dev which is usually a host
architecture dependency and thus orcc also is a host architecture
executable, which cannot be run.

I propose splitting liborc-0.4-dev into liborc-0.4-dev-bin. The latter
would take over the binaries from liborc-0.4-dev. Since at least
orc-bugreport looks like it has architecture-dependent output, I don't
think we can mark it Multi-Arch: foreign. Thus I propose marking
liborc-0.4-dev-bin Multi-Arch: allowed and having liborc-0.4-dev depend
on liborc-0.4-dev-bin:any. Practically, this results in
liborc-0.4-dev-bin being installed for the build architecture and thus
fixing cross builds.

Please consider applying the attached patch.  If you have more insight
into what these binaries do, consider using Multi-Arch: foreign if that
is appropriate. You may have to adapt the versions listed in Breaks and
Replaces.
