Bug#1120447: Zoneminder in trixie not functional in armhf architecture
Package: zoneminder
Version: 1.36.35+dfsg1-1
Severity: important
X-Debbugs-Cc: debian-arm@lists.debian.org, burban@fdn.fr
User: debian-arm@lists.debian.org
Usertags: armhf
Hi!
I have used zoneminder successfully up to bookworm on armhf (a Cubox
for the record) with one USB camera and one IP camera.
After upgrading to trixie, process zmc crashes quickly:
(below from /var/log/zm/zmdc.log)
11/06/25 12:04:35.703746 zmdc[24875].INF [ZMServer:411] [Starting pending process, zmc -d /dev/video4]
11/06/25 12:04:35.777008 zmdc[24875].INF [ZMServer:411] ['zmc -d /dev/video4' starting at 25/11/06 12:04:35, pid = 25125]
11/06/25 12:04:35.777041 zmdc[25125].INF [ZMServer:411] ['zmc -d /dev/video4' started at 25/11/06 12:04:35]
11/06/25 12:04:36.126975 zmdc[24875].INF [ZMServer:716] ['zmc -d /dev/video4' crashed, signal 10]
The other processes of zoneminder are running ok, the apache web
server is functional; but no a single camera picture to visualize.
I have also run zoneminder with the sames cameras on a classic amd64
PC, and everything worked flawlessly. So an architecture related
problem is likely.
I recompiled zoneminder package with debugging info, both on amd64 and
armhf. There were a couple of C++ compilation warnings on amd64 of the
pedantic nature, but far more for armhf, and potentially serious,
mostly related to time_t, below an excerpt:
~/sources/zoneminder/zoneminder-1.36.35+dfsg1/src/zm_event.cpp:96:11: warning: format ‘%ld’ expects argument of type ‘long int’, but argument 9 has type ‘__time64_t’ {aka ‘long l
ong int’} [-Wformat=]
~/sources/zoneminder/zoneminder-1.36.35+dfsg1/src/zm_event.cpp:96:11: warning: format ‘%ld’ expects argument of type ‘long int’, but argument 10 has type ‘__suseconds64_t’ {aka ‘
long long int’} [-Wformat=]
If I run gdb (only my USB camera was plugged in for this test):

It is easy to drop the call to Logger::logPrint by suppressing logging to database, which then gives:

Quit anyway? (y or n) y
root@cubox:~#
Here we can avoid the call to Monitor::Analyse by unchecking "Analysis
Enabled" in my camera configuration "Modect"; then the zmc process
isn't killed anymore, and I can view the camera video on the web
server! But you don't use zoneminder if you don't need motion
detection, so this isn't a solution.
I believe this is solely a Debian packaging issue (due to the early
commitment of the project to 64 bits time_t), but it may become an
upstream issue.
For the record considering upstream, there was recently a close bug
for a Raspberry PI 2B, which I believe is also armhf:
