Hi. I'm the openmesh Debian maintainer. The was a build failure building openmesh for 32-bit arm architectures:
https://buildd.debian.org/status/fetch.php?pkg=openmesh&arch=armel&v...
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1067954
I just patched the sources to fix this problem:
https://salsa.debian.org/science-team/openmesh/-/blob/master/debian/patches/...
It would be great if you merge this patch into your tree.
Thanks!
