Hi. Thanks for the report. I just uploaded a new upstream version (4.2.2), and I don't see this FTBFS problem:
https://buildd.debian.org/status/package.php?p=gtsam It MIGHT still be an issue. These kind of failures have popped up periodically (and were fixed) in this project earlier. And the same things are happening today with the failing 32-bit builds: https://buildd.debian.org/status/fetch.php?pkg=gtsam&arch=armhf&ver=4.2.2%2Bdfsg-3&stamp=1784867632&raw=0 https://buildd.debian.org/status/fetch.php?pkg=gtsam&arch=i386&ver=4.2.2%2Bdfsg-3&stamp=1784867950&raw=0 Upstream knows about the 32-bit failures, and hopefully they'll fix them (and hopefully other similar things) in a new upstream release. I'd like to close THIS bug until we can clearly reproduce it. Sounds reasonable? Thanks
