I tried some more things: - building everything with gcc-8 (version Debian 10 uses, where Jami works) - using dependency tarballs from pjproject source instead of Guix packages, you can see this mess on my gitlab repo on wip-pjproject-fix branch https://gitlab.com/kromka_chleba/jami-package-and-other-things-for-guix
As I said before, I'm out of ideas how to fix the problem. Jan Wielkiewicz
