Any idea how to resolve that issue?

Hi Ottega, the issue is related to GCC 12.1. Please try to apply the patches (0001..0005) included in https://aur.archlinux.org/packages/srsran-git

[robertfalkenberg]

You could also try this branch, which already includes the GCC 12.1 patches: https://github.com/srsran/srsRAN/tree/agpl_next

[Ottega]

After changing the branch it compiled without issues. Thank you.
