Hi, I'm getting this errors when I try to build on FreeBSD 14.1:

Any hint?

I've tried to reproduce this but not been able to. I'm using FreeBSD 14.2 and Clang 18.1.16 (the version of the base system).

This looks like there might be an issue with the c++ headers. Could you show us the output of:

find /usr/include -name "constexpr_c_functions.h" -o -path "*__string*"

Looking at the path /usr/include/c++ suggests that these headers are expected to be in the base system. One option could be to update the base system in case it has become corrupted for some reason:

sudo freebsd-update fetch
sudo freebsd-update install
