Error building OPNsense 24.7

[om674]

Hi everyone,

I'm trying to build OPNsense 24.7.

As per the documentation at https://github.com/opnsense/tools, I did the following:

# cd /usr
# git clone https://github.com/opnsense/tools
# cd tools
# make update VERSION=24.7
# make dvd VERSION=24.7

gives an error:

It seems like "use of overloaded operator ... is ambiguous" error is not specific to `sort.h`, but occurs everywhere during the build.

I also tried the follwoing, but the same happens.

# cd /usr/src
# make clean
# make buildworld

and

# cd /usr/tools
# make ports

Host OS is fresh install from official `OPNsense-24.7-dvd-amd64.iso` and I have no clue what I am doing wrong.
Any helps very appreciated!
