Can't build CDP 8 because of POS64 in dev/newsfsys/sfsys.c Any hotfix possible?

pkg upgrade
pkg install git build-essential cmake dos2unix libandroid-glob portaudio-static

# edited in any way on the UNIX-like operating system

# make a local fork in which all code is tracked in

# these are the patches which can fix your actual errors.
# the changes involve workarounds for several GNU-isms and
# Windows-isms written by the upstream developer, who is
# understandably likely focused on Windows and might not have
# the resources to maintain support for alternative UNIX-like operating systems.
