Hey Peter,
actually we always compiled AtomKraft with a more recent Boost than Nuke's one.
Currently we are using 1.46, statically linked.
When we precompile we use:
-fPIC -O3 -DNDEBUG -DBOOST_DISABLE_ASSERTS
So we do not need -fvisibility=hidden (which btw is gcc only).
AK uses:
date_time
filesystem
program_options
serialization
system
iostreams
thread
Cheers,
P.
