I'm trying to compile the Jni code (from
https://gerrit.iotivity.org/gerrit/#/c/7895/) on Darwin and I've hit a
brick wall. I don't know C++/Boost thoroughly enough to see what's going on
here:

So the problem seems to be a typing incompatibility in the use of
apply_visitor in JniOcRepresentation. That's about as far as I can get.
Any suggestions?
