You can't put c++ headers that have method overloading inside of an
extern "C" statement.

Yes, the inventor headers need to be put outside of the extern "C"
statement. But your actual native functions that get called (that in
turn call the inventor functions) need to be inside (or their
declaration) the extern 'C" statement.
If you're still having problems, let me know. I've done some stuff
with java->inventor specifically and got it to work.
Hope this makes sense. It was hell trying to get it to work myself.
good luck,
jeff
