guess I am screwed then
That's a bit defeatist, don't ya think?
I had thought wrapping a C++ library (with no C++ experience) was going to be a show-stopper for me too... but after hacking a couple of C libraries (which don't require much glue), it turned out that it wasn't so hard after all.
I ended up using both the tiny documented example in the Blitz help, and browsing through Skid's FLTK glue to give me a guide as to what I could do. (Thanks Skid! :-)
Essentially, I end up with a .cpp file of my own which I use Extern "C" to expose some of my own functions which can call into C++ objects etc.
Of course, you need to know a bit of C/C++, but if you intend wrapping an external library, it's to be expected (I usually learn what I need to know as I go :-p )
I would suggest taking a look at some of the already-wrapped libraries that people have done to point you in the right direction.
