Re: Swarm and C++ model

[glen e. p. ropella]

It should be doable today with XPCOM (which is a part of Mozilla).  I, 
personally,
haven't done it; but, if you search the swarm-support archives, you'll see 
several
messages back and forth between Daniel Kottow and Marcus Daniels.  The
thread starts in December of 2001.

If, however, you simply want to run c++ from ObjC, and your c++ code is
fairly self-reliant, *and* you don't mind compiling both your ObjC and your c++
with the same compiler, then you can just declare your c++ interface functions
as "extern" in a header file made available to your objc classes and call
them directly.

The only trick is to use the right version of the compiler (g++ for the linking
but include -lobjc) and call the c++ with the munged names.  You can find
the munged names by calling "g++ -S -c xyz.cc".
