It's the same problem, everything has to be built/linked/dynamically loaded
with the same c++ library. So unless you have the complete source to
Performer (which you can feel free to give me a copy of ;-) ), you are
forced to use the sgi compiler on sgi machines. This has always been a
disadvantage when using c++ libraries for cross-platform development I
believe (and of course the advantage of java). And I thought I heard awhile
ago that there was a way in g++ to set the name-mangling scheme to match
sgi's. But that's probably a rumor and probably not advised anyways. Anyone
know anything about that?
If you really really want to use g++ libraries with sgi performer, you could
take the desparate measure of first compiling your function under sgi c++
and looking at how the function gets name mangled (using nm), and then
compiling the function in g++ wrapping the function with extern "C" and
using the name-mangled name that sgi c++ uses. I've never tried it but I
think in theory it should work (but again probably not advisable for
everyday use)
