Does anybody out there know if there is a version of C++ that works on
Silicon Graphics hardware (either the SGI 3000 series, or the 4-D series)??
Is SGI working on a native C++ compiler?
Do any of the independent C++ compiler/interpreter/translator vendors
support the SGI hardware (like AT&T, Oregon, or Oasys/Glockenspiel)??
Any info would be greatly appreciated !!!

We ported the at&t c++ compiler to our iris 3020. no probs. the thing is pretty easily ported to any unix machine. why not buy a copy and port the thing? it is simply a matter of reading the manual and answering some questions as it prompts you (max 1 or 2 days). once cfront is up it uses the c compiler on the iris to generate the executable code. no reason why it should not be simple to port to a 4d.

If you look at the C code that cfront generates, you will see that it pre- and appends extra characters onto your variable names. These names can become very long if a function name in a class is overloaded. For example, I have an overloaded matrix constructor for a 4x4 matrix, and the name generated is something like: _matrix__ctor__D_D_D_D_D_D_D_D_D_D_D_D_D_D_D_D The crappy C compiler that comes with the crappy AT&T Unix only allows variable names to be 32 characters long (at least the one that we have does this). Thus, the compiler blows up, eventually, on code like this. It doesn't complain about "identifier too long" or anything like that - it puts some version of the name in the symbol table, and then blows up when it later tries to match it. Probably one copy is truncated and the other isn't. Since AT&T puts out both C++ and the standard Unix C compiler, you would expect them to be compatible. Maybe this has been fixed in a newer release than what we have - I don't know...I just don't know.

I was writing a compiler in C++ on an SGI Iris a year ago, so I can vouch
that it is feasible. There were a few minor bugs, but we were using an
early version of cfront, not even the latest one available at that time.
I seem to recall that the reason it had not been upgraded was because it
required a fair amount of massaging before installing. I also know that
someone at SGI is or was using C++. Unfortunately, the name escapes me
just now. Definitely someone with a net address, though.
Good luck.
