do you have an operating system on the 3/80?

what is the error?  without it we can only guess the problem.

I do not believe newlib is supported for SunOS 3 on sun3 hardware.  you
will need to copy libraries and headers from the sun3 to the linux
machine, as well as having a working cross-assembler and linker
(binutils) on the linux machine.

you may find it easier to get a new operating system for your 3/80 which
supports C++ out of the box.  the up-coming release of NetBSD 1.6
(http://www.netbsd.org/) supports C++ as well as cross-compilation of
the base software between NetBSD platforms.
