Did you notice the file called 'readme.1st'?  It specifically tells you
that when you compile C++ code you must link the C++ libraries, either
by adding '-lgcc' (or -liostr or -lstdcx) to the end of your command
line, or by substituting 'gxx' for 'gcc'.  In RHIDE, if you give your
program a correct C++ filename, it should link the C++ libs
automatically.

This is also a Frequently Asked Question; see chapter 8.7 of the FAQ.
