It looks like the program you built has a number of C++ modules. The function names have been mangled, which is what C++ does for overloading. If these functions are to be callable by their "real" names you should consider putting and "extern C" line in your headers where the functions are declared. Something like:
#ifdef __cplusplus
extern "C" {

I am porting another programmers library to the IBMi and attempting to link

I have never built a service program myself before so I'm trying to learn
something new. During the linking stage I get these messages:

Definition supplied multiple times for symbol
Definition supplied multiple times for symbol
Definition supplied multiple times for symbol

Currently in our production code we use *DUPVAR, *DUPPROC, and *NOWARN but
we are really trying to tighten the ship and get our code to compile
cleaner. These symbols appear to come from standard library stuff, I
assume, since they don't look familiar to me. Are there any techniques I
can use to track down the code that generates these symbols then kill and
destroy them? :-)

I am using DSPMOD library/module DETAIL(*EXPORT *IMPORT) via QSH & IFS and
redirecting all of this to a file, so I can search for these symbols and I
know where they exist.

FWIW, I am using the 'icc' compiler that is part of the 5799-PTL package.
It is just a front-end to CRTCPPMOD & CRTPGM. I am also using a makefile &
the 'gmake' command, along with 'ld' and 'qar'.
