mike, thanks!   i found something called nullidentd.  i'll give that a try.

the words "baby" and "bathwater" come to mind!   ;)

reminds me of the good ol days of blue boxing, where you sent routing tones
(multi-frequency) over a POTS line, once you got the attention of a trunk.
normally, MF was OOB (on northern telecom switches, you can sometimes hear MF
when you make toll calls) but still travelled on the same circuits that voice
communication travelled.

the telcos smartened up, and MF is now passed over a completely different
circuit.  for awhile it was possible to call some 800 numbers that routed to
remote places where they didn't convert over to the new separate circuits.

well, i wanted to ask a question that seemed too complicated for email.  i'll
try asking anyway.   :)

i'm getting a g++ error that is confusing the heck out of me:

g++ -g -c -Wall -Woverloaded-virtual  Potential.cc
Potential.cc: In method `void Potential::CalculatePotential(const Run &,
const complex<long double> *)':
Potential.cc:88: argument passing to `complex<long double> *' from `long double'

   typedef complex<long double> cplx;
   void trisolve(const long int , cplx *, cplx *, cplx *, const cplx *, cplx *);

   void Potential::CalculatePotential(const Run &run, const cplx *wf)
      trisolve(run.N, A, B, C, wf, X);   //   <---  line 88

the prototype for trisolve:

run.N is a long int.  everything else is declared a cplx *.  it sounds like
g++ thinks i'm passing a long double when it expects a cplx *.   there are no
long doubles here.

if my understanding of what the error message means is right, then i'm at a
complete loss here.

i know this isn't much to go on.  any suggestions of what to look for?

the idea of templates is great, but i wish the syntax were a bit nicer!
