I would think invoking the executable would be easy. Is it parameter
passing that's the obstacle?
I had issues once with that and ended up loading the parms into
environment variables and the called program just did a GetEnv() to
retrieve.

ILE C++ is easy to call..thus why we are trying to port it.
C++ in PASE is what is difficult...

I've only done a couple of C (not C++) programs on IBM i so I can't
claim
any expertise - just curiosity.

That's an option..
Except I want to call the C++ code from RPG...
And while it appears that can be done, it doesn't appear
particularly simple.

Hi, Charles,
If you really need the latest and greatest C++ standards, you
should be
looking into installing the GCC G++ compiler under PASE. :-)
All the best,

A little yeah, I expected it to be behind...but 9+ years? :o
No, we don't do much C++, none in fact. But I'd really like to
have URI
Templating functionality
https://en.wikipedia.org/wiki/URL_Template
in
RPG
and since there were some existing C++, I thought it'd be
worthwhile to
see
if we could port one over.

you, like most everyone else in the universe, probably don't do
a lot
of
C++ work on the 400. Unfortunately, we do. We're on V7R3
here. IBM
is
not even on C++11, technically, but on C++0x, and you have to,
for
some reason, enable a command option to get that going. Only
God in
Heaven
knows why they cannot stay current. I suspect that maybe the
OS is
written
with whatever C++ was in force at the time and so that is what
we're
stuck
with, but that's only my uneducated guess.
How many lines is this utility? Probably originally written on
a Linux
system with g++?

So we're trying to port a small C++ utility to ILE...
One of the compile errors is on the following...
for(auto& ele : inVars)
Apparently this the "for each" loop which was added to C++ in
2011...(aka
C++11)
We're on v7.2, but even the v7.4 manual doesn't show it as
valid.
Looks like C++ on the IBM i include part of the C+11
standards, but
not
yet
all. And of course C++14 and C++17 are nowhere to be found.
Bit surprised the i is so far behind the times, but I suppose
most
don't
use ILE C/C++...
