ILE C++ is easy to call..thus why we are trying to port it.

C++ in PASE is what is difficult...

That's an interesting statement. If it's an ILE program (or module), why
would it be difficult to call?

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 in
and since there were some existing C++, I thought it'd be worthwhile to
if we could port one over.

You're surprised by this? :-) Not to sound rude or condescending, but
you, like most everyone else in the universe, probably don't do a lot
C++ work on the 400. Unfortunately, we do. We're on V7R3 here. IBM
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
knows why they cannot stay current. I suspect that maybe the OS is
with whatever C++ was in force at the time and so that is what we're
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

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
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
use ILE C/C++...
