[Buildroot] [PATCH] zeromq: add C++ bindings

[spdawson at gmail.com]

From: Simon Dawson <spdawson@gmail.com>

Now that zeromq has been bumped to version 3.2.2, we need to provide the
C++ bindings using separate packages. Two C++ bindings are provided by this
patch:

  * cppzmq is a very simple single-header binding
  * zmqpp is a high-level binding, implemented in C++ as a separate library

When the new "C++ bindings" option for zeromq is selected, both of these
C++ bindings are built and installed.

Although only the C binding is bundled with zeromq, the library itself seems 
to be implemented in C++, so this is not correct.

You should probably submit two separate patches for the two separate
packages.

Why don't you make this a normal package?

Not needed.

I really believe cppzmq and zmqpp should be normal separate packages,
that select the zeromq package. I don't see why we would "invert" the
traditional logic we use for all packages.

Same thing for zmqpp.

I'm surprised, you're not passing CC, CXX and al. ? Not needed?

Best regards,

Ah, yes. Thanks for pointing that out. Will fix in the next iteration.

Okay; I'll make them separate packages then.

Hmm. You're quite right --- this doesn't work at all. Will fix in the
next iteration.

Thanks for the feedback.

Doesn't zeromq 3.2.x also require BR2_INET_IPV6, like you posted earlier?

Yes, you're quite right; but this patch has been superseded now.

Simon.
