Hi Frank,
I expect
disconnect callback to be received in two ways as following.
-
When TCP socket is terminated from remote side
-
When keepalive timer expires on Client side
But none of them are helping. No
disconnect callback is received in either of the cases
above.
Attached is my application code
using aync_client. Please help.

Hi Frank,
When running
on ARM, I am facing an issue that disconnect callback is not
being received to application when message broker goes
offline. I am using async_client.
(Note: This
same is not an issue when running on x86, there it works
fine as expected.)
Any known
issue around this ? That can help. I will debug it further
tomorrow and will provide more detail on it.

There should
be no trouble getting it working on an A7 with Yocto. I know
of several people who have incorporated Paho C++ into a Yocto
build, but unfortunately, no one has contributed those builds
back to the project. I hope to do it eventually, but it's not
very high on my list at the moment.

Hi Frank,
Could you
please compile MQTT C++ code base and provide static
library (one lib if possible) for below target platform.
OS:
Digi Embedded Yocto Linux
CPU:
ARM Cortex-A7 @900 MHz
Kernel
Version: Linux ccimx6ulsbc 4.1.41-dey+gf1a146c #2 SMP
PREEMPT Mon Apr 23 10:32:20 EDT 2018 armv7l GNU/Linux
My need
from this library is as following:
-
It should compile/run for Ubuntu X86_64 (required for
development purpose). I have compiled and tested for it
and it works !!!
-
It should also compile/run for embedded environment (as
above). This is where I need help.
Only if it
compiles and runs for embedded environment then only we
can consider this as an option for our production.
Regarding
hiring you for support, I am in discussion with management
and will get back to you.

Pankaj
CMake is now
the preferred method for compiling.
What are you trying with ARM that is failing? Please post
specific error messages. If something appears to be a bug,
please raise an Issue on the GitHub site:
https://github.com/eclipse/paho.mqtt.cpp/issues
That is preferred for specific problems, rather than e-mail
to the group.
Are you compiling natively on an ARM platform, or trying to
cross-compile? If cross, what host? What target?

Hi
Frank,
Today, I
started compiling C++ MQTT source code and was able to
successfully compile and test it for x86 architecture.
(Using Cmake option)
However,
for ARM architecture I am still not successful and need
your help. Can you please help me with the steps on how
to compile it for ARM ?
Also,
please help me with what is the best way from following
options if I am looking to compile it for multiple
platforms (x86, ARM).
Regards
Pankaj
Thanks
Frank.
Appreciate
the quick response !!!

- Can we use it for commercial purpose ?
Yes. The terms of the license are listed on the GitHub
page.

-
Does this library have any third party library
dependency ?
It is a wrapper around the Paho C library.
https://github.com/eclipse/paho.mqtt.c
That library is also required.
-
If we run into issues in future (e.g., memory
corruption within the library), do we get stuck
waiting for the community to fix the issue? Is there
is a commercial support available?
I'm the author, running a software consulting company,
and available for hire. If there is any support that you
require with particular time constraints, you can
contact me directly at this e-mail address.
- Currently, it supports MQTT 3.1.1, what
is the roadmap for supporting MQTT 5.0 ?
MQTT 5.0 and WebSocket support should be complete by the
end of the year.
- Where can I find the list of outstanding
issue, if there are any ?
