<![CDATA[QtMqtt module installation and linking problem]]>Hi,

I try to install and compile qmqtt from its git repo. It was worked. But somehow now its giving below error.

It is compiling but when I run :

dyld: Library not loaded: @rpath/QtMqtt.framework/Versions/5/QtMqtt
  Referenced from: /Users/opop/Projects/build-qtmqtt-GCC_Release-Release/examples/mqtt/subscriptions/mqttsubscriptions.app/Contents/MacOS/mqttsubscriptions
  Reason: image not found
The program has unexpectedly finished.

What am I missing ? I am working at Mac os X sierra.

Sometime Qtcreator look very complex after java world :=

thanks

Can we use qmqt from another thread ?

What branche did you build ?

According to our past experience we faced problems with mongo to write data from distance (connection lost , network error etc) so we used rabbitMQ, amqp . and mqtt. they are very reliable to send data.

So we want to send pure png data to remote mqtt: such as:

data: time, text, id , png(binary)

Thx

mqtt was designed for IOT devices to easy broadcast ( publish ) data to other nodes.
http://mqtt.org/
So it would not be my first choice for large heavy binary data but we send 100 MB xml across a lan connection and it was ok fast but not realtime at all.
Also, the focus is on many to many connections via the broker so if you do not need say one node send an image, many nodes must see it. Then the mqtt protocol might not have much to offer you besides easy setup and operation.

LIBS +=-L/usr/local/Cellar/qt/5.10.0_1/lib

One more question:

Is the qtmqtt is a good way to send binary data ie: 80K images which captured by camera (object detection)?

https://github.com/qt/qtmqtt

Where did you clone the repository from ? There are several non-official mqtt modules that exists.
