<![CDATA[How can I use the QtMqtt code?]]>Re: How can I use the QtMqtt code?
Hi, I'm trying to use the qtmqtt library, but I can't make it work.
I modified the source code as said in the referenced topic (deleting all <QtMqtt/ prefixes), but I obtained this:

It says that, i.e.,
'class QList<QMqttTopicName>' has no member named 'resize'; did you mean 'size'?
m_receiveAliases.resize(m_clientPrivate->m_serverConnectionProperties.maximumTopicAlias());
^~~~~~
size

Can you help me? I'm using Qt 5.15.0
Thanks!

You have to change the branch and not download the default one. Select the correct qt version and not the master branch!

You may want to look at step #16 from this guide

I'm a starter. Could you please explain to me how you managed to solve this issue? I get the same errors and I think I downloaded the wrong repo after reading your answer.
Thanks in advance.

For all who read this topic, please be careful on which repo do you download. You have to change the branch and not download the default one. Select the correct qt version and not the master branch!

@jsulm said in How can I use the QtMqtt code?:

@pabloleibo The error messages are not related to QtMqtt.
QList does not have resize() method.
And QStringView does not have method split().

Yes, I don't know why!
