Qtilities Logging

[Maxxximo]

Hi all,
I'm trying to use the Qtilities logging component in my application.
Everything works fine if I log from the main thread, but if I log from another thread, like:

LOG_TRACE ("Worker::init");

nothing is actually being logged, and I see on the debugger output window:

QObject::connect: Cannot queue arguments of type 'Logger::MessageType'
(Make sure 'Logger::MessageType' is registered using qRegisterMetaType().)

Any hints?

Thanks in advance
Massimo

Hi and welcome to devnet,

I don't know about that library but the error message means your code (or the library) is using a custom type as argument of a SIGNAL/SLOT.

Here you'll find information about that.

You should check with the author(s) of the Library if you're using it in the right way

Thanks for replying, but I already knew that :-)
The library is definitely causing that.
Apparently not so many people are using it, so I might consider using something else if I can't sort this out quickly. Finding a simple and STABLE, thread safe logging library is apparently a difficult task...

We are using Log4Qt. It works pretty well (but you need to apply some code patch to build it with Qt5)
