Hi and welcome to devnet,
That's because you try to access a standard member variable from a static function.
Take a look at the ir_receiver example of the pigpio project. It shows how to use a class with the callback with gpioSetAlertFuncEx.

Did you try the this https://bugreports.qt.io/browse/QTBUG-62216
For the pi2 configuration the change should be something like this:
-QMAKE_LIBS_EGL = -lEGL -lGLESv2
-QMAKE_LIBS_OPENVG = -lEGL -lOpenVG -lGLESv2
+QMAKE_LIBS_EGL = -lbrcmEGL -lbrcmGLESv2
+QMAKE_LIBS_OPENGL_ES2 = -lbrcmEGL -lbrcmGLESv2
+QMAKE_LIBS_OPENVG = -lbrcmEGL -lbrcmOpenVG -lbrcmGLESv2
@Xenoshell What's the full output from the configure? Or more specifically, what is the output from the tests that are built to test for gstreamer and dbus?
That will help shed some light on your install issue. It sounds like even though you installed all the *-dev packages Qt isn't finding them properly.
Can you share the settings of your serial port?
Are you sure about them ? Is Flow Control enabled?
Ok, I've missed that article.
From the looks of it, you seem to be currently essentially interested in building qtbase, so you could call configure directly in it to shorten the list of options.
Intuitively, I'd avoid the reduce-exports and sysroot parameters.
@moldovan.catalin You can create symbolic link in /opt/vc/lib pointing to these libraries but having old names.
Solved the Issue for me.
What are you doing in the processing part ?
Then I'd recommend taking a look the example code and rewrite yours to match it.
