Attempting to build latest Lazarus trunk on Linux CentOs7 with Qt5 fails with error:

/home/colla/Applicazioni/lazarus_main/lcl/interfaces//qt5/qtobject.inc:44: undefined reference to `QGuiApplication_setFallbackSessionManagementEnabled'

It succeeds setting

{$DEFINE QT_NO_SESSIONMANAGER}

in qtdefines.inc

My cbindings outdated or bug?

Do not do to others as you would have them do to you.They might have different tastes.

Your bindings are outdated. If you use trunk lazarus then you must build your own bindings. Besides that, bindings won't change soon, so current trunk libQt5Pas v.1.2.13 will be pushed to 2.4 and distros.
