gsettings-qt uses a private symbol

[Timo Jyrinki]

gsettings-qt uses a Qt private symbol _ZN7QObjectC2ER14QObjectPrivatePS_@Base from its libGSettingsQmlPlugin.so library. Could that usage be debugged how it's being used and removed?

The symbol is cause a dependency on qtbase-abi-5-4-0, which means a rebuild is needed when new Qt version like 5.4.1 is uploaded.

< larsu> QObjectPrivate is in a _p.h, but it is marked as Q_CORE_EXPORT and includes a macro named Q_DECLARE_PUBLIC

[Lars Karlitski (larsu)]

I don't know if this is supposed to be a private symbol or not, but it gets pulled in when using the protected constructor of QQmlPropertyMap as documented [1].

I don't think there's anything we can change in gsettings-qt to solve this issue.

As discussed on IRC, the Q_DECLARE_PUBLIC is for different purposes, unrelated to the class publicness.
