ubild error on linux with Qt 4.8.2

[gambr]

Hi All,
I moved from qt 4.7.2 to Qt 4.8.2 and I have to say just building Qt on linux was not straightforward: I had to modify a file (https://bugreports.qt-project.org/browse/QTBUG-23364) and build with some specific options (i.e. -no-xshape).

Now building my app I get the following error:

In file included from 3rd_party/qt/qt-4.8.2/include/QtCore/qobject.h:1,

3rd_party/qt/qt-4.8.2/include/QtCore/../../src/corelib/kernel/qobject.h:94: error: expected `;' before "static"

Can anybody explain me please the reason?
