Error building QML-Box2D Library

[rognon]

I followed the instructions on the qt wiki page Build-QML-Box2D-Library but get the following compiler error when I try to build in Qt Creator:

C:\Qt\5.4\mingw491_32\include\QtCore\qglobal.h:694: error: invalid application of 'sizeof' to incomplete type 'QStaticAssertFailure<false>'
enum {Q_STATIC_ASSERT_PRIVATE_JOIN(q_static_assert_result, COUNTER) = sizeof(QStaticAssertFailure<!!(Condition)>)}

I am using Qt Creator 3.4.1 (opensource) / Based on Qt 5.4.2 (MSVC 2013, 32 bit) with the MinGW 4.9.1 32 bit compiler.

Full debug output:

Hi and welcome to devnet,

IIRC, the current sources should be fetched from here
