Sven is right. From qcompilerdetection.h:
# if (defined(Q_CC_CLANG) || defined(Q_CC_INTEL)) && defined(Q_OS_MAC) &&
defined(__GNUC_LIBSTD__) \
&& ((__GNUC_LIBSTD__-0) * 100 + __GNUC_LIBSTD_MINOR__-0 <= 402)
// Apple has not updated libstdc++ since 2007, which means it does not have
// <initializer_list> or std::move. Let's disable these features
# undef Q_COMPILER_INITIALIZER_LISTS
# undef Q_COMPILER_RVALUE_REFS
# undef Q_COMPILER_REF_QUALIFIERS
// Also disable <atomic>, since it's clearly not there
# undef Q_COMPILER_ATOMICS
# endif
In other words: stop using libstdc++ on OS X.
