[Updated with minimal reproducing example] Mac OS X 10.9: can't compile a project with Qt 5.2 beta

Violet Giraffe

I'm trying to check Qt 5.2 to see if OS X 10.9-specific bugs have been fixed, but can't build my project. I have C++11 disabled (no CONFIG+=C++11), but I use some older C++0x features so I have -std=c++0x.

The problem is that for some reason C++11-specific defines get defined somewhere (in the mkspec?), and since I don't have C++11 support it fails to compile. Any ideas on how to fix it without enabling C++11?

Actually, even with CONFIG+=C++11 and QMAKE_CXXFLAGS+=-std=c++11 I get a lot of weird errors (not with ‘initializer_list, though, that seems to have solved). Is mkspec broken in Qt 5.2 on 10.9?

Disregard my previous message, there might have been a mess with compiler flags. Let's return to the initial problem with initializer_list. Steps to reproduce:

Install "Qt 5.2 beta for Mac OS X":http://download.qt-project.org/development_releases/qt/5.2/5.2.0-beta1/
Create a new console application project with Qt Creator using Qt 5.2 kit.
Add QMAKE_CXXFLAGS+=-std=c++0x to the project file. My project looks like this:

@QT += core

TARGET = Test
CONFIG += console
CONFIG -= app_bundle

TEMPLATE = app

QMAKE_CXXFLAGS+=-std=c++0x

SOURCES += main.cpp
@

main.cpp:

@#include <QList>

int main(int, char *[])
{
return 0;
}@

Attempt to compile, it will fail. Output:

@In file included from ../Test/main.cpp:1:
In file included from ../Qt5.2.0/5.2.0-beta1/clang_64/lib/QtCore.framework/Versions/5/Headers/QList:1:

I had some problem, it solved by adding
@CONFIG += c++11@
instead of
@CONFIG += C++11@
