I recently tried to use Qt Creator 1.3.2, Qt 4.6.2, and GCC 4.4.0 (32-bit version) on Windows 7 (64-bit) to compile an application using some of the experimental C++0x extensions and encountered the following (fatal) error:
This file requires compiler and library support for the upcoming
ISO C++ standard, C++0x. This support is currently experimental, and must be
enabled with the -std=c++0x or -std=gnu++0x compiler options.
In my search for a solution, I came across the thread qmake and compiler flags?, and added the following to the .pro file:
CXXFLAGS += -std=c++0x
but that didn't seem to make a difference.
So, I expect there's some tag I need to add to the .pro (project) file, but I've never messed with the GCC compiler switches in Qt, QMake, and QtCreator before, and I am uncertain about the proper invokation / incantation. So, my question is how do you set GCC compiler switches when using QtCreator, QMake, and Qt?

It boils down to reading the manual. Instead of using
CXXFLAGS
in the .pro file, you need to useQMAKE_CXXFLAGS
as in:main.cpp:
main.pro:
