macOS Linking with Qt and Boost under MacOS X

[shuras]

Hi there!
I am quite a newbie on Mac platform and trying to port my code working under Windows and Linux to Yosemite.
I use QtCreator (with Clang) as an IDE and Boost from brew for regex operations. Everything compile fine but linking produce errors for symbols like this:
boost::re_detail:: perl_matcher<__gnu_cxx::__normal_iterator<char const*, std::string>, std::allocator<boost::sub_match<__gnu_cxx::__normal_iterator<char const*, std::string> > >, boost::regex_traits<char, boost::cpp_regex_traits<char> > >::construct_init(boost::basic_regex<char, boost::regex_traits<char, boost::cpp_regex_traits<char> > > const&, boost::regex_constants::_match_flags)

I checked contents of Boost library and didn't see any symbols with __normal_iterator in place.
Looks like brew's Boost compiled with _wrap_iter instead of __normal_iterator.
I suspect what it is just a matter of different compilers or C++ specs used but doesn't know much about MacOS environment. My system's g++ currently linked to Clang. I suppose it is possible to use GNU compiler instead and different possibility for std lib too.
Can anyone recommend a way out from this situation? Any clue?

Qt and boost are nice framework and easy to use under mac.
qmake is also an easy way to generate from a qt project (.pro) a Makefile or a Xcode project.

the standard gcc/g++ from Apple development tools (4.2.1!!!) is very old. It was a release from 2007... Lots of modern things are missing such as c++11.

Either you compile a new gcc/g++ or you use clang with c++11.

The easiest is to recompile boost like that:
./bootstrap.sh --prefix=/usr/local
sudo ./b2 toolset=clang cxxflags="-std=c++11 -stdlib=libc++" linkflags="-stdlib=libc++" -j 12 --prefix=/usr/local --build-dir=/Volumes/Develop/BuildMac/boost_1_59_0 release install

then compile you project in the ide of your choose with clang and stdlib=libc++ and std=c++11

Done.

Thank you for your answer.
CXXFLAGS="-std=c++11 -stdlib=libc++"
This is all I've been needed inside my qt project.
