[Boost-users] statechart XCode 4.5 compilation error

Hi. The following source code does not compile in XCode 4.5 (it is developer preview 2 version at this moment). I've got answer from one of the apple guys: "It's a known issue that when using libc++ in C++11 mode, instantiating std::list causes instantiation of the element type more aggressively than other std::list implementations. This probably won't be fixed for Xcode 4.5." Source code: #include <functional> #include <iostream> #include #include class InitialState; class StateMachine : public boost::statechart::state_machine { public: StateMachine() { } }; class InitialState : public boost::statechart::simple_state { public: InitialState() { } }; int main(int argc, char const* argv[]) { std::cout << "Hello, World!\n"; StateMachine s; return 0; } Errors: In file included from /Users/developer/Downloads/Sandbox/Sandbox/main.cpp:12: In file included from /usr/local/boost_1_50_0/boost/statechart/state.hpp:11: In file included from /usr/local/boost_1_50_0/boost/statechart/simple_state.hpp:13: /usr/local/boost_1_50_0/boost/statechart/detail/leaf_state.hpp:26:27: error: base class has incomplete type class leaf_state : public state_base< Allocator, RttiPolicy > ~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /Developer4/Xcode45-DP2.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../lib/c++/v1/type_traits:1889:54: note: in instantiation of template class 'boost::statechart::detail::leaf_state' requested here decltype(_VSTD::move(_Tp(_VSTD::declval<_Args>()...)), true_type()) ^ /Developer4/Xcode45-DP2.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../lib/c++/v1/type_traits:1890:1: note: while substituting deduced template arguments into function template '__is_constructible_test' [with _Tp = std::__1::allocator>, void *>>, _Args = <no value>] __is_constructible_test(_Tp&&, _Args&& ...);

*** So, it looks like it became boost's problem. Any help? WBR, Anton.
