Re: [boost] ABI issues with -std

I solved this in Boost.Log this way:

struct Y { void f( X const& x );

#if !defined(BOOST_NO_CXX11_RVALUE_REFERENCES)

void f( X&& x ) { f_move(x); }

#endif

private: void f_move(X& x); };

Only works if void f( X&& x ) is inlined and even then it still violates ODR doesn't it?

As a slightly different variant of the Boost.System2 solution, I can suggest building multiple Boost.System binaries, one per ABI we can support.

That'd require library name mangling on Linux and adding the std level to the name.. -- Olaf
