When I attempt to compile a project using boost::interprocess I get compile errors when I include managed_mapped_file.hpp when using VC10. I can create a simple project that is just the following code:
#include
int main(int argc, char* argv[])
{
return 0;
}
When compiling, I get the following errors:
Empty.cpp

[

]
When I look at move.hpp(342) I find the following code:
#if defined(BOOST_MOVE_DOXYGEN_INVOKED)
...unused code...
#else
template <class T> inline
typename remove_reference<T>::type&& move(T&& t)
{ return t; }
#endif
It is complaining about the "return t;" statement. I have just moved up from boost 1.43, where I have been working without problems with VC10.
Is there something I should be doing to prevent this, or is it a bug?
