不能从“boost：：interprocess：：mapped_region”转换为“boost：：interprocess：：mapped_region&”

Question

当我试图编译一个简单的boost应用程序时

#include <boost/interprocess/allocators/allocator.hpp>
#include <boost/interprocess/managed_shared_memory.hpp>

在和2010中，我得到了这个错误消息。

c:\program files\boost\boost_1_44_0\boost\interprocess\detail\move.hpp(342): error C2440: 'return' : cannot convert from 'boost::interprocess::mapped_region' to 'boost::interprocess::mapped_region &&'

========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

我不明白是什么问题。我删除了所有的函数实现，只有c_tor和d_tor，但是仍然有相同的错误。

您可以围绕这一点工作，如这里所示。它看起来像是Boost或编译器在处理rvalue引用时的一个限制。

#define BOOST_NO_RVALUE_REFERENCES成功了。谢谢。
