我正在使用Boost 1.61并使用clang 4.0.1进行编译，我正在为linux gnu 进行编译
之前我在Boost 1.52上，没有这个问题。仅仅通过更改版本，我就得到了一个关于重新定义mpl_::bool_的编译器错误
我没有使用任何预编译的boost库。这只是标题。
这是我的包括，也是唯一包括的助推：
#include <system/math/math.h>
#include <boost/interprocess/managed_shared_memory.hpp>
#include <boost/interprocess/sync/named_mutex.hpp>
我得到一个编译器错误：

clang正在使用以下参数：-m64 -fdeclspec -Wall -mcx16 -msse4 -stdlib=libstdc++ -g -ggdb3 -O1 -fno-exceptions -std=c++11 -Wextra -DBOOST_DATE_TIME_NO_LIB
发现了类似的错误：https://svn.boost.org/trac10/ticket/12212
注意到我已经为另一个lib定义了这个，所以我取消了它的定义，包括：
#undef BOOST_MPL_CFG_NO_ADL_BARRIER_NAMESPACE
#include <boost/interprocess/managed_shared_memory.hpp>
#define BOOST_MPL_CFG_NO_ADL_BARRIER_NAMESPACE
