I'm on Boost 1.61 and compiling with clang 4.0.1 and I'm compiling for linux-gnu
Previously I was on Boost 1.52 and was not having this issue. Just by changing versions, I'm getting a compiler error about redefining mpl_::bool_
I'm not using any precompiled boost libs. This is headers only.
This is my include and the only include of boost:
#include <system/math/math.h>
#include <boost/interprocess/managed_shared_memory.hpp>
#include <boost/interprocess/sync/named_mutex.hpp>
I'm getting a compiler error:

clang is using these args:
-m64 -fdeclspec -Wall -mcx16 -msse4 -stdlib=libstdc++ -g -ggdb3 -O1 -fno-exceptions -std=c++11 -Wextra -DBOOST_DATE_TIME_NO_LIB
Found this which is a similar error: https://svn.boost.org/trac10/ticket/12212
Noticed that I had this defined for another lib, so I undef it for this include:
#undef BOOST_MPL_CFG_NO_ADL_BARRIER_NAMESPACE
#include <boost/interprocess/managed_shared_memory.hpp>
#define BOOST_MPL_CFG_NO_ADL_BARRIER_NAMESPACE
