Boost 1.61 header 正在尝试重新定义 mpl_::bool_

Question

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

之前我使用的是 Boost 1.52，没有遇到这个问题。仅通过更改版本，我收到有关重新定义 mpl_::bool_

的编译器错误

我没有使用任何预编译的增强库。这只是 headers。

这是我的包含，也是唯一的 boost 包含：

#include <system/math/math.h>
#include <boost/interprocess/managed_shared_memory.hpp>
#include <boost/interprocess/sync/named_mutex.hpp>

我遇到编译器错误：

clang 使用这些参数： -m64 -fdeclspec -Wall -mcx16 -msse4 -stdlib=libstdc++ -g -ggdb3 -O1 -fno-exceptions -std=c++11 -Wextra -DBOOST_DATE_TIME_NO_LIB

发现这是一个类似的错误：https://svn.boost.org/trac10/ticket/12212

注意到我已经为另一个库定义了这个，所以我取消定义它包括：

#undef BOOST_MPL_CFG_NO_ADL_BARRIER_NAMESPACE
#include <boost/interprocess/managed_shared_memory.hpp>
#define BOOST_MPL_CFG_NO_ADL_BARRIER_NAMESPACE
