Question

我正在Boost 1.61上并使用clang 4.0.1进行编译，并且正在为linux-gnu进行编译

以前，我使用的是Boost 1.52，没有这个问题。仅通过更改版本，我就收到有关重新定义mpl_::bool_

的编译器错误。

我没有使用任何预编译的boost库。这只是标题。

这是我的包含，也是增强的唯一包含：

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

我遇到了编译器错误：

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

发现了类似错误：https://svn.boost.org/trac10/ticket/12212

注意到我已经为另一个库定义了它，因此我对此没有定义：

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

Boost 1.61标头正在尝试重新定义mpl _ :: bool_
