我在我的一个项目中使用 Boost.Log v2，并且在构建它时收到以下警告：

C:\boost-1.55\include\boost\log\utility\setup\common_attributes.hpp:22: In file included from C:\boost-1.55\include/boost/log/utility/setup/common_attributes.hpp:22:0,
PROJECT_PATH\PROJECT_NAME\main.cpp:12: from ..\PROJECT_NAME\main.cpp:12:
C:\boost-1.55\include\boost\log\attributes\counter.hpp:-1: In instantiation of 'boost::log::v2_mt_nt5::attribute_value boost::log::v2_mt_nt5::attributes::counter<T>::impl_generic::get_value() [with T = unsigned int]':
PROJECT_PATH\PROJECT_NAME\main.cpp:44: required from here
C:\boost-1.55\include\boost\log\attributes\counter.hpp:133: avertissement : address requested for 'next', which is declared 'register' [-Wextra]
     return make_attribute_value(next);
                                     ^

我想删除这个警告，因为我无法修复它，因为它是 Boost 库的一部分。但是，我没有找到任何-Wno-xxx删除它的选项（-Wno-extra不起作用）。我正在使用 GCC 4.8.2。

我怎样才能抑制这个警告？

包含 boost 库时，您可以禁用警告

#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wextra" // address requested for 'next', which is declared 'register'

//#include "boost/header_you_want.h"

#pragma GCC diagnostic pop
