Question

我准备了一个针对32位Windows的llvm-clang编译器。我使用了3.7.1并应用了this patch。我得到的东西几乎有效，除了我有提升错误。

如果我使用我常用的boost 1.53标头编译我的项目（通常与mingw-gcc一起使用），我遇到麻烦，包括boost/interprocess组件

In file included from [...]/Boost/include-WINDOWS/boost-1_53\boost/interprocess/sync/interprocess_semaphore.hpp:24:
In file included from [...]/Boost/include-WINDOWS/boost-1_53\boost/interprocess/exceptions.hpp:20:

[...]/Boost/include-WINDOWS/boost-1_53\boost/interprocess/detail/win32_api.hpp:878:48: error: conflicting types for 'VirtualProtect'

如果我然后尝试recompile boost：

bootstrap.bat mingw
b2 toolset=clang --with-thread --with-filesystem --with-signals --with-test --with-system --with-regex --with-program_options --with-serialization variant=release link=shared threading=multi

根据各种版本的提升，我收到很多警告，我可以尝试忽略，但也有一些错误：

对于1.56和1.57这些:(不是很多，但我不知道如何摆脱它）

    static const basic_serializer * find(
                                    ^

对于1.59和1.60一堆MMX相关的错误，据我所知，这不是我在准备llvm-clang时可以控制的功能：

在MinGW设置中，有没有办法让任何版本的boost能够在Windows下使用clang 32bit？

我也尝试过llvm 3.8.0，但我无法准备它，因为我的MinGW工具链不支持C ++ 11的某些部分（以及我尝试过的其他版本，请参阅here）。

至于boost.thread：添加-msse（或其他）（解决MMX指令集未启用错误）后，只需将-DBOOST_USE_WINDOWS_H添加到cxxflags，即可解决Windows头文件和boost.date_time中许多系统函数的不同声明。

例如： cxxflags =＆＃34; -msse -DBOOST_USE_WINDOWS_H＆＃34;

在Windows下Mingw + clang vs Boost：不同类型的错误
