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

【中文标题】Windows下的Mingw + clang vs Boost:不同类型的错误【英文标题】:Mingw + clang vs Boost under Windows: different kind of errors 【发布时间】:2016-03-10 15:16:40 【问题描述】: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。我得到了一些几乎可以工作的东西,除了我在提升方面有错误。
如果我使用通常的 boost 1.53 标头编译我的项目(通常与 mingw-gcc 一起使用),我会遇到麻烦,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 与:
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 boost 的不同版本,我会收到很多可以尝试忽略的警告,但也有一些错误:
对于 1.56 和 1.57 就这些:(不多,但我不知道如何摆脱它)

对于 1.59 和 1.60 出现一堆 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:

有没有办法让任何版本的 boost 在 Windows 下在 MinGW 设置中与 clang 32bit 一起使用?
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)。

第二个问题,可能与this patch有关 【参考方案1】:关于 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 标头和 boost.date_time 处许多系统函数的不同声明。
例如: cxxflags="-msse -DBOOST_USE_WINDOWS_H"
