VS与MinGW编译器有啥不同

Posted 2023-02-19

参考技术A vs
倾向于依赖很多windows特有的库，mingw多数只依赖于ms
c运行库
vs
2013前对c++11支持的不好，mingw使用gcc/g++做编译器，对c++11支持的较好
效率方面

一般更快谢谢

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

【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:
In file included from [...]/Boost/include-WINDOWS/boost-1_53\boost/interprocess/errors.hpp:37:
[...]/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）

In file included from libs\serialization\src\xml_wiarchive.cpp:35:
.\boost/archive/impl/archive_serializer_map.ipp:41:34: error: redeclaration of 'boost::archive::detail::archive_serializer_map::insert' cannot add 'dllexport' attribute

    static const basic_serializer * find(
                                    ^

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）。

【问题讨论】：

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"
