如何从boost获得平台ID? [英] How to get platform IDs from boost?

问题描述

我们怎么知道代码正在运行哪个操作系统?

例如如何知道Unix-Linux，Solaris，HP Unix，Windows，Mac等操作系统?

我们如何通过Boost确定C ++代码中的操作系统?我想从Boost v1.41开始测试.

解决方案

以下是对 version.hpp / config.hpp 的快速扫描:>

在Coliru上直播

  #include< boost/version.hpp>#include< boost/config.hpp>#include< iostream>int main(){std :: cout<<"BOOST_VERSION"<<BOOST_VERSION<<"\ n";std :: cout<<"BOOST_LIB_VERSION"<<BOOST_LIB_VERSION<<"\ n";std :: cout<<"BOOST_PLATFORM"<<BOOST_PLATFORM<<"\ n";std :: cout<<"BOOST_PLATFORM_CONFIG"<<BOOST_PLATFORM_CONFIG<<"\ n";std :: cout<<"BOOST_COMPILER"<<BOOST_COMPILER<<"\ n";#ifdef BOOST_LIBSTDCXX_VERSIONstd :: cout<<"BOOST_LIBSTDCXX_VERSION"<<BOOST_LIBSTDCXX_VERSION<<"\ n";#万一#ifdef BOOST_LIBSTDCXX11std :: cout<<已启用c ++ 11支持编译\ n";#万一std :: cout<<"BOOST_STDLIB"<<BOOST_STDLIB<<"\ n";std :: cout<<"BOOST_STDLIB_CONFIG"<<BOOST_STDLIB_CONFIG<<"\ n";}

或者在我自己的机器上

  BOOST_VERSION 106500BOOST_LIB_VERSION 1_65BOOST_PLATFORM LinuxBOOST_PLATFORM_CONFIG boost/config/platform/linux.hppBOOST_COMPILER GNU C ++版本7.2.0BOOST_LIBSTDCXX_VERSION 70200编译时启用了c ++ 11支持BOOST_STDLIB GNU libstdc ++版本20170818BOOST_STDLIB_CONFIG boost/config/stdlib/libstdcpp3.hpp 

How can we know which operating system the code is running?

e.g. How to know the operating system like Unix-Linux, Solaris, HP Unix, Windows, Mac etc?

How can we determine operating system in C++ code with boost? I want to test with Boost v1.41 onwards.

解决方案

These are things a quick scan of version.hpp/config.hpp revealed:

Live On Coliru

#include <boost/version.hpp>
#include <boost/config.hpp>
#include <iostream>

int main() {
    std::cout << "BOOST_VERSION           " << BOOST_VERSION           << "\n";
    std::cout << "BOOST_LIB_VERSION       " << BOOST_LIB_VERSION       << "\n";
    std::cout << "BOOST_PLATFORM          " << BOOST_PLATFORM          << "\n";
    std::cout << "BOOST_PLATFORM_CONFIG   " << BOOST_PLATFORM_CONFIG   << "\n";
    std::cout << "BOOST_COMPILER          " << BOOST_COMPILER          << "\n";
    #ifdef BOOST_LIBSTDCXX_VERSION
    std::cout << "BOOST_LIBSTDCXX_VERSION " << BOOST_LIBSTDCXX_VERSION << "\n";
    #endif
    #ifdef BOOST_LIBSTDCXX11
    std::cout << "Compiled with c++11 support enabled\n";
    #endif
    std::cout << "BOOST_STDLIB            " << BOOST_STDLIB            << "\n";
    std::cout << "BOOST_STDLIB_CONFIG     " << BOOST_STDLIB_CONFIG     << "\n";
}

Which prints

BOOST_VERSION           106400
BOOST_LIB_VERSION       1_64
BOOST_PLATFORM          linux
BOOST_PLATFORM_CONFIG   boost/config/platform/linux.hpp
BOOST_COMPILER          Clang version 3.8.0 (tags/RELEASE_380/final 263969)
BOOST_STDLIB            libc++ version 1101
BOOST_STDLIB_CONFIG     boost/config/stdlib/libcpp.hpp

Or on my own machine

BOOST_VERSION           106500
BOOST_LIB_VERSION       1_65
BOOST_PLATFORM          linux
BOOST_PLATFORM_CONFIG   boost/config/platform/linux.hpp
BOOST_COMPILER          GNU C++ version 7.2.0
BOOST_LIBSTDCXX_VERSION 70200
Compiled with c++11 support enabled
BOOST_STDLIB            GNU libstdc++ version 20170818
BOOST_STDLIB_CONFIG     boost/config/stdlib/libstdcpp3.hpp
