C++ 铿锵++；编译简单boost程序链接器命令失败

c++ boost clang

C++ 铿锵++；编译简单boost程序链接器命令失败,c++,boost,clang,C++,Boost,Clang,我一直在关注StackOverflow和其他资源的许多其他答案，但我无法让clang在macOS上使用Boost1.63。简单安装的boost： /bootstrap.sh--前缀=/usr/local /b2 cxflags=“-stdlib=libc++”linkflags=“-stdlib=libc++” 现在。我只是在做以下事情： #include <boost/program_options.hpp> namespace po = boost::program_option

我一直在关注StackOverflow和其他资源的许多其他答案，但我无法让clang在macOS上使用Boost1.63。简单安装的boost：

/bootstrap.sh--前缀=/usr/local

/b2 cxflags=“-stdlib=libc++”linkflags=“-stdlib=libc++”

现在。我只是在做以下事情：

#include <boost/program_options.hpp>
namespace po = boost::program_options;

int main()
{
   // Declare the supported options.
   po::options_description desc("Allowed options");
   desc.add_options()
    ("help", "produce help message")
    ("compression", po::value<int>(), "set compression level")
   ;
}

#包括
名称空间po=boost:：program\u选项；
int main（）
{
//声明支持的选项。
采购订单：选项描述描述（“允许选项”）；
说明添加选项（）
（“帮助”，“生成帮助消息”）
（“压缩”，po:：value（），“设置压缩级别”）
;
}

这给了我：

但是，添加

-l增压系统不起作用。启动boost的解决方案是什么？这条路错了吗？还是我需要其他的旗帜
 我想这是-lboost\u program\u options
。我会被诅咒的。谢谢。我不得不想一想。所以每个选项通常都有一个我需要提供的链接器选项？大多数Boost库都是头库
