【问题描述】：
我正在尝试编译一个在 Ubuntu 18.04 和 Windows 10 上编译没有问题的程序。但是，当我尝试在 OSX High Sierra 上编译它时，我得到了错误，它们仅与 boost 有关。
这是一个例子：
#include <boost/process.hpp>
#include <iostream>
int main()
{
std::cout << "This is a test." << std::endl;
}
然后我尝试使用g++ 和clang 编译程序，如下所示：
g++ -std=c++11 test.cpp -lpthread
然后我得到这个巨大的错误：

我可能缺少编译器标志，我尝试过-lboost_system，但给出了相同的错误。如果这个特定的库与 OSX 不兼容，那么我会尝试找到一个解决方法，但是这个库已经嵌入到我当前正在使用的代码中。
是否有任何已知的解决方法？
【问题讨论】：
-
据我所知，我相信我是。我怎样才能确定？我跑了
grep BOOST_LIB_VERSION /usr/local/include/boost/version.hpp，我回来了#define BOOST_LIB_VERSION "1_69"@CinderBiscuits -
@G.M.我将
#include <csignal>放在boost包含之前，我仍然有同样的错误。我应该在csignal中包含链接器标志吗？ -
试试
clang++ -std=c++11 test.cpp -lpthread -lc++你不应该链接任何特定于boost的东西，因为Boost.Process是一个只有头文件的库，但你需要链接到标准库，它要么是libc++要么是libstdc++ . （分别为-lc++和-lstdc++。） -
@CinderBiscuits 尝试了推荐的标志，但我仍然得到同样的错误。我什至重新安装了 boost，以确保我安装了 1.69.0。
