boost.mpi给出了架构x86_64的未定义符号

我正在尝试运行基本的"你好，世界！"示例：

#include <boost/mpi/environment.hpp>
#include <boost/mpi/communicator.hpp>
#include <iostream>
namespace mpi = boost::mpi;
int main()
{
  mpi::environment env;
  mpi::communicator world;
  std::cout << "I am process " << world.rank() << " of " << world.size()
            << "." << std::endl;
  return 0;
}

我尝试了许多用于运行此程序的变体：

mpic++ -I /usr/local/include/ test.cpp -o test -lboost_system

也：

mpic++ -I /usr/local/include/boost test.cpp -o test -lboost_system

并使用mpicc，而clang++作为替代品。每种组合都会给出以下错误：

Undefined symbols for architecture x86_64:
  "boost::mpi::environment::environment(bool)", referenced from:
      _main in test-b0215f.o
  "boost::mpi::environment::~environment()", referenced from:
      _main in test-b0215f.o
  "boost::mpi::communicator::communicator()", referenced from:
      _main in test-b0215f.o
  "boost::mpi::communicator::rank() const", referenced from:
      _main in test-b0215f.o
  "boost::mpi::communicator::size() const", referenced from:
      _main in test-b0215f.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Homebrew说MPICH2和BOOST1.63.0都安装了。我可以确认mpic++通过编译然后运行此程序运行：

   // required MPI include file  
   #include "mpi.h"
   #include <stdio.h>
   int main(int argc, char *argv[]) {
   int  numtasks, rank, len, rc; 
   char hostname[MPI_MAX_PROCESSOR_NAME];
   // initialize MPI  
   MPI_Init(&argc,&argv);
   // get number of tasks 
   MPI_Comm_size(MPI_COMM_WORLD,&numtasks);
   // get my rank  
   MPI_Comm_rank(MPI_COMM_WORLD,&rank);
   // this one is obvious  
   MPI_Get_processor_name(hostname, &len);
   printf ("Number of tasks= %d My rank= %d Running on %sn", numtasks,rank,hostname);

        // do some work with message passing 

   // done with MPI  
   MPI_Finalize();
   }

产生正确的输出。

我还验证了（至少一部分）Boost是通过编译和成功运行Boost" Hello，World！"

clang++ -I /usr/local/include/ timer.cpp -o timer -lboost_system

如何获得boost.mpi示例运行？
