Boost.MPI给出了建筑x86_64的

我试图运行基本"Hello, World!" example未定义的符号：Boost.MPI给出了建筑x86_64的

#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; 
}

我已经试过无数变种运行此程序：

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和clang++作为替代。每个组合给出了如下错误：

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)

家酿说，双方MPICH2和boost1.63.0安装。我可以通过编译，然后运行this program:

// 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 %s\n", numtasks,rank,hostname); 


     // do some work with message passing 


    // done with MPI 
    MPI_Finalize(); 
    }

将会产生正确的输出确认mpic++运行。

我也验证了（至少部分）升压被编译并成功运行安装Boost "Hello, World!"

int main() 
{ 
    boost::asio::io_service io; 

    boost::asio::deadline_timer t(io, boost::posix_time::seconds(5)); 
    t.wait(); 

    std::cout << "Hello, world!" << std::endl; 

    return 0; 
}

有：

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

我怎样才能获得Boost.MPI例子跑步？

当你从boost中得到链接器错误时，你通常忘了链接到boost库。

还有一个boost_mpi库，所以你应该

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

注意，你需要一个升压版本与MPI支持编译。

具体用自制软件可以检查How to build boost with mpi support on homebrew?

似乎我的计算机无法找到它'LD：库找不到-lboost_mpi'。也许Homebrew不会默认安装它或者什么？ – Dair

因此，有一个boost-mpi的酿造公式。我会试试看看它是否有效。 – Dair

是的，似乎是这样，检查http://stackoverflow.com/questions/13143409/how-to-build-boost-with-mpi-support-on-homebrew – overseas
