MPI "hello world"编译失败

Question

今天我尝试编译经典的MPI“hello world”程序

#include <stdio.h>
#include <mpi.h>

int main(int argc, char** argv)
{
    MPI_Init(&argc, &argv);

    int rank;
    int size;

    MPI_Comm_rank(MPI_COMM_WORLD,&rank);
    MPI_Comm_size(MPI_COMM_WORLD,&size);

    printf("I am rank %d of %d\n", rank, size);

    MPI_Finalize();

    return 0;
}

为此，我安装了 openMPI、lam、lam-devel(用于 mpicc)。我尝试遵循 this old thread adressing this problem 中给出的答案，这会导致安装 automake、autoconf、libtool 以及 here我也是来安装coreutils的。不幸的是，当我尝试编译上面的代码时，我仍然收到以下错误消息

mpicc hello.c   -o hello
gcc: error: libtool:: Datei oder Verzeichnis nicht gefunden
gcc: error: link:: Datei oder Verzeichnis nicht gefunden
mpicc: No such file or directory

请求编译器版本给出

mpicc --version
gcc (SUSE Linux) 4.8.5

你可以试试 mpic++ 吗:

mpic++ hello.c   -o hello

它正在我的机器上运行

我使用了openmpi:

sudo apt-get install openmpi-bin
