c++ - MPI_Comm_Rank的段错误

Question

我必须处理几年前编写的使用MPI和PETSc的代码。
当我尝试运行它时，函数MPI_Comm_rank()出现错误。
这是代码的开头:

int main(int argc,char **argv)
{
    double mesure_tps2,mesure_tps1;
    struct timeval tv;
    time_t curtime2,curtime1;
    
    char help[] = "Solves linear system with KSP.\n\n";  // NB: Petsc est defini dans "fafemo_Constant_Globales.h"


    std::cout<< "d�but PetscInitialize" <<std::endl;
    (void*) PetscInitialize(&argc,&argv,(char *)0,help);
    std::cout<< "d�but PetscInitialize fait" <<std::endl;

    int world_rank;
    MPI_Comm_rank(MPI_COMM_WORLD, &world_rank);

    PetscFinalize();

}

显然，MPI_Comm_rank()和PetscFinalize()之间有一些代码。
PetscInitialize和PetscFinalize分别调用MPI_INIT和MPI_FINALIZE。
在我的makefil中，我有:

PETSC_DIR=/home/thib/Documents/bibliotheques/petsc-3.13.2
PETSC_ARCH=arch-linux-c-debug
include ${PETSC_DIR}/lib/petsc/conf/variables
include ${PETSC_DIR}/lib/petsc/conf/rules

PETSC36 = -I/home/thib/Documents/bibliotheques/petsc-3.13.2/include -I/home/thib/Documents/bibliotheques/petsc-3.13.2/arch-linux-c-debug/include

Mpi_include=-I/usr/lib/x86_64-linux-gnu/openmpi

#a variable with some files names
fafemo_files = fafemo_CI_CL-def.cc fafemo_Flux.cc fafemo_initialisation_probleme.cc fafemo_FEM_setup.cc fafemo_sorties.cc fafemo_richards_solve.cc element_read_split.cpp point_read_split.cpp read_split_mesh.cpp


PETSC_KSP_LIB_VSOIL=-L/home/thib/Documents/bibliotheques/petsc-3.13.2/  -lpetsc_real -lmpi -lmpi++

fafemo:    ${fafemo_files} fafemo_Richards_Main.o
    g++ ${CXXFLAGS} -g -o fafemo_CD ${fafemo_files} fafemo_Richards_Main.cc ${PETSC_KSP_LIB_VSOIL} $(PETSC36) ${Mpi_include}

使用g++或mpic++似乎没有任何改变。
它可以编译，但是当我尝试执行时，我有:

另外，我的计算机上还有其他MPI程序，但我从未遇到过这样的问题。
有谁知道我为什么要得到这个？

如果有人有同样的问题:
当我安装PETSc时，当我已经在计算机上安装了mpi时，便使用--download-mpich运行了./configure。
为了解决该问题，我做了“rm -rf $ {PETSC_ARCH}”并再次运行./configure。
