信号:Ubuntu中PETSc中的分段故障(11)

标签: ubuntu segmentation-fault mpi petsc

我是MPI和PETSc的新人。我在我的系统中安装了PETSc和MPICH2,并尝试运行最简单的Hello World。但是取代预期的输出,会出现很多乱码。

我的make文件是:

ALL:exam_petsc1

CFLAGS          =
FFLAGS          =
CPPFLAGS        =
FPPFLAGS        =
CLEANFILES      = exam_petsc1

include ${PETSC_DIR}/conf/variables
include ${PETSC_DIR}/conf/rules

exam_petsc1: exam_petsc1.o chkopts
    ${CLINKER} -o exam_petsc1 exam_petsc1.o  ${PETSC_LIB}
    ${RM} exam_petsc1.o

我的节目是:

#include <petscksp.h>

int main(int argc, char *argv[])
{
PetscInitialize(&argc,&argv,PETSC_NULL,PETSC_NULL);
PetscPrintf(PETSC_COMM_WORLD,"Hi\n");
PetscFinalize();
return 0;
}
终端中的

“make”没有给出,但是以下

/usr/bin/mpicc -o exam_petsc1.o -c -fPIC -Wall -Wwrite-strings -Wno-strict-aliasing -Wno-unknown-pragmas -g3 -fno-inline -O0 -I/home/soumyadipta/PETSC/petsc-3.3-p1/include -I/home/soumyadipta/PETSC/petsc-3.3-p1/arch-linux2-c-debug/include -I/usr/lib/openmpi/include -I/usr/lib/openmpi/include/openmpi -D__INSDIR__= exam_petsc1.cpp

/bin/rm -f exam_petsc1.o

“mpiexec -np 4 exam_petsc1”提供了一长串错误,如下所示......

我的程序错了???
