我无法使用C++编译MPI编译器

Question

我试图编译一个非常简单的MPI hello_world:

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

int main(int argc, char *argv[]) {
    int numprocs, rank, namelen;
    char processor_name[MPI_MAX_PROCESSOR_NAME];

    MPI_Init(&argc, &argv);
    MPI_Comm_size(MPI_COMM_WORLD, &numprocs);
    MPI_Comm_rank(MPI_COMM_WORLD, &rank);
    MPI_Get_processor_name(processor_name, &namelen);

    printf("Process %d on %s out of %d\n", rank, processor_name, numprocs);

    MPI_Finalize();
}

并得到以下问题:

    Catastrophic error: could not set locale "" to allow processing of multibyte characters

我真的不知道该怎么弄清楚.

Answer 1

尝试定义环境变量

LANG=en_US.utf8
LC_ALL=en_US.utf8

假设你在UNIX上,也尽量man locale和locale -a在命令行,谷歌的"UTF区域"以及类似的搜索.
