VS2019配置OpenMP

新建Cpp文件，输入以下代码

#include <cstdio>
#include <omp.h>

int main(int argc, char *argv[]) {
    int nthreads, tid;
/* Fork a team of threads with each thread having a private tid variable */
#pragma omp parallel private(tid)
    {
        /*Obtain and print thread id*/
        tid = omp_get_thread_num();
        printf("Hello World from thread = %d\n", tid);
        /* Only master thread does this */
        if (tid == 0) {
            nthreads = omp_get_num_threads();
            printf("Number of threads = %d\n", nthreads);
        }
    }/*All threads join master thread and terminate */
    return 0;
}

运行后会报错或与预料输出不符

右键项目名，打开属性面板，调整以下配置

调整后再次运行即可
