我的macOS是10.12.4 我已经在我的macbook上安装了PGI(只需通过从PGI官方网站下载的安装程序安装,激活自己的控制台,没有其他操作,在这个控制台中,有像" pgcc pgc ++等命令&# 34;),版本是16.10 我用CLion编辑测试代码:
#include <iostream>
#ifdef _OPENACC
#include <openacc.h>
#endif
using namespace std;
int main() {
#ifdef _OPENACC
//part 1
cout<<acc_get_num_devices(acc_device_not_host)<<endl;
//part2
// const int N = 1024;
// //定义
// int i, a[N], b[N], c[N];
//
// for (i = 0; i < N; i++) {
// c[i] = 0;
// a[i] = b[i] = i;
// }
//
//#pragma acc kernels
// for (i = 0; i < N; i++) {
// c[i] = b[i] + a[i];
// }
// std::cout << c[1] << std::endl;
#else
cout << "not support OpenACC" << endl;
#endif
return 0;
}
当我认罪时,我遇到了一些问题:

并且无论使用pgc ++执行哪个部分(第1部分或第2部分),错误信息可能都是一样的,我不知道在哪里可以开始解决这个问题,我是一个新的macbook ,真的希望得到你的帮助〜
