内联调用always_inline'__m256d _mm256_broadcast_sd(const double *)'失败 [英] inlining failed in call to always_inline '__m256d _mm256_broadcast_sd(const double*)'

问题描述

我正在尝试运行由我的一个朋友创建的Visual Studio cpp项目.我正在尝试在没有VS的情况下运行文件.但是我得到了所有相同格式的错误列表:

I'm trying to run a Visual Studio cpp project created by a friend of mine. I'm trying to run the file without VS. But I'm getting a list of errors, all in the same format:

inlining failed in call to always_inline '__m256d _mm256_broadcast_sd(const double*)': target specific option mismatch|

它在带有释放模式的VS中正常运行，并且在调试模式下运行时中断.

It runs correctly in VS with release mode and breaks when run in debug mode.

include如下:

#include "stdafx.h"
#include <iostream>
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include <vector>
# include <omp.h>
#include <chrono>
#include <fstream>
#include <algorithm>

#include <immintrin.h>

using namespace std::chrono;
using namespace std;

，然后从这里调用该错误:

and the error is called from here:

double zero = 0;
__m256d acc = _mm256_broadcast_sd(&zero);

更新:

我正在使用以下命令来运行它:g++ -std=c++0x multip.cpp -o multip，是否还有其他参数可将-mavx添加到编译器调用中?

I'm using the this command to run it: g++ -std=c++0x multip.cpp -o multip, is there an additional parameter to add -mavx to the compiler invocation?

推荐答案

特定于目标的选项不匹配" 意味着您在GCC调用中缺少功能标记.您可能需要在编译器调用中添加-mavx.

"Target specific option mismatch" means that you're missing a feature flag from your GCC invocation. You probably need to add -mavx to your compiler invocation.

如果仅打算在计算机上运行此功能，则-march=native将打开您自己的计算机支持的所有功能标志.

If you're intending to run this on your computer only, -march=native will turn on all the feature flags that your own machine supports.
