一维阵列的SSE代码，编译器错误:“无法打开包含文件". [英] SSE codes for 1-D ARRAYS, compiler error: "Cannot open include file".

问题描述

使用MS Visual Studio 2008编译以下代码时，出现

when compiling the codes below using MS Visual Studio 2008, i get

fatal error C1083: Cannot open include file: 'altivec.h': No such file or directory

#include "stdafx.h"
#include <iostream>
#include <altivec.h>
#include <xmmintrin.h>
using namespace std;
int _tmain(int argc, _TCHAR* argv[])
{
    int a[4] __attribute__((aligned(16))) = { 1, 3, 5, 7 };
    int b[4] __attribute__((aligned(16))) = { 2, 4, 6, 8 };
    int c[4] __attribute__((aligned(16)));
    __vector signed int *va = (__vector signed int *) a;
    __vector signed int *vb = (__vector signed int *) b;
    __vector signed int *vc = (__vector signed int *) c;

    *vc = vec_add(*va, *vb);
    printf("c[0]=%d, c[1]=%d, c[2]=%d, c[3]=%d¥n", c[0], c[1], c[2], c[3]);
    return 0;
}

推荐答案

您可以将包含"altivec.h"文件的文件夹添加到VC++目录中:
在Visual Studio上，选择工具->选项菜单项，然后选择 Projects and Solutions-> VC ++目录节点，在显示目录列表中选择包含文件，最后添加适当的文件夹.

BTW使用

You may add the folder containing the "altivec.h" file to the VC++ directories:
On Visual Studio choose the Tools->Options menu item, then select the Projects and Solutions->VC++ Directories node, select the Include files in the Show directories for list and finally add the proper folder.

BTW use

#include "altivec.h"

:)

尝试设置此标头的完整路径
类似于"usr/smart/my_headers/altivec.h"而不是< altivec.h> :)

Try to set the full path to this header
like "usr/smart/my_headers/altivec.h" instead of <altivec.h> :)

除了上述两个答案，还有一件事
如果没有altivec.h文件，则需要从下载该库此处 [ ^ ]

Apart from the above two answers, one more thing
If you don''t have the altivec.h file then you need to download the library from here[^]
