Question

我正在尝试使用gcc在C语言中编译MSMPI程序。

这就是我要包含在代码中的内容：

#define MSMPI_NO_SAL

#include "mpi.h"
#include <stdio.h>
#include <stdlib.h>
#include <time.h>

我正在使用Vscode执行以下任务：

{
  "version": "2.0.0",
  "tasks": [{
    "type": "shell",
    "label": "C/C++: gcc.exe build active file",
    "command": "C:\\MinGW\\bin\\gcc.exe",
    "args": ["-g", "${file}","-I","C:\\Program Files (x86)\\Microsoft SDKs\\MPI\\Lib\\x64","-I","C:\\Program Files (x86)\\Microsoft SDKs\\MPI\\Include",  "-o", "${fileDirname}\\${fileBasenameNoExtension}.exe"],
    "options": {
      "cwd": "${workspaceFolder}"
    },
    "problemMatcher": ["$gcc"],
    "group": {
      "kind": "build",
      "isDefault": true
    }
  }]
}

但是，在尝试编译时，我的代码收到以下错误：

In file included from d:\Documents\1.Ecole\University\Undergrad\Fall 2020\COMP 428\ass1\pi_est_parallel.c:5:

我忘了在编译时包含一些内容吗？

这是Microsoft <select id="test_1"> <option value="0.1">dolor</option> <option value="a">sit</option> <option value="-1">Lorem</option> <option value="0">ipsum</option> <option value="A">amet</option> </select> <ul id="test_2"> <li>z</li> <li>-20</li> <li>ab</li> <li>100</li> <li>1</li> <li>00</li> <li>10</li> <li>Ab</li> <li>0.1</li> </ul> <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>头文件中的一个已知问题：

Build errors with MSMPI_NO_SAL

该问题引用了simple patch adding _Out_writes_来解决此问题。您可以通过添加

在自己的代码中进行镜像

mpi.h

在添加#define _Out_writes_(x)之前，如果您不能升级到最新版本。

无法使用MSMPI和GCC编译程序
