对VS 2013和Cygwin使用fork（） [英] Using fork() with VS 2013 and Cygwin

问题描述

我想写一个C程序，将在Visual Studio 2013中使用fork（）和wait（）。我已经下载并安装Cygwin，但我无法配置Visual Studio使用适当的头文件。我对IDE很新，我想知道这个社区是否可以帮我找出我在犯错误的地方。

I am trying to write a C program that will use fork() and wait() in Visual Studio 2013. I have downloaded and installed Cygwin, but I am unable to configure Visual Studio to use the appropriate header files. I'm fairly new to the IDE and I was wondering if this community could help me figure out where I am making a mistake.

当开始一个新项目时，我做什么：

When starting a new project, this is what I do:

1. 创建新的Visual C ++ Win32控制台应用程序


2. 添加新的main.c源文件到项目


3. 右键单击项目属性并将包含目录配置为
   ，包括Cygwin目录：C：\cygwin64

我已经截图了我想要配置的属性，如果这是我在犯错误：

I've taken a screenshot of where I am trying to configure the properties in case this is where I am making my mistake:

我的代码很简单，因为我只是想让它运行在这个point：

My code is rather simple as I am just trying to get it to run at this point:

#include <unistd.h> 

int main() {
    int i;
    i = fork();

    if (i == 0) {
        printf("I am the child.");
    }
    else {
        wait(&i);
    }
}

这是我收到的错误消息的屏幕截图尝试建立我的项目：

Here's a screenshot of the error message I receive when I try to build my project:

如果这是一个愚蠢的问题，我提前道歉，但我很感激你可以提供任何帮助。

I apologize in advance if this is a silly question, but I do appreciate any help that you can offer. If there is anything that I can do on my end to help troubleshoot, please let me know.

推荐答案

问题是，您的当前包含路径 C：\cygwin64\bin 等效于unix / bin 可执行文件）。要使用unix头，您需要使用等效的 / usr / include ，对于您的系统，应该是 C：\cygwin64\\ \\ usr \include 。

The problem is that your current include path C:\cygwin64\bin is equivalent to unix /bin, which is for binaries (aka executables). To use unix headers, you need to use the equivalent of /usr/include, which, for your system, should be C:\cygwin64\usr\include.
