Question

我正在尝试在MS VC ++ 2010 express中使用一些图像处理代码。代码使用opencv，所以我已下载并安装它。我创建了一个项目并将opencv文件添加到项目中。我有2个probs，编译器无法打开#include <unistd.h>和#include <getopt.h>。任何想法如何在我的项目中包含这些标题。抱歉，我是c ++的新手，通常在android / eclipse中编程。谢谢！

Answer 1

<unistd.h>是Unix标准头文件，在Windows上找不到。 http://en.wikipedia.org/wiki/Unistd.h

我不知道<getopt.h>。

您的代码似乎是为基于Unix的计算机编写的，而不是Windows。

Answer 2

基于对此源文件的快速浏览，您不需要其中任何一个包含。你绝对不需要getopt，因为你没有使用它定义的getopt函数。只需删除这些包含，然后查看是否有效。

vc ++找不到#include <unistd.h> #include <getopt.h> </getopt.h> </unistd.h>
