我試圖讓一些圖像處理代碼在MS VC++ 2010 express中工作。代碼使用opencv，所以我已經下載並安裝了它。我創建了一個項目並將opencv文件添加到項目中。我有2個probs編譯器無法打開#include <unistd.h>和#include <getopt.h>。任何想法如何將這些標題包含在我的項目中。對不起，但我是新來的C + +通常編程在android/eclipse。謝謝！vC++無法找到#include <unistd.h> #include <getopt.h>
#include <cv.h>
#include <highgui.h>
#include <math.h>
