如何编译opencv

1. 将OpenCV2.2.0的压缩包解压扮猜到路径D:\OpenCV\opencv （以下所有路径都可自己选择 只要对应起来即可）

2. 安装Cmake，可以模缺漏到官网去下载并按默认设置安装安装即可。

此处注意一般vs采用的是win32编译器进行debug和release（即使你是安装的x64），所以下载cmake的时候应该下载32位版本，这样cmake编译出来旦烂的是32位的工程文件，x64的cmake编译的是64位工程文件。

3.打开Cmake，在第一行“Where is the source code”后面的那个“Browse Source...”按钮，选择OpenCV的安装路径。

运行了楼上给的命令之后，结碧冲果是这样渗销的：

# g++ `pkg-config opencv --libs --cflags opencv` facedect.cpp -o facedect -static

collect2: ld returned 1 exit status

直接编写C 或者C++ 程序，然后分别用gcc，g++编译器生成可执行程序。

1） C++程序版：启轿

#include <stdio.h>

#include <opencv2/opencv.hpp>

using namespace cv

int main(int argc, char** argv )

{

if ( argc != 2 )

{

printf("usage: DisplayImage.out <Image_Path>\悄卜肆n")

return -1

}

Mat image

image = imread( argv[1], 1 )

if ( !image.data )

{

printf("No image data \n")

return -1

}

namedWindow("弊逗Display Image", WINDOW_AUTOSIZE )

imshow("Display Image", image)

waitKey(0)

return 0
