Fedora12配置OpenCV开发环境

///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////?
//源码安装cmake
1.下载cmake源码cmake-2.6.2.tar.gz，http://www.cmake.org/cmake/resources/software.html?
2.编译安

tar xvf cmake-2.6.2.tar.gz
cd cmake-2.6.2/
//如果本机上不存在cmake，则：
./bootstrap
make
make install
//如果本机上存在cmake，想安装一个新版本，则：
cmake .
make
make install

///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////?
//源码安装opencv?
1.下载opencv，http://www.opencv.org.cn/index.php/Download
2.安装opencv-2.3.0

tar -xvf OpenCV-2.3.0.tar.bz2
cd OpenCV-2.3.0/
mkdir release
cd release
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D BUILD_PYTHON_SUPPORT=ON ..
make
sudo make intall

3.添加库路径

//编译执行第一个C实现的OpenCV程序

//OpenCV参考手册：http://www.opencv.org.cn/index.php

1.程序代码show.c

?

#include "cv.h"
#include "highgui.h"

int main(int argc, char **argv)
{
    IplImage* pImage;
if(argc==2 && (pImage=cvLoadImage(argv[1],1))!=0)
    {
        cvNamedWindow("Image",1);
        cvShowImage("Image",pImage);
        cvWaitKey(0);
        cvDestroyWindow("Image");
        cvReleaseImage(&pImage);
return 0;
    }
return -1;
}

2.编译代码

[kang@Gala opencv]$ gcc show.c -o show
show..c:1:16: error: cv.h: No such file or directory
show..c:2:21: error: highgui.h: No such file or directory
show..c: In function ‘main’:
show..c:6: error: ‘IplImage’ undeclared (first use in this function)
show..c:6: error: (Each undeclared identifier is reported only once
show..c:6: error: for each function it appears in.)
show..c:6: error: ‘pImage’ undeclared (first use in this function)
show..c:7: error: subscripted value is neither array nor pointer

由于highgui中采用了C++，所以一定要用g++编译才可以，编译命令如下：

?

import sys
import cv

if __name__ == '__main__':
    image=cv.LoadImage("1.jpg")
    cv.NamedWindow("mywin")
    cv.ShowImage("mywin",image)
    cv.WaitKey(0)

2.执行程序show.py

?

[kang@Gala opencv]$ sudo cp /usr/local/lib/python2.6/dist-packages/cv.so /usr/lib/python2.6/site-packages
