1.下載 OpenCV-2.3.1a.tar.bz2

http://sourceforge.net/projects/opencvlibrary/files/opencv-unix/2.3.1/

?

2. 解壓

tar -jxvf OpenCV-2.3.1a.tar.bz2 -C extract path

3 編譯 安裝

cmake?-D?CMAKE_BUILD_TYPE=RELEASE?-D?CMAKE_INSTALL_PREFIX=/usr/local sourcecode/path

得到 makefile

sudo make install

等待。。。。。。

4. 編譯例子

//p_w_picpath_name.c

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

int main( int argc, char** argv )
{
???

??????? IplImage* img;
??????? if( argc == 2 && (img = cvLoadImage( argv[1], 1)) != 0 )
??????? {
???????????

??????????????? cvNamedWindow( "Image view", 1 );
??????????????? cvShowImage( "Image view", img );
??????????????? cvWaitKey(0); // 非常重要，內部包含事件處理循環
??????????????? cvDestroyWindow( "Image view" );
??????????????? cvReleaseImage( &img );
??????????????? return 0;
?????????????????

??? }
??????? return -1;
???????????

}
