CentOS 6.3中安装OpenCV2.3.1

下面为自己测试可用的OpenCV在Linux(CentOS 6.3)下的安装步骤

1、检查并安装相关程序,确保gtk安装成功,否则无法显示图片

yum install gcc-c++

yuminstall gtk-devel.i686

yum installgimp-devel.i686

yuminstall gimp-devel-tools.i686

yum installgimp-help-browser.i686

yuminstall zlib-devel.i686

yum installlibtiff-devel.i686

yum installlibjpeg-devel.i686

yuminstall libpng-devel.i686

yum installgstreamer-devel.i686

yum installlibavc1394-devel.i686

yuminstall libraw1394-devel.i686

yum installlibdc1394-devel.i686

yum installjasper-devel.i686

yum install jasper-utils.i686

yum installcmake

yum installswig

yum install Python

yum –y install libtool

yum installnasm.i686

2、安装ffmpeg

./configure --enable-shared –disable-yasm

make

make install

此时,ffmpeg默认安装到/usr/local下面

3、安装OpenCV

使用vi打开CMakeLists.txt文件,

(1)找到

set_property( CACHE CMAKE_BUILD_TYPE PROPERTY STRINGS${CMAKE_CONFIGURATION_TYPES} )

后将其注释(添加#号)。

(2)搜索关键字ffmpeg,找到对应位置,修改路径为(这与前面ffmpeg安装路径有关)

if(EXISTS /usr/include/ffmpeg/libavformat/avformat.hOR HAVE_FFMPEG_SWSCALE)

(3)到opencv源代码主目录写下,依次执行

mkdir release

cd release

cmake ../

make

make install

等待安装结束,默认安装到位置/usr/local/。

4、测试

#include <cv.h>
#include <highgui.h>
 
using namespace cv;
int main( int argc, char** argv )
{
  Mat image;
  image = imread(argv[1], 1 );
 
  if( argc != 2 ||!image.data )
    {
      printf("No image data \n" );
      return -1;
    }
  namedWindow("Display Image", CV_WINDOW_AUTOSIZE );
  imshow("Display Image", image );
  waitKey(0);
 
  return 0;
}

编写makefile文件如下,

SRC=DisplayImage.cpp

LIB=-L/usr/local/lib/

INC=-I/usr/local/include/opencv/

Test:$(SRC)

g++ -o Test $(LIB)$(INC) -lopencv_core -lopencv_highgui -lopencv_ml $^ 

执行make,没有错误。继续运行,./Test {ImagePathName},出现不能链接到动态库的错误。

解决办法:

cd /etc/ld.so.conf.d/ (该文件夹下存放了各种动态链接库的路径信息)

新建一个文件,vi usr-lib.conf,添加如下信息(opencv的lib所在路径)

/usr/local/lib

关闭文件后执行ldconfig命令即可。

重新运行,没问题,收工。
