首先，的步骤当然是下载和编译opencv，根据这位大神提供的思路，安装和编译还是比较轻松。主要有以下几步：
1、下载opencv解压opencv
2、进入解压后的目录，建立一个目录用来安放编译后的文件，目录的名字自己取，我去的名字是release
3、不记得哪个版本的opencv之后，编译前的配置不再用configure文件了。而改用cmake ，所有赶紧看看自己的系统中是否安装了cmake 没有的话，赶紧安装吧。
4、进去我们刚才创建的目录中，运行cmake
5、之后就是make && make install 了。
这里特别提示你需要安装一个库，不然在运行的时候你就会发现一个问题
OpenCV Error: Unspecified error (The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Carbon support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script) in cvNamedWindow, file /home/bush/OpencvSrc/OpenCV-2.3.0/modules/highgui/src/window.cpp, line 275
terminate called after throwing an instance of 'cv::Exception'
what(): /home/bush/OpencvSrc/OpenCV-2.3.0/modules/highgui/src/window.cpp:275: error: (-2) The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Carbon support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script in function cvNamedWindow
问题的原因信息已经提示了要安装libgtk2.0-dev and pkg-config,这个不难,键入以下的命令就可以了。pkg-config已经在系统中安装了。
以上几个步骤对应的命令是
1、
wget http://nchc.dl.sourceforge.net/project/opencvlibrary/opencv-unix/2.3/OpenCV-2.3.0.tar.bz2
tar -xvf OpenCV-2.3.0.tar.bz2
2、
cd OpenCV-2.3.0
sudo mkdir relese
cd relese
sudo apt-get install libgtk2.0-dev
3、这里就需要看看你的系统中是否安装了cmake了，如果没有安装，就请自行安装吧命令也很简单
sudo apt-get install cmake
我一般将安装和编译的过程写在脚本当中，[code]#########################################################################

sudo cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local/opencv -D BUILD_PYTHON_SUPPORT=ON ..
4、配置后自然就是make 和make install 了
sudo make
sudo make install
当然你可以选择脚本的方法来安装，[code]#######################################################################

fi[/code]这里，opencv的安装算是完成了，不过要怎么用它编译我自己的源代码呢？
需要做一些配置工作了。需要做如下的几步工作
1.添加库路径
sudo vim /etc/ld.so.conf.d/opencv.conf
/usr/local//opencv/lib(添加内容)
2.更新系统库
$sudo ldconfig
3.设置环境变量
export PKG_CONFIG_PATH=/usr/local/opencv/lib/pkgconfig:$PKG_CONFIG_PATH 你也可以选择脚本，
这里说明几点：1、使用>> 可以在文件的最后累加文字。2、touch可以用来创建一个0字节的文件。3、grep -x 可以用来严格匹配文件中的数据。4、file 命令用来查看文件是否存在。（这里需要做完系统环境的配置后，重新打开一个命令行。关闭原来的命令行）
好了现在opencv的系统环境配置好了，那么我们怎么编译呢？当然用g++ ,不过我觉得输入一大堆命令太麻烦，索性写了个makefile 文件，[code]OBJS= test.o
CC=g++
INCLUDE= -I/usr/local/opencv/include -I/usr/local/opencv/include/opencv -I/home/bush/prj/linuxchuankou/include
LIB= -L /usr/local/opencv/lib `pkg-config --libs opencv`
Test:$(OBJS)
$(CC) -o Test $(OBJS) $(LIB)
test.o:test.cpp
$(CC) -c -g test.cpp $(INCLUDE)
clean:
-rm Test $(OBJS)
#`pkg-config --libs opencv` -I/usr/local/OpenCV-2.4.2/build/include/opencv2-lopencv_highgui -lopencv_core[/code]这是我的测试源码[code]/*************************************************************************

cvReleaseImage(&img);

}[/code]在命令行中键入make 就可以编译完成了哈。
以上就是opencv2.3.0的编译安装和使用过程，希望对你有帮助哦。
