Ubuntu 12.04 下安装配置编译使用OpenCV 2.3.0 全过程

经过几天的努力，初步完成了对opencv2.3.0的安装和使用。记录下过程希望对他人有帮助。

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，

3、这里的/usr/local/opencv是我自定义在系统中安装的路径

sudo cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local/opencv -D BUILD_PYTHON_SUPPORT=ON ..
