Ubuntu 12.04 下安裝配置編譯使用OpenCV 2.3.0 全過程

經過幾天的努力，初步完成了對opencv2.3.0的安裝和使用。記錄下過程希望對他人有協助。

首先，的步驟當然是下載和編譯opencv，根據這位大神提供的思路，安裝和編譯還是比較輕鬆。主要有以下幾步：

1、下載opencv解壓opencv

2、進入解壓後的目錄，建立一個目錄用來安放編譯後的檔案，目錄的名字自己取，我去的名字是release

3、不記得哪個版本的opencv之後，編譯前的配置不再用configure檔案了。而改用cmake ，所有趕緊看看自己的系統中是否安裝了cmake 沒有的話，趕緊安裝吧。

4、進去我們剛才建立的目錄中，運行cmake

5、之後就是make && make install 了。

這裡特別提示你需要安裝一個庫，不然在啟動並執行時候你就會發現一個問題

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

問題的原因資訊已經提示了要安裝libgtk2.0-dev and pkg-config,這個不難,鍵入以下的命令就可以了。pkg-config已經在系統中安裝了。

以上幾個步驟對應的命令是

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、這裡就需要看看你的系統中是否安裝了cmake了，如果沒有安裝，就請自行安裝吧命令也很簡單

sudo apt-get install cmake

我一般將安裝和編譯的過程寫在指令碼當中，

3、這裡的/usr/local/opencv是我自訂在系統中安裝的路徑

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