ubuntu12.04配置qt4+opencv2.4.1环境

参考文章：

首先安装g++

hugo@hugo-ThinkPad-Edge:~$ sudo apt-get install g++

hugo@hugo-ThinkPad-Edge:~$ sudo apt-get install g++ automake

安装qt4相关

hugo@hugo-ThinkPad-Edge:~$ sudo apt-get install libqt4-dev qt4-dev-tools qt4-designer qt4-doc qt4-demos

安装qt4 creator

下载地址： http://qt-project.org/downloads/
下载后是run文件，修改权限并运行，然后图形化界面安装

hugo@hugo-ThinkPad-Edge:~/Downloads$ sudo chmod 777 qt-creator-opensource-linux-x86_64-3.0.1.run

配置opencv环境

首先更新和升级系统

hugo@hugo-ThinkPad-Edge:~$ sudo apt-get update

hugo@hugo-ThinkPad-Edge:~$ sudo apt-get upgrade

安装必要的依赖环境

sudo apt-get install build-essential libgtk2.0-dev libjpeg-dev libtiff4-dev libjasper-dev libopenexr-dev cmake python-dev python-numpy python-tk libtbb-dev libeigen2-dev yasm libfaac-dev libopencore-amrnb-dev libopencore-amrwb-dev libtheora-dev libvorbis-dev libxvidcore-dev libx264-dev libqt4-dev libqt4-opengl-dev sphinx-common texlive-latex-extra libv4l-dev libdc1394-22-dev libavcodec-dev libavformat-dev libswscale-dev

下载、编译、运行opencv2.4.1（不建议2.4.8，我配置2.4.8后出现问题）

hugo@hugo-ThinkPad-Edge:~/Downloads$ wget http://downloads.sourceforge.net/project/opencvlibrary/opencv-unix/2.4.1/OpenCV-2.4.1.tar.bz2

hugo@hugo-ThinkPad-Edge:~/Downloads$ tar jxvf OpenCV-2.4.1.tar.bz2

hugo@hugo-ThinkPad-Edge:~/Downloads$ cd OpenCV-2.4.1

hugo@hugo-ThinkPad-Edge:~/Downloads/Opencv-2.4.1$ mkdir build

hugo@hugo-ThinkPad-Edge:~/Downloads/Opencv-2.4.1$ cd build

hugo@hugo-ThinkPad-Edge:~/Downloads/OpenCV-2.4.1/build$  cmake -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_QT=ON -D WITH_OPENGL=ON ..

hugo@hugo-ThinkPad-Edge:~/Downloads/OpenCV-2.4.1/build$ make

hugo@hugo-ThinkPad-Edge:~/Downloads/OpenCV-2.4.1/build$ sudo make install

编辑环境变量

hugo@hugo-ThinkPad-Edge:~/Downloads/OpenCV-2.4.1/build$ sudo vim /etc/ld.so.conf.d/opencv.conf

添加opencv库所在路径：

/usr/local/lib

hugo@hugo-ThinkPad-Edge:~/Downloads/OpenCV-2.4.1/build$ sudo ldconfig

hugo@hugo-ThinkPad-Edge:~/Downloads/OpenCV-2.4.1/build$ sudo vim /etc/bash.bashrc

在末尾添加：

PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig
export PKG_CONFIG_PATH

至此，配置成功。
