在opencv中文网站下载源码：OpenCV-2.3.0.tar.bz2
在RHEL5中进行解压：
#tar jxvf OpenCV-2.3.0.tar.bz2
#cd OpenCV-2.3.0
未安装cmake需要先安装cmake
#cmake -D BUILD_NEW_PYTHON_SUPPORT=NO .
#make
#make install
#gedit /etc/ld.so.conf.d/opencv.conf
在里面添加/usr/local/lib
#ldconfig
#gedit /etc/bash.bashrc
添加
PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/
local/lib/pkgconfig export
PKG_CONFIG_PATH#cd Opencv2.3.0/sample/c/#chmod +x build_all.sh#./build_all.sh
