在centos7上面安装opencv3.0

1）查版本
gcc --version  需>4.8
Python 2.7+
cmake --version
2）安装cmake
cd /usr/local/src/
wget http://www.cmake.org/files/v3.1/cmake-3.1.3.tar.gz tar -zxvf cmake-3.1.3.tar.gz
cd cmake-3.1.3/
 ./configure
make && make install
cmake --version
3）安装numpy
cd ../
yum install python-devel
wget https://pypi.python.org/packages/source/n/numpy/numpy-1.9.1.tar.gz tar -zxvf numpy-1.9.1.tar.gz
cd numpy-1.9.1/
python setup.py install
python setup.py install
4）安装其他扩展
cd ../
yum install -y gcc gcc-c++ gtk+-devellibjpeg-devel libtiff-devel jasper-devel libpng-devel zlib-devel cmake
yum install Git gtk2-devel pkgconfig numpypython python-pip python-devel gstreamer-plugins-base-devel libv4l ffmpeg-devel(如果未安装上python-pip,安装python-pip可参考http://www.centoscn.com/image-text/install/2015/0816/6013.html)
yum install mplayer mencoder flvtool2(如果未安装上mplayer mencoder ffmpeg，可参考https://my.oschina.net/wen3062/blog/498511,http://jingyan.baidu.com/article/22a299b5cf7ea79e19376ad1.html)
yum install libdc1394
yum install gtk*

#注：有的安装不上的可以下载相应的包解压进行安装
5）安装opencv3.0
wget https://github.com/Itseez/opencv/archive/3.0.0-beta.zip unzip 3.0.0-beta.zip
cd opencv-3.0.0-beta/
mkdir build

make -j8
make install
