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

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

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr -D WITH_IPP=OFF ../opencv-3.0.0-beta（这里把opencv的lib放在了/usr下面）

make -j8

make install
