gcc

cmake

2.下载下载opencv的安装包opencv-3.1.0.zip

wget  http://nchc.dl.sourceforge.net/project/opencvlibrary/opencv-unix/3.1.0/opencv-3.1.0.zip

可以自己先在网上下载好ippicv_linux_20151201.tgz这个压缩包，然后将其拷贝到下面的文件夹目录：

/usr/local/opencv-3.1.0/3rdparty/ippicv/downloads/linux-808b791a6eac9ed78d32a7666804320e/

然后重新cmake CMakeList.txt

cd /usr/local/opencv-3.1.0

make

如下所示为编译成功

执行

make  install

即可
