1、手动去下载:
github地址为:
https://github.com/opencv/opencv_3rdparty/tree/ippicv/master_20151201/ippicv
2、查看下载tgz压缩包的md5
使用命令
md5sum ippicv_linux_20151201.tgz
3、修改相关makefile
cd /opencv-3.2.0/3rdparty/ippicv/
vi downloader.cmake
将对应的位置的md5更改过来
4、拷贝到相关目录下
将 ippicv_linux_20151201.tgz 拷贝到相应的目录下:
/opencv-3.2.0/3rdparty/ippicv/downloads/linux-d41d8cd98f00b204e9800998ecf8427e
红色部门为md5的值
