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

安装opencv时ippicv下载超时_压缩包

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
