In short, cmake in the download ippicv_macosx_20141027.tgz this file encountered an error, resulting in the download of the file hash value and expected hash value is different, so we need to download ippicv_macosx_20141027 ourselves. tgz this file and overwrite the past.

If you use Safari to download, you should carefully look at the suffix is not tgz, because the system may be automatically decompressed to tar, so that in the re-encapsulation into tgz, the hash value will change, or not succeed. So you can download it in a different browser, or go to the terminal and use the wget command to download

wget http://www.mirrorservice.org/sites/dl.sourceforge.net/pub/sourceforge/o/op/ Opencvlibrary/3rdparty/ippicv/ippicv_macosx_20141027.tgz

To overwrite the downloaded file to the directory mentioned in the error message, everyone's directory may be different, for example, mine is
/Users/zhaozhaokaliang/opencv-3.0.0/3rdparty/ippicv/downloads/macosx-9662fe0694a67e59491a0dcc82fa26e0/ippicv_macosx_20141027.tgz

(2) If there is no wget in the new Mac, what should I do? Well, that's Ann. How about Ann?

Because software can have dependencies, it is better to use homebrew in order to avoid unnecessary hassles.

And what about the homebrew? That's right, too. All right, let's go.

1: About Homebrew

Homebrew Online version A lot: I used a few are showing 404 Bad Request

Cannot now

There is a URL that gives the latest installation address: the URL is:http://brew.sh/index_zh-cn.html

At the bottom of the website is given the latest in downloading homebrew via terminal:

The most recent path I have downloaded is:

" $ (curl-fssl https://raw.githubusercontent.com/Homebrew/install/master/install) "

Then installing the wget is easy.

Install wget
