Unable to download ippicv_linux_20151201.tgz
I believe this is a similar problem to #41 (closed) . The error shows up as a hash mismatch, but really the file wasn't downloaded. I extracted the URL and downloaded manually through a browser, put it in the expected directory, and re-ran make. It then gets past this point successfully. I'm running Linux Fedora 21.
