some problems:
1.-- ICV: Downloading ippicv_linux_20141027.tgz... CMake Error at 3rdparty/ippicv/downloader.cmake:71 (file): file DOWNLOAD HASH mismatch for file: [/home/jason/program/opencv-3.0.0/3rdparty/ippicv/downloads/linux-8b449a536a2157bcad08a2b9f266828b/ippicv_linux_20141027.tgz] expected hash: [8b449a536a2157bcad08a2b9f266828b] actual hash: [0103b909e19ca9c6497a7ae696c16480]
solution:ippicv_linux_20141027.tgz的校验值不符，从http://sourceforge.net/projects/opencvlibrary/files/3rdparty/ippicv网站下载ippicv_linux_20141027.tgz放到/usr/local/opencv-3.0.0/3rdparty/ippicv/downloads/linux-8b449a536a2157bcad08a2b9f266828b/下替换原ippicv_linux_20141027.tgz
