CMake Error at 3rdparty/tbb/CMakeLists.txt:91 (message): Failed to download TBB sources (1;"Unsupported protocol"): http://www.threadingbuildingblocks.org/sites/default/files/software_releases/source/tbb44_20160128oss_src_0.tgz

Could you please check this out.

that tbb path is "Moved permanently"

Hmm...I can't reproduce this issue here.

http://www.threadingbuildingblocks.org/sites/default/files/software_releases/source/tbb44_20160128oss_src_0.tgz does 301, however the redirect works. As a test, can you fetch the file with this command right?

$ curl -L -o tbb44_20160128oss_src_0.tgz \
    http://www.threadingbuildingblocks.org/sites/default/files/software_releases/source/tbb44_20160128oss_src_0.tgz     

That download runs within cmake, and is unmodified from upstream OpenCV. What's your cmake version? I'm running:

$ cmake --version
cmake version 3.3.2

A console log from running the following commands might help debug too:

$ cd bsp-gonk/
$ source build/envsetup.sh
$ cd external/opencv3
$ mm

[raj2sudha1]

cmake version is 3.5.2

@raj2sudha1 Seems like I just asked you a question on the other issue you filed for the information above. Seems like you are using the correct cmake version. Wondering if you could re-install cmake from https://cmake.org/files/v3.5/ and please try again.

i tried the steps provided here. Still i am getting the above mentioned error. So, i manually downloaded the tbb file and moved to respective folder. the problem solved for the tbb file.

But not facing another issue. -- Downloading v3.1.0/protobuf-cpp-3.1.0.tar.gz... CMake Error at /home/raj/learning/silk/bsp-gonk/external/opencv3/cmake/OpenCVUtils.cmake:1043 (file): file DOWNLOAD HASH mismatch

A hash mismatch like that generally indicates something strange with your network, as you didn't get the right bits for some reason.

Coincidentally,I just made a change that should alleviate the need to download that file though. :) See 4960ff8d65b701997b7c3b6a4d41f12fa0aedc00 for more
