failing build opencv and opencv_contrib on Jetson TX2

edit

I'm trying to install OpenKAI on TX2, and install opencv like this : `git clone https://github.com/opencv/opencv.git

git clone https://github.com/opencv/opencv_cont...

cd ~/opencv

mkdir build

cd build

cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local -D OPENCV_EXTRA_MODULES_PATH=../opencv_contrib/modules ..

make -j3

sudo make install`

But I failed 'make -j3' with output and error shown like this: Error log: Build output check failed: Regex: 'command line option .* is valid for .* but not for C++' Output line: 'cc1plus: warning: command line option ‘-Wmissing-prototypes’ is valid for C/ObjC but not for C++' Compilation failed: source file: '/home/apsync/GitHub/opencv/build/CMakeFiles/CMakeTmp/src.cxx' check option: ' -fsigned-char -W -Wall -Werror=return-type -Werror=non-virtual-dtor -Werror=address -Werror=sequence-point -Wformat -Werror=format-security -Wmissing-declarations -Wmissing-prototypes' ===== BUILD LOG ===== Change Dir: /home/apsync/GitHub/opencv/build/CMakeFiles/CMakeTmp
