I have a Pi running a fresh Arch Linux installation and I want to install OpenCV 3, but I am facing an error that I do not have when installing OpenCV on my other computers. I wrote a script that works on my other Arch computers, 'opencv' installed by pacman is just OpenCV 2 but I want 3:
#!/bin/bash
# Install opencv with extras and contrib from git
# Tested on ArchLinux
HOME_DIR=/home/counter
# Go to home dir
cd $HOME_DIR
# Install all needed dependencies
sudo pacman -S opencv pkg-config gtkglext intel-tbb libdc1394 openexr xine-lib eigen python-numpy python2-numpy cmake mesa mesa-libgl gstreamer gstreamer0.10-base gst-plugins-base-libs v4l-utils ffmpeg protobuf git wget curl
# Install optional dependencies
sudo pacman -S libcl # For coding with OpenCL
sudo ldconfig
# Download all needed files
# It's always slow on first time but when interrupted and started again it's much faster
git clone https://github.com/Itseez/opencv.git
git clone https://github.com/Itseez/opencv_contrib.git
git clone https://github.com/Itseez/opencv_extra.git
# Start building
cd $HOME_DIR/opencv
mkdir build
cd $HOME_DIR/opencv/build
cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local -D OPENCV_EXTRA_MODULES_PATH=$HOME_DIR/opencv_contrib/modules $HOME_DIR/opencv/build -D OPENCV_TEST_DATA_PATH=$HOME_DIR/opencv_extra -D BUILD_opencv_highgui=OFF -D BUILD_PYTHON_SUPPORT=ON -D BUILD_EXAMPLES=ON ..
# -D BUILD_opencv_dnn=OFF on errors with libprotobuf
make -j5
# Install them
echo "Install OpenCV"
sudo make install
sudo ldconfig
But when running cmake there occurs an error:
cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local -D OPENCV_EXTRA_MODULES_PATH=$HOME_DIR/opencv_contrib/modules $HOME_DIR/opencv/build -D OPENCV_TEST_DATA_PATH=$HOME_DIR/opencv_extra -D BUILD_opencv_highgui=OFF -D BUILD_PYTHON_SUPPORT=ON -D BUILD_EXAMPLES=ON ..

All examples on how to install OpenCV for the Pi do not set any flag that they run on a Pi and I guess I have installed all dependencies, I do not want to create sym links between libraries to make it work.
Edit: I can install a working opencv with yaourt but not opencv-contrib
