Building 4.1.1 tag on raspberry pi 4 fail (successful with 4.1.0 though) #15495

Closed NicholasJallan closed 5 years ago

NicholasJallan commented 5 years ago
System information (version)
Detailed description

Build is failing without any detail when opencv positionned on tag 4.1.0 and opencv_contrib on tag 4.1.0

… everything fine above
[ 45%] Linking CXX shared library ../../lib/libopencv_imgproc.so
[ 45%] Built target opencv_imgproc
make: *** [Makefile:163: all] Error 2

and you get back to the prompt.

Steps to reproduce

sudo apt-get -y update sudo apt-get -y upgrade sudo apt-get -y install screen sudo apt-get -y install htop

sudo sed -i 's/CONF_SWAPSIZE=100/CONF_SWAPSIZE=2048/g' /etc/dphys-swapfile

sudo /etc/init.d/dphys-swapfile stop sudo /etc/init.d/dphys-swapfile start

sudo sed -i '$a gpu_mem=128' /boot/config.txt

sudo apt-get -y install build-essential cmake pkg-config sudo apt-get -y install libjpeg-dev libtiff-dev libjasper-dev libpng12-dev sudo apt-get -y install libavcodec-dev libavformat-dev libswscale-dev libv4l-dev sudo apt-get -y install libxvidcore-dev libx264-dev sudo apt-get -y install libgtk2.0-dev libgtk-3-dev sudo apt-get -y install libatlas-base-dev gfortran

sudo apt-get -y install python3-dev

cd ~ git clone https://github.com/opencv/opencv.git git clone https://github.com/opencv/opencv_contrib.git cd opencv git checkout 4.1.1 cd ../opencv_contrib git checkout 4.1.1 cd ~

you have to make python3.6 env so it uses python3.6 for the build

mkdir -p .virtualenvs python3 -m venv .virtualenvs/cv2_env source .virtualenvs/cv2_env/bin/activate

took a really long time

pip3 install numpy

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 \ -D ENABLE_NEON=ON \ -D ENABLE_VFPV3=ON \ -D BUILD_TESTS=OFF \ -D OPENCV_ENABLE_NONFREE=ON \ -D INSTALL_PYTHON_EXAMPLES=OFF \ -D BUILD_EXAMPLES=OFF ..

make -j4


At some point, without any other message, you get :

[ 45%] Linking CXX shared library ../../lib/libopencv_imgproc.so [ 45%] Built target opencv_imgproc make: *** [Makefile:163: all] Error 2

I experienced the same thing with 4.1.2 but was able to build 4.1.0 no problem.

This error message is not useful. Try to run make VERBOSE=1.
