I want to install OpenCV V4.5.2 from source, so I cloned the repo and the contrib repo from github, checked out to that tag: 4.5.2 and tried to install OpenCV with these flags:
cmake -D CMAKE_BUILD_TYPE=RELEASE \-D CMAKE_INSTALL_PREFIX=/usr/local \-D WITH_CUDA=ON -D WITH_CUBLAS=ON \-D WITH_TBB=ON -D WITH_V4L=ON \-D WITH_QT=OFF -D WITH_OPENGL=ON \-D BUILD_PERF_TESTS=OFF \-D BUILD_opencv_cudacodec=OFF \-D OPENCV_EXTRA_MODULES_PATH=../../opencv_contrib/modules \-D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON\-D OPENCV_ENABLE_NONFREE=ON -D BUILD_NEW_PYTHON_SUPPORT=ON \-D BUILD_opencv_python3=ON -D HAVE_opencv_python3=ON\-D PYTHON_DEFAULT_EXECUTABLE=/usr/bin/python3 \-D CUDA_TOOLKIT_ROOT_DIR=/usr/local/cuda ..I have CUDA 11.4 installed, I checked that using nvidia-smi and nvcc -V, and compiling OpenCV make -j10 works, but when I try to install it after sudo make install I get this error:
