First specify the version number and the number of CPU cores
export OPENCV_VERSION=4.6.0
export NUM_JOBS=8
download and unzip
wget -O https://github.com/opencv/opencv/archive/${OPENCV_VERSION}.zip && \
unzip opencv.zip && \
cd opencv-${OPENCV_VERSION} && \
mkdir -p build && cd build
compile and install
cmake -DCMAKE_BUILD_TYPE=Release -DOPENCV_GENERATE_PKGCONFIG=YES -DWITH_GTK=ON -DBUILD_TFF=ON -DWITH_EIGEN=OFF -DENABLE_PRECOMPILED_HEADERS=OFF -DCMAKE_INSTALL_PREFIX=/usr/local/opencv4.6.0 ..
sudo make install -j${NUM_JOBS}
potential problem
…/…/lib/libopencv_imgcodecs.so.5.0.0: undefined reference to `TIFFReadRGBAStrip@LIBTIFF_4.0’
cmake选项中加上:BUILD_TIFF=ON
Removed the so file of libtiff in anconda
sudo rm /home/ztyf/anconda3/lib/libtiff.so*
Resolving libpangoft2-1.0.so.0: undefined reference to 'pango_font_get_hb_font'
locate libpangoft2-1.0.so.0
选择/usr/lib/x86_64-linux-gnu/libpangoft2-1.0.so.0,将其拷贝到报错的路径完全解决。
Compile opencv cuda version under Ubuntu //lib/x86_64-linux-gnu/libblkid.so.1 undefined 'uuid_unparse@UUID_1.0'
sudo rm /home/xing/anaconda3/lib/libuuid.so.1
sudo ln -s /lib/i386-linux-gnu/libuuid.so.1 /home/xing/anaconda3/lib/libuuid.so.1
之后重新cmake; sudo make -j8; sudo make install;
