Building OpenCV for Python -


i'm using this: http://docs.opencv.org/3.1.0/d7/d9f/tutorial_linux_install.html build opencv on ununtu 16lts python 3. on step 4 in building opencv source using cmake i'm stuck typing in right parameters. you, please check variants, because find folders , no files suggested extensions. also, shall type flag -d before each param?

         -d python3_executable=$home/anaconda3/bin          -d python_include_dir=/usr/include/python3.5          -d python_include_dir2=/usr/include/x86_64-linux-gnu/python3.5m          -d python_library=/usr/lib/x86_64-linux-gnu/libpython3.5m.a          -d python3_numpy_include_dirs= dont have similar path in tutorial, have "numpy" folder in /usr/include/python3.5!    should do?

also, shall write in:

  • -d cmake_install_prefix
  • opencv_extra_modules_path (in tutrial(previus step), o downloaded opencv-contrib. should type in: opencv_extra_modules_path=/home/vladislav/opencv/opencv_contrib
  • build_docs
  • build_examples

error: when run told in tutorial, got mistakes this: cmake error: source directory "/home/vladislav/opencv/build/python_library=/usr/lib/x86_64-linux-gnu/libpython3.5m.so" not exist.

that's example of working cmake params (ubuntu 16.04, latest opencv, python 3.5), need adjust paths own.

cmake -d cmake_build_type=release \             -d python3_executable=/usr/bin/python3.5 \         -d python3_include_dir=/usr/include/python3.5 \      -d python3_library=/usr/lib/python3.5/config-3.5m-x86_64-linux-gnu/libpython3.5.so \     -d python3_numpy_include_dis=/usr/local/lib/python3.5/dist-packages/numpy/core/include \     -d python3_packages_path=/usr/local/lib/python3.5/dist-packages \     -d cmake_install_prefix=/usr/local \     -d opencv_extra_modules_path=../../opencv_contrib/modules \     -d build_examples=on ..

in case opencv_contrib in same folder opencv cmake command starts build folder (mkdir build in opencv folder) in case need jump dirs , important: refer opencv_contrib/modules folder

sometimes it's little bit clearer use cmake-gui

sudo apt install cmake-gui
