Hi,
I am going to install opencv 3.4 with contrib modules, python3, python3-numpy. But after cmake, I see Python for buils is python2.7. Do I have errors or actually it is ok and I could type make in terminal now?
Beside, I have python2, python3, python2-numpy,python3-numpy on my computer.
Here is the camke command I used: cmake -D CMAKE_BUILD_TYPE=Release \ -D CMAKE_INSTALL_PREFIX=/usr/local \ -D PYTHON3_EXECUTABLE=/usr/bin/python3 \ -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/python3.5/config-3.5m-x86_64-linux-gnu/libpython3.5.so \ -D PYTHON3_NUMPY_INCLUDE_DIRS=/usr/lib/python3/dist-packages/numpy/core/include/ \ -D OPENCV_EXTRA_MODULES_PATH=/home/ics_vr/opencvInstall/opencv_contrib/modules \ -D BUILD_EXAMPLES=ON ..
The general install configuration looks like following:
