Revision history [back]

Hi,

I am on Ubuntu 16.04 (clean install) following this tutorial . Instead of 3.1.0 I tried to install 3.4.6 which did not work, because the Non-free algorithms are not being included. I again tried with version 3.4.4 which again did not work.

Here is a screenshot of the CMAKE output:

The CMAKE command I use:

cmake -D CMAKE_BUILD_TYPE=RELEASE \ 
-D CMAKE_INSTALL_PREFIX=/usr/local \ 
-D INSTALL_PYTHON_EXAMPLES=ON \ 
-D INSTALL_C_EXAMPLES=OFF \ 
-D OPENCV_ENABLE_NONFREE=ON \ 
-D OPENCV_EXTRA_MODULES_PATH=/home/gertjan/opencv_contrib-3.4.4/modules \ 
-D BUILD_EXAMPLES=ON ..

I need the non-free algortihms for the use of SIFT.
