Revision history [back]

Now I have succesfully instaled OpenCV with a extra contrib modules. I had to correctly :

  • Install OpenSSL

  • install Last Release of Libcurl

  • after installing Libcurl I had to recompile last version of CMake with adding parameter to use libcurl in cmake: (in downloaded cmake folder and entered in terminal: sudo ./bootstrap --with-curl -prefix=/usr/local ; sudo make; sudo make install

  • after that I also had to correctly link right libcurl version with instructions here

  • after all theese steps, the last released version of OpenCV 3.4.2 with opencv_contrib-3.4.2 succesfully worked for me ("make -j7" has just one small warning on the start").
