PS: võib muuta ka march=native cmake konfifailist, kui tegu on robotile mineva asusega
make -j4 #Kui sul on 4 trheadi/coret
sudo make install
sudo ldconfig


PPS: JPEG=OFF on hea, et kaamerast tuleb stream ei oleks MJPEG.

Kui nutetakse v4lv1 puudumise üle a'la OpenCV-2.2.0/modules/highgui/src/ cap_v4l.cpp:217:28: fatal error: linux/videodev.h: No such file or directory

Siis paigalda v4lv1 dev pakk
<source lang="bash">
<source lang="bash">
sudo apt-get install libv4l-dev
svn co https://robot.itcollege.ee/svn/vision/botmaster2012/

Ja muuta modules/highgui/src/cap_v4l.cpp


rida #include <linux/videodev.h> asendada reaga #include <libv4l1-videodev.h>
