#include <cv.h> #include <highgui.h> #include "/home/amina/src/openrobots/include/opencv2/imgproc/imgproc.hpp" #include "/home/amina/src/openrobots/include/opencv2/objdetect/objdetect.hpp" #include "/home/amina/src/openrobots/include/opencv2/highgui/highgui.hpp" #include "/home/amina/src/openrobots/include/opencv2/core/core.hpp"

I solved the problem and I want share the answer with you. I installed OpenCV 2.4.2 manually, the prefix installation was /usr/local/ Genom ( the tool I use) installed another version automatically, that was version 2.4.1 and the prefix was /home/amina/src/openrobots My variables PKG_CONFIG_PATH and LD_LIBRARY_PATH included both prefexies and I was passing genom prefix to ./configure when creating makefiles: all that created a conflict when linking. Now, I modified my environment variables to keep only one link to one version of the library, the one that genom installed.
