Thanks for the help Leo , aparently the missing part was : opencv-staticdev My local.conf ended like : # CONF_VERSION is increased each time build/conf/ changes incompatibly and is used to # track the version of this file when it was generated. This can safely be ignored if # this doesn't mean anything to you. CONF_VERSION = "1" IMAGE_INSTALL_append = " gcc gcc-dev openssh php mariadb opencv opencv-samples" #IMAGE_INSTALL_append = " mpich mpich-dev" IMAGE_INSTALL_append = " libopencv-core-dev libopencv-highgui-dev libopencv-imgproc-dev libopencv-objdetect-dev libopencv-ml-dev opencv-staticdev" LICENSE_FLAGS_WHITELIST = "commercial" IMAGE_FEATURES += "package-management" MACHINE = "intel-corei7-64" I learned in the hard way that CORE_IMAGE_EXTRA_INSTALL and IMAGE_INSTALL_append are nto the same when I build for xfce the CORE_IMAGE_EXTRA_INSTALL is not taking into consideration After that opencv is working like a charm Now I am having problems to come up the web cam , do you know any part that might be missing ? If I do lsusb the webcam is detected( I check and the driver is enable as module in make menuconfig ) , but when I try to run this code , It return as if the camera were not found https://github.com/VictorRodriguez/opencv_tutorial I might be missing gstream or something :( Thanks a lot for the help > >> But got this error : >> >> /usr/lib/gcc/i586-poky-linux/4.9.2/../../../../i586-poky-linux/bin/ld: >> cannot find -lopencv_ts >> collect2: error: ld returned 1 exit status >> >> My local.conf is like this : >> >> EXTRA_IMAGE_FEATURES = "debug-tweaks tools-sdk" >> IMAGE_INSTALL_append = " mpich mpich-dev gcc gcc-dev openssh php mariadb >> opencv" >> LICENSE_FLAGS_WHITELIST = "commercial" >> CORE_IMAGE_EXTRA_INSTALL += "libopencv-core-dev libopencv-highgui-dev >> libopencv-imgproc-dev libopencv-objdetect-dev libopencv-ml-dev" >> >> >> All the help is more than welcome >> >> Best regards >> >> Victor Rodriguez >> > ^ permalink raw reply [flat|nested] 5+ messages in thread
