UPDATE - Building OpenCV-2.4.X for Freescale's i.MX6 BSP (Yocto)

Just updating some information of an old post:  http://imxcv.blogspot.com.br/2014/02/building-opencv-24x-for-freescales-imx6.html

you can base your local.conf on the following one:


 
MACHINE ??= 'imx6qpsabreauto'

DISTRO ?= 'fsl-imx-fb'

PACKAGE_CLASSES ?= "package_rpm"

EXTRA_IMAGE_FEATURES = "debug-tweaks"

USER_CLASSES ?= "buildstats image-mklibs"

PATCHRESOLVE = "noop"

BB_DISKMON_DIRS = "\

    STOPTASKS,${TMPDIR},1G,100K \

    STOPTASKS,${DL_DIR},1G,100K \

    STOPTASKS,${SSTATE_DIR},1G,100K \

    STOPTASKS,/tmp,100M,100K \

    ABORT,${TMPDIR},100M,1K \

    ABORT,${DL_DIR},100M,1K \

    ABORT,${SSTATE_DIR},100M,1K \

    ABORT,/tmp,10M,1K"

PACKAGECONFIG_append_pn-qemu-native = " sdl"

PACKAGECONFIG_append_pn-nativesdk-qemu = " sdl"

ASSUME_PROVIDED += "libsdl-native"

CONF_VERSION = "1"



DL_DIR ?= "${BSPDIR}/downloads/"

ACCEPT_FSL_EULA = "1"



CORE_IMAGE_EXTRA_INSTALL += "libopencv-core-dev libopencv-imgproc-dev libopencv-objdetect-dev libopencv-ml-dev libopencv-calib3d-dev libopencv-highgui-dev"



LICENSE_FLAGS_WHITELIST = "commercial"
that will solve mostly of your issues.

    Hi,

    you don't need to export SDKTARGETSYSROOT , you just need to export ROOTFS_DIR and source the environment-setup script located at your /opt/poky... toolchain folder.

    Dear,
    I am trying to run a simple Camera example using opencv and Yocto.
    I have built Yocto Krogoth for our custom board running i.MX6 and everything is fine. I added the opencv packages as you described in your post and I can see them in the final image.

    Finally, I downloaded your sample application (https://github.com/andreluizeng/opencv-camera-test---i.MX6-Yocto) and tryied to compile it, but I got C++ errors:
    http://pastebin.com/YY9eWBpi

    I edited the Makefile to use the G++ compiler from the SDK generate by Yocto (changing from $(CC) to $(CXX)). I could go further and I am getting a missing header error:
    usr/include/opencv2/core/hal/interface.h:19:19: fatal error: cstddef: No such file or directory

    I could see that Krogoth is enforcing opencv3.1 (2.4 is blacklisted). Could it be an issue?

    Thank you!
