Help with yocto opencv/openNi

[andreajulian]

hello Im using the wandboard quad now.

previously, we used the wandboard dual;

now i cant bake the same image:

~/fsl-community-bsp$ MACHINE=wandboard-quad . ./setup-environment build

Configuring for wandboard-quad

Welcome to Freescale Community BSP

The Yocto Project has extensive documentation about OE including a

reference manual which can be found at:

    http://yoctoproject.org/documentation

For more information about OpenEmbedded see their website:

    http://www.openembedded.org/

You can now run 'bitbake <target>'

Common targets are:

    core-image-minimal

    meta-toolchain

    meta-toolchain-sdk

    adt-installer

    meta-ide-support

Your configuration files at build has not been touched.

~/fsl-community-bsp/build$ bitbake fsl-image-gui-sdk

Loading cache: 100% |################################################################################################| ETA:  00:00:00

Loaded 1737 entries from dependency cache.

ERROR: Nothing PROVIDES 'fsl-image-gui-sdk'. Close matches:

  fsl-image-gui

  fsl-image-test

Summary: There was 1 ERROR message shown, returning a non-zero exit code.

so i baked the fsl-image-gui, core-image-lsb-sdk, core-image-sato-sdk, and core-image-x11.

now regardless of the image,

i try to install OPENNI

$ cd ~/nfsRootFS/current/home/root

$ sudo wget "http://www.openni.org/wp-content/uploads/2013/11/OpenNI-Linux-Arm-2.2.0.33.tar.zip"

$ sudo apt-get install unzip

$ sudo unzip OpenNI-Linux-Arm-2.2.tar.zip

$ sudo tar xf OpenNI-Linux-Arm-2.2.tar.bz2

$ sudo rm OpenNI-Linux-Arm-2.2.tar.*

$ sudo minicom

# cd ~/OpenNI-Linux-Arm-2.2

root@wandboard-quad:~/OpenNI-Linux-Arm-2.2# ./install.sh

root@wandboard-quad:~/OpenNI-Linux-Arm-2.2# cd Samples/Bin/

root@wandboard-quad:~/OpenNI-Linux-Arm-2.2/Samples/Bin# chmod 777 SimpleRead

root@wandboard-quad:~/OpenNI-Linux-Arm-2.2/Samples/Bin# ./SimpleRead

-sh: ./SimpleRead: No such file or directory

same with opencv

i crossed compiled opencv built all examples as said here: Cross compilation for ARM based Linux systems — OpenCV 2.4.8.0 documentation

root@wandboard-quad:~/opencv-2.4.8/samples/c# ./contours

-sh: ./contours: cannot execute binary file

and if i try a bake:

lighthouse@hec02:~/fsl-community-bsp/build$ bitbake opencv

i have livab installed, and i added the whitelist in the .conf:

LICENSE_FLAGS_WHITELIST = "commercial_libav"

LICENSE_FLAGS_WHITELIST = "commercial"

LICENSE_FLAGS_WHITELIST = "commercial_x264"

ACCEPT_FSL_EULA = ""

what do i do? if these programs don't work, our project won't work.

maybe by adding this?

IMAGE_INSTALL_append = " gcc g++ binutils libgcc libgcc-dev libstdc++ libstdc++-dev libstdc++-staticdev \

tslib-conf tslib-tests tslib-calibrate openssh-sftp-server alsa-lib alsa-tools alsa-state alsa-utils-alsaconf \

tslib evtest dbus nano gstreamer \

cairo pango fontconfig freetype pulseaudio "

im baking another fslimage-gui with this and will update

thanks!

Hi Andrea,

I was able to successfully install OpenCV on yocto, but didn´t try OpenNI yet, I´m going to work on this and let you know soon as I have any result. Also, you can ask the same question on a Yocto forum.

regards,

Andre

[andreajulian]

Thanks Andre!

It worked, but now they tell me this other error shows up. I leave you the

details below:

Ok, I've changed the local.conf and did a bitbake opencv

it worked!

then, i tried to use the smart package manager to add it to the yocto

image....

$ cd ~/fsl-community-bsp/build/tmp/deploy/rpm

$ createrepo --update .

On the board install the new packages

$ sudo minicom

1. smart search opencv

2. smart install opencv

here is my output:

root@wandboard-quad:~# smart search opencv

Updating cache... ########################################

Saving cache...

root@wandboard-quad:~# smart install opencv

Loading cache...

Updating cache... ########################################

error: 'opencv' matches no packages

root@wandboard-quad:~# smart install opencv --stepped

Loading cache...

Updating cache... ########################################

error: 'opencv' matches no packages

and if i try to bake an image (with the parameters given by you in the

local.conf), still cant bake -sdk and now cant do image, will try minimal

and get back

So my question is, do i change back to my original parameters to add

opencv to an image?

thank you for your help....

Hi Andrea,

it is because Yocto will only add the opencv support when you actually build an application that requires OpenCV, otherwise the libraries will not be included. But you can overcome this situation by adding manually the dev packages you want:

in the local.conf you can add:

CORE_IMAGE_EXTRA_INSTALL += "libopencv-core-dev libopencv-highgui-dev libopencv-imgproc-dev libopencv-object-dev libopencv-ml-dev"

and build it with:

bitbake core-image-x11

regards,

Andre

[mahyar1]

Hi Andre,

could you please tell me how did you add opencv libraries to your local config file?

I think packages (recipes) should be available to be added to CORE_IMAGE_EXTRA_INSTALL.

I just have two recipes related to opencv : opencv and opencv-samples (bitbake-layers show-recipes)

so I get an error by running bitbake.

Thanks,

Mahyar

Hi Mahyar,

check this tutorial I made: Computer Vision on i.MX Processors: Building OpenCV-2.4.X for Freescale's i.MX6 BSP (Yocto)

Hi Andrea,

please, use a local.conf like this:

-----------------------

MACHINE ??= 'imx6qsabresd'

DISTRO ?= 'poky'

PACKAGE_CLASSES ?= "package_rpm"

EXTRA_IMAGE_FEATURES = "debug-tweaks"

USER_CLASSES ?= "buildstats image-mklibs image-prelink"

    STOPTASKS,${TMPDIR},1G,100K \

    STOPTASKS,${DL_DIR},1G,100K \

    STOPTASKS,${SSTATE_DIR},1G,100K \

    ABORT,${TMPDIR},100M,1K \

    ABORT,${DL_DIR},100M,1K \

    ABORT,${SSTATE_DIR},100M,1K"

PACKAGECONFIG_pn-qemu-native = "sdl"

ASSUME_PROVIDED += "libsdl-native"

CONF_VERSION = "1"

BB_NUMBER_THREADS = '4'

PARALLEL_MAKE = '-j 4'

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

ACCEPT_FSL_EULA = ""

CORE_IMAGE_EXTRA_INSTALL += "gpu-viv-bin-mx6q gpu-viv-bin-mx6q-devz"

LICENSE_FLAGS_WHITELIST = "commercial"

-----------------------------

I was able to build OpenCV with that, regarding OpenNI, I didn´t find any recipe for this. I will need to investigate how to build it for yocto.

Regards,

Andre
