OpenCV yocto

[Victor Rodriguez]

HI team

I am having this same problem:

http://stackoverflow.com/questions/25332969/opencv-pkg-config-cannot-find-lopencv-ts-when-compiling-using-g

I try to build opencv simple source code :

g++ hello.cpp -o video `pkg-config --cflags --libs opencv`

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

Victor, you may take at look at this recipe (opencv_samples)

http://cgit.openembedded.org/cgit.cgi/meta-openembedded/tree/meta-oe/recipes-support/opencv/opencv-samples_2.4.bb?h=master

What I can see, seems that the `pkg-config --libs openvc` is missing on 
your bb.

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

I might be missing gstream or something :(

Thanks a lot for the help
