OpenCV libraries missing after build is successful

OpenCV libraries missing after build is successful

Hi all,

I appended OpenCV and Gstreamer plugins to Image and made a build. Build is
successful without any errors but OpenCV libraries are missing in
rootfs.tar.bz2

I searched for libs( libopencv_core.so, libhighgui.so, libOpenCV.so ) in
/usr/bin, /usr/lib and the whole archive but unable to find any libraries.

In /yocto/build/downloads, I can
see OpenCV-2.4.3.tar.bz2, OpenCV-2.4.3.tar.bz2.done files.

In /yocto/build/tmp/deploy/licenses, I can see OpenCV folder.

In /yocto/build/tmp/deploy/rpm/armv7a_vfp_neon, I can see .rpm packages.

Log file after build says this:
(Pasted only start and success logs)

NOTE: recipe opencv-2.4.3-r2: task do_compile: Succeeded
NOTE: recipe opencv-2.4.3-r2: task do_install: Started

NOTE: recipe opencv-2.4.3-r2: task do_populate_lic: Succeeded

Any Idea/hints where these files are and why they are missing?

Regards,

The top-level package 'opencv' is empty.  All the bits are in other
packages, e.g. on my system I have:
   # opkg list-installed | grep opencv
   libopencv-calib3d2.4 - 2.4.3-r2
   libopencv-contrib2.4 - 2.4.3-r2
   libopencv-core2.4 - 2.4.3-r2
   libopencv-features2d2.4 - 2.4.3-r2
   libopencv-flann2.4 - 2.4.3-r2
   libopencv-highgui2.4 - 2.4.3-r2
   libopencv-imgproc2.4 - 2.4.3-r2
   libopencv-legacy2.4 - 2.4.3-r2
   libopencv-ml2.4 - 2.4.3-r2
   libopencv-nonfree2.4 - 2.4.3-r2
   libopencv-objdetect2.4 - 2.4.3-r2
   libopencv-photo2.4 - 2.4.3-r2
   libopencv-video2.4 - 2.4.3-r2
   opencv-apps - 2.4.3-r2
   opencv-samples - 2.4.3-r0
   python-opencv - 2.4.3-r2

You shouldn't need to mention them all as they will come in by
dependencies.  Try adding 'opensv-samples opencv-apps' to your image.
