Hi team
Few weeks ago I was having some problems with open CV receipt. In the
begining I toght I was adding opencv tro my core-image-minimal-xfce
just with this:
IMAGE_INSTALL_append = " gcc gcc-dev openssh php mariadb opencv"
Now after booting the image I realize that none of the libraries for
open stack were added to my image
What I had to do was the following:
IMAGE_INSTALL_append = " libopencv-core-dev libopencv-highgui-dev
libopencv-imgproc-dev libopencv-objdetect-dev libopencv-ml-dev
opencv-staticdev python-opencv"
A recipe can produce several packages. As I can see on opencv recipe, it can
produced the following ones:
PACKAGES="opencv-staticdev opencv-dev opencv-dbg opencv-doc opencv
opencv-apps python-opencv"
and dynamic ones (depending on what else you have install)
PACKAGES_DYNAMIC="^opencv-locale-.* ^libopencv-.*"
For the opencv case, it happens that the package opencv is empty, so you
need to append the other sub-packages it produces into your IMAGE_INSTALL
variable.
So, it is not a bug, this is expected.
In my humble opinion this should change for OpenCV. But I would love
to hear the feedback from others
Not everyone that uses OpenCV wants to develop programs on the unit. Many
times all you need are prebuilt applications. Yocto is designed for the
most flexibility, hence packages are not "forced upon" you - you need to
ask for them.
In the case of OpenCV (again this discussion really belongs on the OpenEmbedded
developers list BTW), perhaps there should be a opencv-develop pseudo-package
which installs all the bits that you are asking for.
Even last night when one of the opencv developers ask me for python
opencv I had to add the last part python-opencv. That is not cool at
all . If I add opencv in the beginning I assume we are more than cool
with that and yocto will add all the packages . Unless I am doing
something wrong, in taht case I am more than happy to get the
feedback.
Thanks a lot for all the help . If someone else can reproduce this bug
I am more than happy to report it in bugzila (not sure the URL)
Hope it helps to cut the time of some others
Best regards
Victor Rodriguez
