Hello all,
I have python module of OpenCV for python 2.7 on my Yocto image adding via
local.conf
IMAGE_INSTALL_append += “ python-opencv”
Can you advice how to add opencv binding for python 3?
Thanks.

Ditto for Robert’s comment. Please look at the bitbake manual and
understand what the syntax means [1].
Also, “python-foo” means the python2 version. The default PACKAGECONFIG
[2] for opencv builds for python3. You need “python3-opencv”.
Finally, I would encourage you to use CORE_IMAGE_EXTRA_INSTALL [3] rather
than IMAGE_INSTALL in the local.conf context.

That I was thinking to have “python3-opencv” but it's failing to build
I found opencv_3.1.bbappend with my sources where I see
PACKAGECONFIG_remove_imx = "eigen python3"
I guess that might causing a problem to build opencv for python3... I'll
remove and check again to build.
BTW what's the benefit of using CORE_IMAGE_EXTRA_INSTALL over
IMAGE_INSTALL_append ?

By allowing "python3-opencv" I end up with errors ....
ERROR: fsl-image-qt5-1.0-r0 do_rootfs: python3-opencv not found in the
feeds .
ERROR: fsl-image-qt5-1.0-r0 do_rootfs: This is often caused by an empty
package declared in a recipe's PACKAGES variable. (Empty packages are not
constructed unless ALLOW_EMPTY_<pkg> = '1' is used.)
ERROR: fsl-image-qt5-1.0-r0 do_rootfs: Function failed: do_rootfs
where to look at on problem?

FYI This suggestion is fine, however it is not sufficient. There is an
inherent assumption that image
is inheriting core-image which is implied and not explicitly
mentioned. many users do not inherit
core-image hence this suggestion will be moot for them.
