Package inclusion

Package inclusion

[Carlos Sánchez de La Lama]

Hi all,

I have some doubts on how package inclusion in images is determined. For
example, when building core-image-base, I would say that both

kernel-module-uvesafb
kernel-module-input

are recommended (through RRECOMENDS in packagegroup-base).

However, -uvesafb makes it to the final image, whereas -input does not.
I double-checked on the running system under QEMU *and* reading the
image manifest at
tmp/deploy/images/qemux86/core-image-base-qemux86.manifest

I must be missing something. Can someone give me a pointer?

Thanks a lot, BR

Carlos

I don't see a reference to kernel-module-uvesafb in packagegroup-base.

If you would like to analyse the package dependency tree for an image one way
that works is to use buildhistory:

http://www.yoctoproject.org/docs/current/ref-manual/ref-manual.html#maintaining-build-output-quality

Among other things this will give you a .dot dependency graph file (for which 
I can recommend xdot.py as a viewer).

Cheers,
Paul

You are right, my bad. I was examining several cases and I used the
wrong one when writing the mail. I should have said

kernel-module-nls-utf8 (which goes into the image)
kernel-module-input (which does not make it to the image)

and both appear in RRECOMENDS_packagegroup-base.

I checked the buildhistory (nice report, BTW), and I see

"packagegroup-base" -> "kernel-module-nls-utf8" [style=dotted];

but not a trace of kernel-module-input. I do not understand why -input
gets a differnt handling than -nls-utf8. My guess is it gets excluded
somehow, but I have not found why/where.

Thanks!

Carlos

You definitely have the kernel-module-input package created - right? Because 
it's an RRECOMMENDS, that package can actually not be produced by the kernel 
(i.e. because the corresponding config option is 'y' or 'n' instead of 'm').

Another much less likely possibility is that you have BAD_RECOMMENDATIONS set 
to include kernel-module-input. bitbake -e | grep ^BAD_RECOMMENDATIONS will 
tell you if that is the case.

Paul

You got it. The package is not created.

I should have checked that before.

Thanks for your help, BR

Can i install tensorflow and h5py (since they are not there as recipes)
using Internet on yocto? (just the way they are installed on ubuntu or
other host OS)

Thanks

may be you can use on device SDK and build it natively on
your target

EXTRA_IMAGE_FEATURES_append = " tools-sdk"
IMAGE_INSTALL_append = " python coreutils findutils git zlib tar"

then checkout the sources on target and build it. You might need more
packages then keep adding them to IMAGE_INSTALL and rebuilding image
