Recipe do_install priority

Recipe do_install priority

[Mauro Ziliani]

Hi all.

I'm Mauro.

I have to resolve this matter.

The recipe  init-ifupdown.bb install file interfaces in /etc/network.


I build a library which need to install the same file in the same folder.

This library is managed by its own recipe  library.bb in my meta-mylayer.


How can I tell to bitbake to install library after init-ifupdown in 
final image?


The best for me should be drive this behavoir in the recipe-image.bb in 
this way


library:do_install after init-ifupdown:do_install


that means  run do_install of library.bb afger do_install of 
init-ifupdown.bb


Any idea?

do_install() is not installing things into the final image. It is
installing items to the target location under a separate 'destination
directory', independently of anything else that installs to the same target
location under different destination directory. If the filenames are the
same, you will get a file conflict error later on when the image is
constructed.

It would help if you describe in detail what file do you intend to replace,
and why.

Hi Mauro, all,

During the creation of the rootfs of your image yocto will try to install
both packages, and should complain loudly because the same file is provided
by two packages.

There are a few ways you can do this properly:

a) the straight-forware way is be to create a bbappend for init-ifupdown
that updates the contentious file with the content that you need, and NOT
provide this file in your library.bb

b) you could also createa bbappend for init-ifupdown which remove that file
from the installation in a do_install_append, and then you are free to
install it in your library.bb as it is not longer part of init-ifupdown.
This is not too complex.

c) another option is to try to use alternatives which allows the same file
to be delivered by several packages, and which one is used is selected at
install and/or runtime by using symbolic links (example: vi vs vim). This
requires a bit more research.

I am afraid that options other than these straight-forward ones will
qualify for the title of "horrible hacks"... :-)

Kind regards, Laurent.

this is best course of action, for maintainance POV as well as 
readability, I know of custom packages that bundled bits and pieces into 
a single package like this and call it some meta package but ideally, 
its better to stay with upstream packaging conventions. Its less work 
eventually to maintain.
