Hi,
I'm trying to create a image recipe based on a existing one.
I've searched online, and I could find such an example.
My problem is that the image I what to serve as a base is changed in
another layer, and I want to include that changes.
Ex:
(tree)
Prj_root
-> layer1
-> recipes-core
-> images
-> my-image.bb [This is the base recipe]
-> layer2
-> recipes-core
-> images
-> my-image.bbappend [This is the changed one]
-> layer3
-> recipes-core
-> images
-> my-image-dev.bb [this is the new image, based on my-image]
my-image.bbappend is something like this:
--------------------- my-image.bbappend ---------
PROVIDES = "product"
IMAGE_INSTALL += " \
<some_packages> \
"
IMAGE_INSTALL_remove += " \
<other-packeges>
"
(+ other functions related with signing the image)
_________________________________________________
The final image is created with 'bitbake product'.
And, I want to create a dev image that must be based on the current
"product" image (my-image.bb + my-image.bbappend) with some dev
packages.
So, I need to include the changes that my-image.bbapend does to this
dev image I'm trying to create.
Tried simple create a new image that should be a copy of the working
one, and then add the needed packages for development.
So I did the following...
---------------- my-image-dev.bbappend ----------
SUMMARY = "dev Image"
require layer1/recipes-core/images/my-image.bb
------------------------------------------------
I can run 'bitbake my-image-dev' and it runs, but doesn't produce the
same output as 'bitbake product'.
Also, If I run 'bitbake my-image-dev' 1st, it finishes fine. Running
'bitbake product' after makes a bunch of other tasks and finishes fine.
Running again 'bitbake my-image-dev' finishes with an error on a
specific task. ( It shows that they are not building the same thing)
How can I do what I need?
NOTE: I can't change anything in the layer1 and layer2.
PS. Also tried to require the bbappend file, but bitbake fails saying
that it's not a bitbake file.
Thanks in advanced.
