Hello,
I really don't know whether this is feasible or not, but I'm trying to
build a yocto image (custom image) with conditional configuration
fragments.
Today I have 2 image type: one for deployment purpose and another for
debug purpose. Debug images is only a superset of deployment image with
additional debug capabilities: nothing else.
However now I would like to add additional linux kernel features to this
debug image (ex: CONFIG_DEBUG_INFO=y).
I want to add this feature into debug image, but NOT in deployment image.
I was thinking to create a .bbappend to my linux .bb file, but again I
don't see how to use .bbappend in a conditional way (based on image name
for instance)
Do you have any idea to perform such request ?
Fragments are either just added to the SRC_URI or KERNEL_FEATURES via
the normal variable assignment rules.
So if you have something that you can test on (image/distro feature as
an example), you can use anonymous python and do a conditional
assignment.
Others on the list may have more elegant suggestions!
This can't work for what Pierre is asking for. You can't have a single recipe
built differently depending on what image is being built - our system does not
work that way. At a basic level, recipes create packages, and then the image
recipe selects which packages should go into the image.
Given that the kernel does not produce named packages in our system, I'm not
sure we currently have a way to build two different kernel recipes and select
one in one image and another in another image (which is the way we normally
handle this kind of requirement with other recipes.) Probably the only way to
do this is to have two completely separate build directories.
Many Thanks for your answers.
Thus I was thinking of making 2 separate linux.bb, one for deployment and the
other for debug (i.e. linux-debug.bb) and update
PREFERRED_PROVIDER_virtual/kernel accordingly.
But is there an automatic way to select proper .bb (linux.bb or linux-debug.bb)
file like setting this variable(PREFERRED_PROVIDER_virtual/kernel) within the
.bb image file ? Won't it work ?
Another option which is coming on top of my mind:
SRC_URI_append_<image-name> = " file://configuration_segment.cfg"
Is it something realistic and working ?
The image name would have to be an OVERRIDE value for variables.
Last I checked it wasn't, but perhaps Paul can straighten out that
point as well :)
Cheers,
Bruce
Please advise
Many thanks in advance
