Finding out the IMAGE_BASENAME of the image beeing built

Finding out the IMAGE_BASENAME of the image beeing built

[Ulf Samuelsson]

Trying create a programming script recipe and need to find out the 
IMAGE_BASENAME of the bitbake target
so I can get the filename of the image

${MACHINE}-${IMAGE_BASENAME}.ubi

I.E: if I do

$ MACHINE=beagleboard  bitbake some-image

and "some-image_1.0.bb" contains

IMAGE_BASENAME = "renamed-image"

Then the resulting image will be

     "beagleboard-renamed-image.ubi"

How get this info from another recipe?

Hi Ulf,

$ MACHINE=beagleboard  bitbake -e some-image

shows all variables including $IMAGE_BASENAME without actually
building the image.
Using grep you can take the value of IMAGE_BASENAME, like as:

$ MACHINE=beagleboard  bitbake -e some-image | grep ^IMAGE_BASENAME

Does it help you?

If possible, consider to use hooks, for example, IMAGE_POSTPROCESS_COMMAND .
Refer image.bbclass for details. It might make things straiter.

You can't. The way to handle this is as part of do_rootfs itself (e.g. from a 
script called from ROOTFS_POSTPROCESS_COMMAND or IMAGE_POSTPROCESS_COMMAND).

Thanks,

bitbake is already running to build my recipe.
Not sure that running "bitbake -e" is OK while bitbake is already running.

IMAGE_BASENAME is set to my recipe, so I cannot use this directly.

I know I can do it inside the "some-image.bb" recipe, but I would like
to do it inside my recipe. Otherwise all images must be customized
for my recipe, which is not a good idea.

If I could do an IMAGE_POSTPROCESS_COMMAND in my recipe, then
that would be OK, but I then still need to find out what the image name is.

OK, thanks

I tried to define  "configure-sam-ba.bbclass" which is inherited by my 
image.

configure-sam-ba.bbclass:
----------------------------------------------------------------------------------------------------------

SCRIPTFILE_TEMPLATE    = "${DEPLOY_DIR_IMAGE}/scripts/${MACHINE}.tcl"
SCRIPTFILE                      = 
"${DEPLOY_DIR_IMAGE}/scripts/${IMAGE_LINK_NAME}-${MACHINE}.tcl"
PROGFILE_TEMPLATE      = "${DEPLOY_DIR_IMAGE}/scripts/prog.sh"
PROGFILE                        = 
"${DEPLOY_DIR_IMAGE}/scripts/prog-${IMAGE_LINK_NAME}-${MACHINE}.sh"

sam-ba_setup () {

     if [ -e  ${PROGFILE_TEMPLATE} ] ; then
         sed    -i    s/#MACHINE#/${MACHINE}/ ${PROGFILE_TEMPLATE}
         sed    -i    s/#IMAGE#/${IMAGE_LINK_NAME}/ ${PROGFILE_TEMPLATE}
     fi
     cp    ${PROGFILE_TEMPLATE}    ${PROGFILE}

     if [ -e  ${SCRIPTFILE_TEMPLATE} ] ; then
         sed    -i    s/rootfs.ubi/${IMAGE_LINK_NAME}-${MACHINE}/ 
${SCRIPTFILE_TEMPLATE}
     fi
     cp    ${SCRIPTFILE_TEMPLATE}    ${SCRIPTFILE}
}

EXPORT_FUNCTIONS sam-ba_setup

EXTRA_IMAGEDEPENDS_append_mymachine = ' sam-ba'
IMAGE_POSTPROCESS_COMMAND_append_mymachine = " sam-ba_setup; "
----------------------------------------------------------------------------------------------------------
myimage.bb: contains.

inherit configure-sam-ba
----------------------------
It appears that the "configure-sam-ba.bbclass" file is found.
If I change the filename in the inherit statement I get an error message.

inherit configure-sam-ba-x
I get an error message.

Another indication is that the call to "sam-ba_setup;"  is inserted in 
the "run.do_rootfs.*" script,
but the script does not contain the "sam-ba_setup" subroutine.

In some places IMAGE_POSTPROCESS_COMMAND contains " 
rootfs_update_timestamp ",
from image.bbclass which *is* included in the "run.do_rootfs.*" script.

Should you not be able to use commands from a bbclass as 
PRE/POSTPROCESS_COMMAND?

A standard shell command will work, but since I need a number of 
commands, it seems
cleaner to implement it in a bbclass file.
This is my first bbclass file, so there may be things, I don't understand...

Hi Ulf,

I couldn't find the reason your recipe is stand alone,
because it doesn't generate image by itself. Does it?

My idea is written under the quote. How is it?


Let me go back to your question in first mail.

----  your-image.bb ---- from here ----
include some-image.bb

 ((( use  ${IMAGE_BASENAME} and ${MACHINE} for your process )))

 ((( after that, redefine IMAGE_BASENAME and other variables if necessary. )))

---- your-image.bb ---- to here ----
