Create iso image using the wic script in the isar package

[John W]

Hi,

I was able to create a custom image in wic format with isar and now trying to create a bootable iso image. I found the wic script in the isar package and attempted to run with the command:

wic create mkhybridiso -e isar-image-base

However I got the following error:

INFO: Building wic-tools...

    raise CalledProcessError(retcode, cmd)
subprocess.CalledProcessError: Command '['bitbake', 'wic-tools']' returned non-zero exit status 1.

Is there any suggestion on how to resolve this issue?

Thanks!

Hello John,

As you can see in generate_wic_image() task code, Isar supposed to call WIC
script inside special chroot environment. You can take this task as a
reference
to create you own task with additional imager_run call of custom WIC
command.

P.S.
WIC script was brought from OpenEmbedded which really has wic-tools.bb
recipe.
Isar don't have such a recipe, so this fallback is not working.
