Syntax for requiring a dependency task's deploy phase to be finished

Syntax for requiring a dependency task's deploy phase to be finished

[Matt Hoosier]

Hi,

I'm trying to build a kernel containing an initramfs linked directly
into the kernel binary. This is inspired by the recent discussion
here: building a minimal image with IMAGE_FSTYPE set to cpio.

I need to be sure that by the time the kernel's do_compile task
executes, the minimal image has been deploy to ${DEPLOY_DIR}/image.
What's the right way to write this dependency?

Thanks

If I understand correctly you want something like

do_compile[depends] += "minimal-image:do_deploy"

inside the kernel recipe where "minimal-image" is the name of the image
recipe.

Cheers,

Richard

And make sure *nothing* in that image depends on a kernel at buildtime,
otherwise bitbake will start spewing incomprehensible backtraces :)
A better approach would be to write a bbclass that takes a kernel image
and initramfs and glues those together.

Koen

Okay, thanks to both. Richard's suggestion solves the immediate need.
