So it looks like the number of /bin/awk have increased so the patch will

The best solution might be to add kernel patches but since the number of
/bin/awk have increased I think that this is fine in the kernel universe
but a problem in poky universe. So by adding it to kernel-devsrc it will
make sure that when the kernel get's tainted in the future it will not
break the rpm build. This is a "bug" only when using rpm ipk will not
detect it as a problem.
I'm ok with this type of solution as well, since this is similar
to what we've had to do with perf in the past (sed and modify versus
patching). I can always patch and fix things in linux-yocto, but then
another other kernel still suffers the issue.
can we fix it in upstream kernel to use something like
#!/usr/bin/env awk
may be ?

Yup. That works too (as would a variable from the env), but we'll still
need a sed based patch in the short term.


It would be better if folks with this problem also send patches upstream
to allow us to vary the location of awk via a variable, since that would
eventually fix all kernels without needing any modifications .. but that
is a medium term time play, versus doing the sed operation.

If you have a patch to kernel-devsrc in master, feel free to send it
and cc' me, and I can pull it into my queue, test and then send it in
my next pull request.

I am trying to add the kernel devsrc to the SDK but I am getting the
following error

Problem: conflicting requests
- nothing provides /bin/awk needed by kernel-devsrc-1.0-r0.imx8mqevk

I have applied the following patch to try and fix this problem.

I have verified that it was applied and run kernel-devsrc works. The
error is from do_populate_sdk and I am suspecting that the problem
is related to me using rpm. I believe rpm might be to smart in this
case detecting the dependency and resulting dnf from failing when
running the task do_populate_sdk. Any suggestion on how to get
forward on this error. I would like to run dnf manually to check any
dependency of the kernel-devsrc rpm package but cannot figure out how.
