As far as I can see, this is using the standrad Linux out-of-tree
external module mechanism to build the emlog module. Buildroot has
an infrastructure to help write packages that build a kernel module:
https://buildroot.org/downloads/manual/manual.html#_infrastructure_for_packages_building_kernel_modules
Thomas and I believe emlog should use that kernel-module infra.
You just need to handle the nbcat userland utility with the
generic-package infra.
Care to update and respin, please?
In the meantime, I'm marking this patch as "Changes Requested" in our
Patchwork.
Thanks! :-)

I did not spot this during the previous review, and Arnout also didn't
spot it apparently, so maybe I'm missing something.
emlog is a kernel module, so surely it needs the Linux kernel to be
built beforehand. So your package should "depends on BR2_LINUX_KERNEL"
and have "linux" in EMLOG_DEPENDENCIES. Otherwise, I don't see how it
can even build.
Could you look into this, as well as the comments from Arnout, and
resend an updated version of your patch?
Thanks a lot!
Thomas

Doesn't $(TARGET_CONFIGURE_OPTS) work here? If not, it's better to explain that
in the commit message.

Also here a comment would be good:
# make install tries to strip, so install manually.
Otherwise, looks good to me, so you can add my

I guess this is a new version of the emlog patch, right?
If so, a new iteration should be labeled as "PATCH v2" and should carry
a changelog. See
https://buildroot.org/downloads/manual/manual.html#submitting-patches.
This helps us a lot to understand what has changed between the
different iterations of a patch.
Thanks!
