[Buildroot] [PATCH 0/3] core: add kconfigsymbols to packages (branch yem/check-target-packages)

[Yann E. MORIN]

Hello All!

Since we check that packages in _DEPENDENCIES are enabled at the Kconfig
level, it means all the target packages need to have a Kconfig symbol.

This is currently not the case for quite a few of them:
  - linux-headers
  - netbsd-queue
  - virtual packages
  - a few more...

This series fixes the most critical ones (the three identified in the
list above); others will be fixed in later patches when the autobulders
find them.


Regards,
Yann E. MORIN.

[Buildroot] [PATCH 1/3] package/c-libraries: need linux-headers

[Yann E. MORIN]

Now that we check that a target package in the _DEPENDENCIES of another
package has to be enabled in config, all target packages must have a
kconfig symbol.

Add a Kconfig symbol for linux-headers, and select it from the packages
that depends on it (C libraries).

Also remove the now-misleading comments "for legal-info" from the C
libraries.

Fixes:

I've applied, even though I'm not super happy with the fact that we
already had a (useless?) BR2_PACKAGE_HOST_LINUX_HEADERS option, and we
now have both a Config.in.host and a Config.in file for what is really
a target package...

Ideally, we would move all the options to the Config.in file, and
rename them.. but that would cause so much Config.in.legacy trouble :-/

Thanks,

Thomas

I've applied, but I realized afterwards that you forgot the external
toolchain case, so I did a follow-up commit to fix this case as well.

Thanks!

I changed this to:

		-a "$($(PKG)_IS_VIRTUAL)" != "YES" \

which I believe is a bit more logical.

I wasn't sure whether a new variable was needed. We could have used
$($(PKG)_VERSION) != "virtual", but that would have failed if one day
we have a normal package that really has a version named "virtual" for
some reason.

We can anyway change this later on if others have better suggestions.

Thanks,

Thomas
