Re: [Buildroot] [v2, PATCH] Makefile: add 'show-info-all'

[Julien Olivain via buildroot <buildroot@buildroot.org>]

Hi Thomas,

Thanks for the patch.

This new "show-info-all" should be documented in the
"make help" target, in the misc section:
https://gitlab.com/buildroot.org/buildroot/-/blob/2026.02/Makefile?ref_type=tags#L1204
saying it will show all packages available in Buildroot (not only
the selected ones). And possibly also in the manual:
https://gitlab.com/buildroot.org/buildroot/-/blob/2026.02/docs/manual/common-usage.adoc
in which you can say it is intended for Buildroot maintenance (sbom, 
cve, ...).

On my Fedora 43 system, running "make show-info-all" with this patch
shows the errors:

support/dependencies/check-host-cmake.sh: line 35: [: cmake: integer 
expected
support/dependencies/check-host-cmake.sh: line 38: [: cmake: integer 
expected

but the expected output is generated after.

When running in the reference docker image, it works as expected:
utils/docker-run make show-info-all

For some reasons, on Fedora 43, the script is called with:

support/dependencies/check-host-cmake.sh cmake cmake3

It should be called with $(BR2_CMAKE_VERSION_MIN).
See:
https://gitlab.com/buildroot.org/buildroot/-/blob/2026.02/support/dependencies/check-host-cmake.mk#L11

for example:
support/dependencies/check-host-cmake.sh 3.18 cmake cmake

I believe in your case of show-info-all, those dependencies checks
should not be called at all.

Could you add the small documentation description and improve
the srcipt to avoid the errors, please?

Best regards,

Julien.
