Ryan, All,

On 2021-03-12 14:05 -0600, Ryan Barnett spake thusly:
> opkg-utils is a collection of bash and python scripts which require
> additional commands/tools be available for the bash scripts. The full
> list of dependencies that the opkg-util scripts require is:
> 
>   bash
>   binutils
>   bzip2
>   coreutils
>   diffutils
>   findutils
>   grep
>   gzip
>   lz4
>   python3
>   sed
>   tar
>   xz
> 
> Since buildroot requires that bash, binutils, bzip2, gzip, sed and tar
> be installed on the host system, only add dependencies on the
> remaining host tools.

We already implicitely require grep: we're calling it so many times in
the existing code. I am of the opinion that grep is a required package.

That it is inot in the manual, is probably because it is so wildely
installed by default in all distributions that we never had an issue
with it missing so far, so it was not added to the list of required
packages.

Yes, that's basically how that list came to be: someone reported an
issue about a tool missing, and it got added to the list (or we
instroduced a host version).

In the case of grep, I would say we should just require it on the host.

find is also on the same page: it is a required package.

As for coreutils, I would tend to be on the same page: it is a required
package.

However, we do have a host-coreutils package, but we only use when a
package needs either or both of 'ln --relative' or 'realpath'. See:
support/dependencies/check-host-coreutils.sh

If that is the case for opkg-utils, then it should add
$(BR2_COREUTILS_HOST_DEPENDENCY) to its _DEPENDENCIES. See:
    package/libselinux/libselinux.mk
    package/libsepol/libsepol.mk
    package/systemd/systemd.mk

Yann E. MORIN.
