 These look like UNINSTALL commands, not CLEAN commands.

 Not that it's terribly important.

Ah right. Actually the first line should be part of CLEAN commands, and
the three last lines should be part of the UNINSTALL commands.

Are they people who actually care about those CLEAN and UNINSTALL
commands? Is it worth keeping support for them?

IIRC these targets cannot in general work correctly with the Buildroot
structure, and making them work would require a massive change, with a
big increase in complexity.

Moreover, many packages do not implement the CLEAN and UNINSTALL targets:

$ git grep -l GENTARGETS package/|grep -E '^package/[a-z]'|wc -l
111
$ git grep -l GENTARGETS package/|grep -E '^package/[a-z]'| \
     xargs grep -l '_CLEAN_CMDS'|wc -l
51
$ git grep -l GENTARGETS package/|grep -E '^package/[a-z]'| \
     xargs grep -l '_UNINSTALL_.*_CMDS'|wc -l
73

meaning that probably they are not so interesting to everybody out there.

As for me, I have never been relying on them. I prefer to distclean and
rebuild when necessary. It's reliable, and not that painful with a
reasonably recent build machine and ccache enabled.

So, my vote for dropping them.
(Or should there be a specific thread for this topic?)

I definitely agree with you here. If they exist, then they should be
reliable. But I'm not sure it's going to be easy to make them fully
reliable. And then can be dangerous, because they are not recursive:
you can remove a given library without removing the other libraries or
applications that depend on it.

So I would also vote for dropping them. But we should then also drop it
from AUTOTARGETS/CMAKETARGETS packages.

Thomas

[Buildroot] [PATCH 2/2] Add MXS bootlets package

[Maxime Ripard]

MXS platforms (imx23 and imx28) are relying on bootlets as their first
stage bootloaders, that can then either start a regular second stage
bootloader or directly a Linux kernel. However, the Makefile allows
only to build u-boot and linux images at the same time, which is
not very convenient as we will more likely use only one of them,
so we need to duplicate a bit what is already done so that we are able
to choose what we want to generate.

[Buildroot] [PATCH 2/2] Add MXS bootlets package

[Thomas Petazzoni]

Le Wed, 18 Jul 2012 18:02:43 +0200,
Maxime Ripard <maxime.ripard@free-electrons.com> a ?crit :

> MXS platforms (imx23 and imx28) are relying on bootlets as their first
> stage bootloaders, that can then either start a regular second stage
> bootloader or directly a Linux kernel. However, the Makefile allows
> only to build u-boot and linux images at the same time, which is
> not very convenient as we will more likely use only one of them,
> so we need to duplicate a bit what is already done so that we are able
> to choose what we want to generate.
