[Buildroot] [PATCH 1/6] barebox: fix coding style

Fabio, All,

Although we have no written rule about thus, I'd rather that folded-lines
assignments continue after the '=' sign, like:

BAREBOX_MAKE_FLAGS = ARCH=$(BAREBOX_ARCH) CROSS_COMPILE="$(CCACHE) \
                     $(TARGET_CROSS)"

It makes it easier to see the assignment.

Ditto.

But I'd like the maintainer to Ack this before you resend. I have no
strong opinion about it, I just find it easier to read...

 Splitting a line between quotes is evil.

 Or better yet (and this is the unwritten rule that we tend to follow):

BAREBOX_MAKE_FLAGS = \
	ARCH=$(BAREBOX_ARCH) \
	CROSS_COMPILE="$(CCACHE) $(TARGET_CROSS)"

 Splitting a single path is also evil. We do usually keep the long lines
in such a case.

 This one is probably OK :-)

Hi Arnout and Yann,
thanks for reviewing the patch.

It's a matter of code style because it works fine, doesn't it?

I don't have a strong opinion about this, i'd like also to be
consistent to the style used in buildroot and i was unable to find any
code that follow that rule.

 Yes. It's evil in the sense of: it will come out to bite the programmer
later on.

 Yes, but this time I exaggerated - splitting a path like that is not
really evil, it's just something I would rather not see.

 Reviewing this patch leads to a few more opportunities, though. So these
are commented below.

 Actually, this is used in just one place so perhaps it can be removed.

 quiet is not used. It is exported though, which is probably a bad idea
anyway.

 CONFIG_SHELL should be passed with the rest of the kconfig environment,

Hi Arnout,
thanks for reviewing.
I will work on your suggestions after this patch is merged because if
possible i want to avoid the pain to rebase endless other patches over
this one.

Hi Peter,
any chance for this patch to being merged?
it's already acked and it's one month old.

The rebased patch is:

Thanks and best regards

[Buildroot] [PATCH 4/6] luajit: needs for 32bit archictectures a 32bit host gcc

[Fabio Porcedda]

For 32 bit archictectures the luajit package needs a host compiler
able to generate 32 bit code using the "-m32" option so check if that
option is supported.

[Buildroot] [PATCH 5/6] infra: add to luarocks support for top-level parallel make

[Fabio Porcedda]

The host-luarock dependency is not always satisfied for the extract
phase because the %-extract target is not anymore in the dependency
chain.
To be sure that the dependency is satfied add the dependency to the
stamp file $(%_TARGET_EXTRACT) instead of the %-extract target.

[Buildroot] [PATCH 6/6] Makefile: do not add the toolchain target to the TARGETS variable

Do not add the toolchain target to the TARGETS variable because now the
toolchain target is a dependency added automatically so it is not
necessary to add it anymore.

 I disagree with this one. When you run make, you expect buildroot to
build the toolchain even if no target package is selected. One use case I
can think of: when preparing an internal toolchain for use as an external
toolchain in later builds.

Take in account that the "toolchain" target is always built because is
a dependency of the "busybox" package that is always build and cannot
be disabled and
the "toolchain-buildroot" and "toolchain-external" are always enabled
in the Config.in.

I was thinking that the "toolchain" target is a package that uses tha
package infrastructure, what about using the Config.in:

diff --git a/toolchain/Config.in b/toolchain/Config.in

I think this is more coherent to other always enabled packages like
busybox and toolchain-*.

 busybox can be disabled (if you set the init system to "none").

 toolchain, toolchain-buildroot and toolchain-external are not added to
TARGETS because BR2_PACKAGE_TOOLCHAIN... is not defined.

 That would indeed be an option (it would have to be
BR2_PACKAGE_TOOLCHAIN, but that's a minor detail). I'm not sure, however,
if this is better than TARGETS := toolchain in the Makefile.


 Actually, I am in favour of adding blind options for everything that
uses the package infrastructure. That will allow us to do things like
checking select/DEPENDENCIES consistency, and generally makes things more
consistent.

Indeed, and I very often uses that when I want to just test a single
package I'm adding.

Good idea, next time i will test a package i will do that.

I didn't know that, great!

They are added to targets, just use this command to check it:

$ make defconfig && make show-targets

toolchain-buildroot toolchain busybox target-generic-securetty
target-generic-hostname target-generic-issue target-root-passwd
target-generic-getty-busybox target-generic-do-remount-rw rootfs-tar

I've not used the PACKAGE prefix because it's not used at all for the
toolchain config options, like the  BR2_TOOLCHAIN_BUILDROOT option.

 Yeah, I forgot about this condition in pkg-generic.mk:

else ifneq ($(filter toolchain/%,$(pkgdir)),)
$(2)_KCONFIG_VAR = BR2_$(2)

 But first, Peter, (and other buildroot maintainers as well), do you
agree that it would be a good idea to have blind Kconfig symbols for
everything that uses the package infrastructure?

I've forgotten to add the V2 subfix to the patchset.
