The $(BUILD_DIR)/.root rule is executed as part of the 'dirs'
target. The 'dirs' target is re-executed at every execution of 'make
external-deps', and make external-deps explicitly tells make to ignore
targets that have already been made (through the -B option). This
means that the $(BUILD_DIR)/.root rule has to be idempotant, which was
not the case this the introduction of the lib32/lib64 symbolic
link.
Running 'make external-deps' three times in a row was sufficient to
trigger an error due to symbolic links being incorrectly created. This
patch fixes that.

This should probably be taken for 2013.08.1 as a fix of 'make

Thomas, there is a patch in patchwork that renames the
$(BUILD_DIR)/.root stamp file, by J?r?me.
Although it is not directly related to the above, could you have a look at it?
http://patchwork.ozlabs.org/patch/265680/
Thanks,
Thomas

Wouldn't just changing the "ln -s" to "ln -snf" be sufficient? After all,
that's what is being done to make $(STAGING_DIR):
$(STAGING_DIR):
@mkdir -p $(STAGING_DIR)/bin
@mkdir -p $(STAGING_DIR)/lib
@ln -snf lib $(STAGING_DIR)/$(LIB_SYMLINK)
@mkdir -p $(STAGING_DIR)/usr/lib
@ln -snf lib $(STAGING_DIR)/usr/$(LIB_SYMLINK)
....

I think, when I tried it, it wasn't working: at the second invocation,
it creates a symbolic link *within* the lib directory. Example:
thomas at skate:/tmp$ mkdir target
thomas at skate:/tmp$ cd target/
thomas at skate:/tmp/target$ ls
thomas at skate:/tmp/target$ mkdir lib
thomas at skate:/tmp/target$ ls lib/
# lib/ is empty
thomas at skate:/tmp/target$ ln -sf lib lib32
thomas at skate:/tmp/target$ ls -l
total 0
drwxrwxr-x 2 thomas thomas 40 sept. 8 15:27 lib
lrwxrwxrwx 1 thomas thomas 3 sept. 8 15:28 lib32 -> lib
thomas at skate:/tmp/target$ ls lib/
# we have the symbolic link, lib/ is still empty. Now we will create
# the symbolic link again
thomas at skate:/tmp/target$ ln -sf lib lib32
thomas at skate:/tmp/target$ ls -l
total 0
drwxrwxr-x 2 thomas thomas 60 sept. 8 15:28 lib
lrwxrwxrwx 1 thomas thomas 3 sept. 8 15:28 lib32 -> lib
thomas at skate:/tmp/target$ ls -l lib/
total 0
lrwxrwxrwx 1 thomas thomas 3 sept. 8 15:28 lib -> lib
# A stale symbolic link was created in lib/
Best regards,
Thomas

"ln -sf" is not sufficient for a symlink to a directory - you need "ln
-snf" - the -n treats the directory symlink as a file, which prevents this
very problem.
Example based on your example:
/tmp$ mkdir -p target/lib
/tmp$ cd target
/tmp/target$ ls lib/
# lib/ is empty
/tmp/target$ ln -snf lib lib32
/tmp/target$ ls -l
total 4
drwxrwxr-x 2 dmanchego dmanchego 4096 Sep 8 12:49 lib
lrwxrwxrwx 1 dmanchego dmanchego 3 Sep 8 12:50 lib32 -> lib
/tmp/target$ ls lib/
# we have the symbolic link, lib/ is empty
/tmp/target$ ln -snf lib lib32
/tmp/target$ ls -l
total 4
drwxrwxr-x 2 dmanchego dmanchego 4096 Sep 8 12:49 lib
lrwxrwxrwx 1 dmanchego dmanchego 3 Sep 8 12:50 lib32 -> lib
/tmp/target$ ls lib/
# still good!
/tmp/target$ ln -snf lib lib32
/tmp/target$ ls -l
total 4
drwxrwxr-x 2 dmanchego dmanchego 4096 Sep 8 12:49 lib
lrwxrwxrwx 1 dmanchego dmanchego 3 Sep 8 12:50 lib32 -> lib
/tmp/target$ ls lib/
# still good!
Using the "ln -snf" lets you drop the if statements, so it seems desirable.

Aah, good!

Right, makes sense. I'll fix this up for the next iteration of the
patch series.

ln -sf no, but ln -snf yes. I'll fix up the patch and resend.

In order to avoid the work of converting the toolchain-crosstool-ng
logic to the package infrastructure, we remove it from Buildroot,
since it has been deprecated since quite some time.
Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

If we consider it too early to get rid of the Crosstool-NG backend
entirely, then it can of course be converted to the package
infrastructure, with quite a bit of effort (which we wanted to avoid
for now).

I don't care we remove it.
One of the blocking points that users were concerned about was to be
able to generate glibc/eglibc-based toolchains directly from within
Buildroot, hence some chimed in to keep the crosstool-NG backend.
Now that Buildroot can buid glibc/eglibc-based toolchain with its
internal backend, I see no reason to keep the crosstool-Ng backend at
all. So:
Acked-by: "Yann E. MORIN" <yann.morin.1998@free.fr>
As I said in a recently-posted patch (changes the manual to state the
crosstool-NG backend was deprecated), people that really want to use
crosstool-Ng can still do so outside of Buildroot, and use that
toolchain as an external toolchain.
Regards,
Yann E. MORIN.

BTW, you forgot to remove references to the crosstool-NG backend from
the manual while at it. ;-)

Yes, that's intentional for now. I've sent this patch set as an RFC to
get some feedback and testing. If the feedback is positive, I'll post
an updated version that includes the changes to the manual.
Thanks,

I still found two references to CTNG in:
package/Makefile.in:137:ifeq ($(BR2_TOOLCHAIN_BUILDROOT)$(BR2_TOOLCHAIN_CTNG),y)
package/libglib2/libglib2.mk:55:ifeq
($(BR2_UCLIBC_VERSION_0_9_32)$(BR2_TOOLCHAIN_CTNG_uClibc)$(BR2_TOOLCHAIN_EXTERNAL_UCLIBC)$(BR2_TOOLCHAIN_EXTERNAL_XILINX_MICROBLAZEEL_V2)$(BR2_TOOLCHAIN_EXTERNAL_XILINX_MICROBLAZEBE_V2),y)
Other than this, I also don't have a problem of removing the
crosstool-ng support inside buildroot. I was using it before, but now
successfully migrated to an external crosstool-ng repo.
Best regards,
Thomas

I have nothing against the removal of crosstool-NG.
I'm happy with using ct-NG to build a toolchain and use it inBR as an
external toolchain.

The ext-tool.mk logic uses the TOOLCHAIN_EXTERNAL_PREFIX variable
unconditionally, even if the external toolchain is not used. Until now
this wasn't a problem since ext-tool.mk was only included when the
external toolchain backend was selected, but the next patches are
going to include this file unconditionally.

The helpers.mk file is no longer used by the Crosstool-NG backend, so
it is moved into the toolchain/toolchain-external/ directory.

Ok, but you're still including this file. The inclusion is removedin
later patches, it should be done here.This is just to improve
bisectability, I'm ok with the idea.

This commit introduces a virtual package called 'toolchain', located
in 'toolchain/toolchain', which simply depends on
'toolchain-buildroot' or 'toolchain-external' depending on the
selected toolchain backend.
For now, toolchain-buildroot and toolchain-external are still manual
make targets, but the following patches convert those backends to use
the package infrastructure as well.
In addition to this:
* The main Makefile is modified to always make BASE_TARGETS point to
this new toolchain virtual package.
* The main Makefile is changed to include all the toolchain/*/*.mk
files: the toolchain virtual package, and the toolchain-buildroot
and toolchain-external directories.
* The dependency of the toolchain on prepare dirs and dependencies is
moved to the toolchain virtual package. It is moved as a
prerequisite of the "toolchain-source" rule to ensure that all
directories are prepared before we even start extracting the
toolchain.

At first sight I thought this might be a bug, because the += becamea =.
But since this is the only place where we set BASE_TARGETS this isnot a
problem of course.
I like this cleanup work, thanks.

This commit converts the toolchain-buildroot logic to the package
infrastructure. The package is fairly simple as it only defines
BUILDROOT_LIBC, and depends on host-gcc-final to get the overall
internal toolchain build logic started.

Until now, the make source, make external-deps and make legal-info
where relying on enumerating the packages by looking at $(TARGETS)
which contains only the target packages and not the host
packages. Thanks to the TARGET_HOST_DEPS and HOST_DEPS variables, it
was doing a two-level resolution of host package dependencies, but it
was not entirely correct since the dependency chain might be deeper
than that: some packages could be missed.
From an idea of Arnout, this patch introduces in each package
additional targets <pkg>-all-source and <pkg>-all-legal-info that
executes the 'source' and 'legal-info' targets for this package and
all its dependencies, be they target or host dependencies.
This provides a much cleaner implementation of this mechanism, which
is also more robust.

Am I correct in understanding that, due to the full dependency chain,
TARGETS_SOURCE will have many duplicate entries?
When executing 'make source', then, each of these targets will be
executed multiple times, correct? Even though the actual download will
only be executed once for each package, I wonder if there can be other
side effects by executing the targets multiple times. Would it make
sense to do $(shell sort -u ... ) here?

Well, TARGETS_SOURCE itself will not have many duplicate entries: in
the TARGETS variable, each selected package is only mentioned once, and
TARGETS_SOURCE has the exact same number of entries as TARGETS, except
that each word in TARGETS is replaced by %-all-source (I'm excluding
BASE_TARGETS here, but it only ever contains one entry: 'toolchain').
However, when *evaluating* those targets, we will indeed be looking
multiple times at the same dependencies.

As explained above, no: TARGETS_SOURCE by itself does not contain any
duplicated entry. It's the fact of evaluating each target in
TARGETS_SOURCE that will lead to looking multiple times at the same
things. But I'm not sure how to solve that.
Best regards,
Thomas

Ah yes, correct. Then I also don't see a simple solution...

Converting the external toolchain logic into a package raises a very
special use case that wasn't handled by the package infrastructure:
the Blackfin toolchain is delivered as two tarballs instead of
one. Unfortunately <pkg>_SOURCE only allows to pass one tarball name.
However, we really want both tarballs to be known by the package
infrastructure, so that the normal 'source' and 'external-deps'
mechanism work fine.
In order to achieve this, we add a <pkg>_SOURCE_ADDONS variable, which
allows a package to list other stuff it would like to see downloaded,
but that are otherwise not used by the package infrastructure itself:
it is up to the package to do it by itself.

What about allowing FOO_SOURCE to contain multiple words directly, and
thus not introducing a new variable? The package infrastructure can
download each word of FOO_SOURCE, but only extract (and otherwise use)
the first one. Any subsequent word has to be handled by the package
itself.
Best regards,
Thomas

Dear Thomas De Schampheleire,

The problem is that the default extract step needs to know what to do.
And what it does today is that it extracts the tarball whose name is
given in FOO_SOURCE. If we put several words in FOO_SOURCE, then what
should be the semantic of the default extract commands? Extract the
first one? All of them?
That's why I've decided to go with another variable, which really means
"I want this stuff to be downloaded, but don't do anything with it, the
package recipe will take care of it".
Of course, I'm open to changing the semantic of FOO_SOURCE instead, we
would just need to define what this new semantic should be.
Thanks!
Thomas

I'm more in favour of the <pkg>_SOURCE_ADDONS proposal. I think having
multiple _SOURCE files would be confusing.

Ok, fair enough.
I think you should add this to the documentation, then.

I also think keeping things separate is the best option to avoid confusion.
But to make it even more clear, I would name the variable _EXTRA_DOWNLOADS.

This commit converts the 'toolchain-external' logic to the package
infrastructure.
The TOOLCHAIN_EXTERNAL_DIR variable (which points to where the
toolchain is located) is renamed to TOOLCHAIN_EXTERNAL_INSTALL_DIR,
because the former conflicts with the package infrastructure (which
defines the <pkg>_DIR variable for each package as pointing to its
build directory).
The new _SOURCE_ADDONS mechanism is used for Blackfin toolchains.
The extract, configuration and installation steps are converted inside
the <pkg>_EXTRACT_CMDS, <pkg>_CONFIGURE_CMDS and
<pkg>_INSTALL_STAGING_CMDS.

Given that the extract commands are now very similar between blackfin
and non-blackfin, wouldn't it make more sense to define it once and
tweak it based on a variable?
Something like (quick and untested):
ifeq ($(BR2_TOOLCHAIN_EXTERNAL_BLACKFIN_UCLINUX_2012R1)$(BR2_TOOLCHAIN_EXTERNAL_BLACKFIN_UCLINUX_2012R2),y)
TOOLCHAIN_EXTERNAL_TAR_OPTIONS = $(TAR_STRIP_COMPONENTS)=3 --hard-dereference
else
TOOLCHAIN_EXTERNAL_TAR_OPTIONS = $(TAR_STRIP_COMPONENTS)=1
--exclude='usr/lib/locale/*'
endif
define TOOLCHAIN_EXTERNAL_EXTRACT_CMDS
mkdir -p $(TOOLCHAIN_EXTERNAL_INSTALL_DIR)
$(INFLATE$(suffix $(TOOLCHAIN_EXTERNAL_SOURCE)))
$(DL_DIR)/$(TOOLCHAIN_EXTERNAL_SOURCE) | \
$(TAR) $(TOOLCHAIN_EXTERNAL_TAR_OPTIONS) -C
$(TOOLCHAIN_EXTERNAL_INSTALL_DIR) $(TAR_OPTIONS) -
if [ -n "$(TOOLCHAIN_EXTERNAL_SOURCE_ADDONS)" ]; then \
$(INFLATE$(suffix $(TOOLCHAIN_EXTERNAL_SOURCE_ADDONS)))
$(DL_DIR)/$(TOOLCHAIN_EXTERNAL_SOURCE_ADDONS) | \
$(TAR) $(TOOLCHAIN_EXTERNAL_TAR_OPTIONS) -C
$(TOOLCHAIN_EXTERNAL_INSTALL_DIR) $(TAR_OPTIONS) - \
fi
endef
One can even wonder why the 'exclude=' couldn't be used for blackfin,
and why the --hard-dereference couldn't be used for non-blackfin. This
would make the only difference the strip-components.
Best regards,
Thomas

I agree this and other cleanups would make this file cleaner.
However Thomas is proposing a rather substantial change to a quite core
piece of Buildroot. So I would keep things as they are at a first step.
This allows to make the change to the package system withthe minimum
diffs, thus making it easier to spot any problems that might ariseif
the patches are committed to master.
When the whole thing will be tested for at least a few days by the
autobuilders, I think it would be ok to start cleanup and refactoring.
Just my two cents.

At first sight, hijacking the configure step to check toolchain settings
and the
install staging step to install into host and target does not look very
clean.
I think here we are pushing the package infrastructure a bit beyond what
it is
conceived for.
Nevertheless this it not a very dirty hack (just a bit) and makes the
whole file
a little simpler. Not to mention this unlocks new features, which is the
final
goalof the whole patchset, isn't it?
Overall I think the pros are stronger than the cons here. And extending the
package infra just to make this one file more polite wouldn't be worth
the effort,
I suppose. So:

The dependencies-source, dependencies-clean and dependencies-dirclean
targets are not needed, as long as 'dependencies' is not used in the

About that i've already sent a patch "package: add toolchain
dependency to inner-generic-package:
http://patchwork.ozlabs.org/patch/237887/
I will rebase and send the patch after i sent the v3 for the top-level
parallel make.

Seems right, but it should remove "toolchain" from being pulled in the
main Makefile. If all target packages already depend on it, there's no
longer a reason to have "toolchain" be a special case target handled by
the main Makefile (unless I'm missing something).
Best regards,
Thomas

You are right i will try to do that, if i remember correctly removing
the toolchain depency in the main makefile give some building issue,
maybe some non-package stuff still depends on it or at least on a part
of it like "prepare dirs dependencies".
Maybe the correct solution is to have as dependency a "base" target
without pulling the whole toolchain.
Best regards

I would really like to see this because one of my biggest 'annoyances'
with buildroot is that if do a "make clean" and then "make <package>",
the toolchain doesn't copy over automatically. I use this sequence of
commands to test that I have my dependancies correct when adding new
packages or just testing a specific package that it builds correctly.
Again this is just annoyance with a simple workaround but it is good
to see that I'm not the only person with this annoyance. Thanks Fabio
for attempting to fix this.

Is it too early to move toolchain/ to package/? Or there is a reason
to keep toolchain/ out of package/?

Well, we do have packages outside of package/, such as the kernel and
bootloaders. I believe it makes sense to keep the toolchain backends in
toolchain/. Besides, the toolchain-buildroot/ package is really just an
indirection for host-gcc-final. Only the toolchain-external/ package
really contains some real stuff.
Best regards,
Thomas
