Peter Korsgaard c24faa81e8 Makefile: release: really drop build/docs from release tarball
Commit 15cb98769e (release: remove manual build files from release
tarballs) tried to remove the temporary files from the manual build from the
release tarball, but manual-clean only removes build/docs/manual and leaves
build/docs in the tarball.

Instead use 'make clean' to completely remove the build directory from the
tarball.

Yann E. MORIN 870f37fe04 core: add make-based full-dependency list
Currently, when we need to build the full dependency graph, we call make
to show the list of packages (make show-targets), and then call it again
and again iteratively while it returns new packages.

Since calling make will parse the whole set of our Makefiles, this takes
quite a bit of time (~4s each here), and the total can get pretty long.

However, make being make, already builds the whole dependency tree
information, so we can just ask for it.

Add a new top-level rule 'show-dependency-tree' that displays the whole
set of dependencies for all packages. For each package, its name, type
and version is displayed, then all the direct, first-level dependencies
are dumped. We choose a format that is not unlike the dot-graph format,
because it is both easy to read as a human, and easy to parse as a
machine:

    foo: target 1.2.3
    foo -> bar host-meh
    bar: target virtual
    bar -> buz
    buz: target 2.3.4
    buz ->
    host-meh: host virtual
    host-meh -> host-bleark
    host-bleark: host 3.4.5
    host-bleark ->
    rootfs-meh: host
    rootfs-meh -> host-bleark

To be noted: rootfs are currently reported as if they were 'host'
packages, to stay aligned with how graph-depends currently treats them.
Ideally, graph-depends could be enhanced to recognise them separately,
but that is another story.

For just plain defconfig, which is about the smallest config we can have
with an internal toolchain, we already have a seven-fold improvement
(with the graph-depends rule modified to not run the pdf generation, to
be able to just compare the tree generation):

    $ time make graph-depends
    real    0m27.344s
    $ time make show-dependency-tree
    real    0m3.848s

>From defconfig, C++, wchar, locales, ssp, and allyespackageconfig,
tweaked for even more packages (qt5 not qt4, luajit to avoid multi
providers, etc...), the timings are (graph-depends still modified to
not generate the pdf):

    $ time make graph-depends
    real    1m56.459s
    $ time make show-dependency-tree
    real    0m5.748s

There. I don't think those numbers need any explanation whatsoever;
they do speak on their own. OK, for maths sake, the ratio is about
twenty-fold. So, "yeah", I guess... ;-)

Arnout Vandecappelle (Essensium/Mind) fd5bd12379 Makefile: printvars: don't print anything when VARS is not set
Using 'make printvars' for printing all variables is not very useful.
E.g. all macros will output some bogus value. In addition, the same can
be achieved with 'make -p'.

We can simply remove the condition on $(VARS). If VARS is not set, the
filter expression will be empty which matches nothing, so nothing is
printed.

Note that the old behaviour can still be achieved with:
make printvars VARS=%

Update the 'make help' text to match the new behaviour.

Carlos Santos 0c96bda11e Makefile: allow rootfs overlays to override symbolic links
Since commit 0db34529f4 we use rsync with the --keep-dirlinks option to
prevent overlays from accidentally overwriding /{usr,bin,sbin,lib} links
when BR2_ROOTFS_MERGED_USR option is enabled. Unfortunately this also
prevents replacing a symlink by a directory on purpose (e.g. /var/log,
to persist system logs).

Steps to reproduce:

- enable BR2_ROOTFS_MERGED_USR and BR2_PACKAGE_SKELETON_INIT_SYSV
- mkdir some_path/rootfs-overlay/var/log
- enable BR2_ROOTFS_OVERLAY="some_path/rootfs-overlay"
- run 'make'
- 'target/var/log' is still a symlink to '../tmp', not a directory

The --keep-dirlinks option can be dropped, since we run sanity checks
on overlays. Now the rsync invocation is identical to the SYSTEM_RSYNC
logic we have in system/system.mk, so use that variable.

Joel Carlson 8fed162987 core/sdk: don't mangle symlinks with '.' or '..' at start
The current transform changes any '.' at the start of a filename to
$(BR2_SDK_PREFIX). This also applies to the target of a symlink, when
it is relative.

We thus might end up with something like:
    $(BR2_SDK_PREFIX)/bin/aarch64-linux-gnu-ar ->
    $(BR2_SDK_PREFIX)./opt/ext-toolchain/bin/aarch64-linux-gnu-ar

when it should be:
    $(BR2_SDK_PREFIX)/bin/aarch64-linux-gnu-ar ->
    ../opt/ext-toolchain/bin/aarch64-linux-gnu-ar

We fix that by making sure we always remove a known prefix, i.e. we
remove the path to host dir. The obvious solution would be to cd into
$(HOST_DIR)/.. , then tar ./host/ and finally use a --transfrom pattern
as 's,^\./$(notdir $(HOST_DIR)),$(BR2_SDK_PREFIX)'.

Since $(HOST_DIR) can point to a user-supplied location, we don't know
very well how the pattern may patch.

Instead, we cd into / and tar the full path to $(HOST_DIR).

Since tar removes any leading '/', it would spurr a warning message,
which is annoying. So we explicitly remove the leading '/' from
$(HOST_DIR) when we tar it.

Finally, we transform all filenames to replace a leading $(HOST_DIR)
(without a leading /) to the prefix to use.

John Keeping e5e0f637ab Makefile: respect strip exclusions for special libraries
ld-*.so and libpthread*.so* are not stripped in the same way as other
binaries because some applications need symbols in these libraries in
order to operate correctly.

However, the special handling for these binaries ignores the usual
BR2_STRIP_EXCLUDE_* rules so it is not possible to build an image which
has debugging symbols in these binaries.

Pull out the common find functionality so that we can build two find
commands that re-use the common exclusion rules.

will need to define TARGET_DIR in a different way depending on the

Adam Duskett bbf32a77ec utils/test-pkg: force checking dependencies
Currently, if a user runs "make" while specifying a specific package
(IE: make -p foo),  the Makefile logic skips checking to see if all the
dependencies are selected in the specified packages config file. This behavior
is useful to test simple packages which do not have "complex" dependencies.

However; if a developer uses test-pkg -p ${package_name} to check their package,
the package may pass all the checks, but would have otherwise failed with a
simple "make" because the developer may have failed to add a select line in
packages config file, even if there is a new dependency in the packages
Makefile.

Pass the environment variable "BR_FORCE_CHECK_DEPENDENCIES"  to the Makefile in
the test-pkg script,  and check it's value in the Makefile. If the value is
"YES" force checking for dependency issues.

Ricardo Martincoski e7e30455ef Makefile: offload .gitlab-ci.yml generation
GitLab has severe limitations imposed to triggers.
Using a variable in a regexp is not allowed:
|    only:
|        - /-$CI_JOB_NAME$/
|        - /-\$CI_JOB_NAME$/
|        - /-%CI_JOB_NAME%$/
Using the key 'variables' always lead to an AND with 'refs', so:
|    only:
|        refs:
|            - branches
|            - tags
|        variables:
|            - $CI_JOB_NAME == $CI_COMMIT_REF_NAME
would make the push of a tag not to trigger all jobs anymore.
Inheritance is used only for the second level of keys, so:
|.runtime_test: &runtime_test
|    only:
|        - tags
|tests.package.test_python_txaio.TestPythonPy2Txaio:
|    <<: *runtime_test
|    only:
|        - /-TestPythonPy2Txaio$/
would override the entire key 'only', making the push of a tag not to
trigger all jobs anymore.

So, in order to have a trigger per job and still allow the push of a tag
to trigger all jobs (all this in a follow up patch), the regexp for each
job must be hardcoded in the .gitlab-ci.yml and also the inherited
values for key 'only' must be repeated for every job.
This is not a big issue, .gitlab-ci.yml is already automatically
generated from a template and there will be no need to hand-editing it
when jobs are added or removed.

Since the logic to generate the yaml file from the template will become
more complex, move the commands from the main Makefile to a script.

Using Python or other advanced scripting language for that script would
be the most versatile solution, but that would bring another dependency
on the host machine, pyyaml if Python is used. So every developer that
needs to run 'make .gitlab-ci.yml' and also the docker image used in the
GitLab pipelines would need to have pyyaml pre-installed.
Instead of adding the mentioned dependency, keep using a bash script.

While moving the commands to the script:
 - mimic the behavior of the previous make target and fail on any
   command that fails, by using 'set -e';
 - break the original lines in one command per line, making the diff for
   any patch to be applied to this file to look nicer;
 - keep the script as simple as possible, without functions, just a
   script that executes from the top to bottom;
 - do not perform validations on the input parameters, any command that
   fails already makes the script to fail;
 - do not add an usage message, the script is not intended to be called
   directly.

This patch does not change functionality.

Thomas Petazzoni beef2b4ab8 Makefile: define TARGET_DIR_WARNING_FILE relative to TARGET_DIR
In commit 7e9870ce32 ("core: introduce
intermediate BASE_TARGET_DIR variable"), the definition of
TARGET_DIR_WARNING_FILE was changed to use $(BASE_TARGET_DIR) instead
of $(TARGET_DIR).

However, this change is incompatible with per-package directories, and
is in fact not needed.

With per-package directories, using $(BASE_TARGET_DIR) means that
TARGET_DIR_WARNING_FILE is
output/target/THIS_IS_NOT_YOUR_ROOT_FILESYSTEM. Due to this, when
skeleton-init-common or skeleton-custom attempt to install it, it
fails, because it should be installed to their package per-package
target directory, and not the global output/target directory that doesn't
exist yet. The failure looks like this:

/usr/bin/install -m 0644 support/misc/target-dir-warning.txt /home/thomas/projets/buildroot/output/target/THIS_IS_NOT_YOUR_ROOT_FILESYSTEM
/usr/bin/install: cannot create regular file '/home/thomas/projets/buildroot/output/target/THIS_IS_NOT_YOUR_ROOT_FILESYSTEM': No such file or directory
make[1]: *** [package/pkg-generic.mk:336: /home/thomas/projets/buildroot/output/build/skeleton-init-common/.stamp_target_installed] Error 1

TARGET_DIR_WARNING_FILE is used in three places:

 - In skeleton-custom.mk and skeleton-init-common.mk, where as
   explained above, using $(TARGET_DIR) fixes the use of
   $(TARGET_DIR_WARNING_FILE) in the context of per-package target
   directories.

 - In fs/common.mk, where it is used as argument to $(notdir ...) to
   retrieve just the name of the warning file. So in this case, we
   really don't care about the path of the file, just its name.

Thomas Petazzoni d0f4f95e39 Makefile: rework main directory creation logic
In the current code, the creation of the main output directories
(BUILD_DIR, STAGING_DIR, HOST_DIR, TARGET_DIR, etc.) is done by a
global "dirs" target. While this works fine in the current situation,
it doesn't work well in a context where per-package host and target
directories are used.

For example, with the current code and per-package host directories,
the output/staging symbolic link ends up being created as a link to
the per-package package sysroot directory of the first package being
built, instead of the global sysroot.

This commit reworks the creation of those directories by having the
package/pkg-generic.mk code ensure that the build directory, target
directory, host directory, staging directory and binaries directory
exist before they are needed.

Two new targets, host-finalize and staging-finalize are added in the
main Makefile to create the compatibility symlinks for host and
staging directories. They will be extended later with additional logic
for per-package directories.

Thanks to those changes, the global "dirs" target is entirely removed.

As we are going to move to per-package SDK, the location of CCACHE and
therefore the definitions of HOSTCC and HOSTCXX need to be evaluated

value of HOST_DIR changes from one package to the other.

Therefore, we need to change from := to =.

In addition, while doing A := $(something) $(A) is possible, doing A =
$(something) $(A) is not legal. So, instead of defining HOSTCC in
terms of the current HOSTCC variable, we re-use HOSTCC_NOCCACHE
instead.

Yann E. MORIN 3950e69dad core: support host gcc of the future
When we do a release, we know only of a set of gcc versions that the
host may have. But in the future, distributions with newer gcc versions
may show up.

Currently, we do not recognise those versions, and thus we do as if they
were older than the oldest we know of. This means that a set of packages
become unselectable, when they should be.

We fix that by capping the detected version to the highest we know of.

To update the .gitlab-ci.yml file, we run run-tests -l to list all the
tests and post-process the output in a format suitable for
.gitlab-ci.yml. However, in a pipeline, it is the last command that
gives the return value. In addition, we have to redirect stderr of
run-tests -l because nose2 prints the tests on stderr, not stdout. Thus,
when run-tests -l fails, the update of .gitlab-ci.yml silently succeeds
but no tests are included in the .gitlab-ci.yml.

To fix this, set the pipefail option. This is bash-specific, but our
Makefile ascertains that we are running with bash as the shell (if bash
is available, but if it is not, dependencies.sh will error out). The
error message is still invisible, but at least make will fail.

Yann E. MORIN 7007dc2bc9 core: detect and reject build paths which contain an '@'
gcc does not build when the srcdir path contains a '@', because that
path is then substitued in a texi file as argument to an @include
directive. But then, the '@' in the path will start a command evaluation
of its own, thus breaking the build. For example, with a $(O) path set
to /home/ymorin/dev/buildroot/O/to@ti :

    perl ../../gcc/../contrib/texi2pod.pl ../../gcc/doc/invoke.texi > gcc.pod
    ../../gcc/doc/invoke.texi:1678: unknown command `ti'
    ../../gcc/doc/invoke.texi:1678: @include: could not find /home/ymorin/dev/buildroot/O/to/build/host-gcc-initial-7.3.0/build/gcc/../../gcc/../libiberty/at-file.texi

Mark Corbin 9b3d52b400 arch: add support for RISC-V 64-bit (riscv64) architecture
This enables a riscv64 system to be built with a Buildroot generated
toolchain (gcc >= 7.x, binutils >= 2.30, glibc only).

This configuration has been used to successfully build a qemu-bootable
riscv-linux-4.15 kernel (https://github.com/riscv/riscv-linux.git).

Mark Corbin bd0640a213 arch: allow GCC target options to be optionally overwritten
The BR2_GCC_TARGET_* configuration variables are copied to

modified or overwritten by architecture specific makefiles.

All makefiles must use the new GCC_TARGET_* variables instead
of the BR2_GCC_TARGET_* versions.

Trent Piepho b8d0aadc6d Makefile: fix issue with printvars executing giant shell command
The underlying problem is that $(foreach V,1 2 3,) does not evaluate to
an empty string.  It evaluates to "  ", three empty strings separated by
whitespace.

A construct of this format, with a giant list in the foreach, is part of
the printvars command.  This means that "@:$(foreach ....)", which is
intended to expand to a null command, in fact expands to "@:       "
with a great deal of whitespace.  Make chooses to execute this command
with:
    execve("/bin/sh", ["/bin/sh", "-c", ":       "]

But with far more whitespace.  So much that it can exceed shell command
line length limits.

This solution is to move the foreach to another step in the recipe.  The
"@:" is retained as the first line so the recipe is not Empty, which
would cause a change in make behavior when make builds the target.  The
2nd line, all whitespace, will be skipped by make.

Yann E. MORIN c32ad51cbf core/sdk: generate the SDK tarball ourselves
Currently, the wording in the manual instructs the user to generate a
tarball from "the contents of the +output/host+ directory".

This is pretty confusing, because taken literally, this would amount to
running a command like:

    tar cf my-sdk.tar -C output/host/ .

This creates a tarbomb [0], which is very bad practice, because when
extracted, it creates multiple files in the current directory.

What one really wants to do, is create a tarball of the host/ directory,
with something like:

    tar cf my-sdk.tar -C output host/

However, this is not much better, because the top-most directory would
have a very common name, host/, which is pretty easy to get conflict
with when it gets extracted.

So, we fix that mess by giving the top-most directory a recognisable
name, based on the target tuple, which we also use as the name of the
archive (suffixed with the usual +.tar.gz+.) We offer the user the
possibility to override that default by specifying the +BR2_SDK_PREFIX+
variable on the command line.

Since this is an output file, we place it in the images/ directory.

As some users expressed a very strong feeling that they do not want to
generate a tarball at all, and that doing so would badly hurt their
workflows [1], we actually prepare the SDK as was previously done, but
under the new, intermediate rule 'prepare-sdk'. The existing 'sdk' rule
obviously depend on that before generating the tarball.

We choose to make the existing rule to generate the tarball, and
introduce a new rule to just prepare the SDK, rather than keep the
existing rule as-is and introduce a new one to generate the tarball,
because it makes sense to have the simplest rule do the correct thing,
leaving advanced, power users use the longest command. If someone
already had a wrapper that called 'sdk' and expected just the host
directory to be prepared, then this is not broken; it just takes a bit
longer (gzip is pretty fast).

Update the manual accordingly.

Thomas Petazzoni 1290241dc6 Makefile: introduce check-package target
The snippet of code that runs a check-package on all
.mk/.hash/Config.in files is currently only available within
.gitlab-ci.yml, and isn't immediately and easily usable by Buildroot
users. In order to simplify this, this commit introduces a top-level
"check-package" make target that implements the same logic. The
.gitlab-ci.yml file is changed to use "make check-package".

Since this target is oriented towards Buildroot developers, we
intentionally do not clutter the already noisy "make help" text with
this additional make target.

Arnout Vandecappelle (Essensium/Mind) 27aa7ae618 Makefile: help: BR2_DEFCONFIG for defconfig must be on command line
The help text says that BR2_DEFCONFIG will be used as input, but a
BR2_DEFCONFIG specified in the existing .config file will *not* be
used. So say explicitly that it must be specified on the command line.
Note that both "BR2_DEFCONFIG=... make defconfig" and
"make defconfig BR2_DEFCONFIG=..." will work.

While we're at it, add a semicolon to separate the two statements.

Note that this overflows the help text beyond 80 characters, but that
is already the case in many other lines.
