The current test to verify if the toolchain uses musl or not is based on
checking if /lib/libc.so or /lib/libm.so exist in the sysroot. However,
some toolchains (notably Crosstool-NG ones) put these libraries in
/usr/lib/.
To fix this, build a minimal C program and check if the program
interpreter contains /lib/ld-musl.

TOOLCHAIN_EXTERNAL_READELF is defined to
$(TOOLCHAIN_EXTERNAL_CROSS)readelf$(TOOLCHAIN_EXTERNAL_SUFFIX), where
TOOLCHAIN_EXTERNAL_SUFFIX is .br_real for Buildroot
toolchains. However, this is bogus, because readelf is not wrapped by
the Buildroot toolchain wrapper, so "<arch>-readelf.br_real" never
exists.
Therefore, it should simply be defined as
$(TOOLCHAIN_EXTERNAL_CROSS)readelf. Currently,
TOOLCHAIN_EXTERNAL_READELF is not used anywhere, so it wasn't visible,
but a follow-up commit will make use of it.

Currently, `--version` option is used and later matched with a regex to get
the actual gcc version. There's a dedicated gcc option to do exactly that:
`-dumpversion`.
Also `--version` may return a string customised by a vendor that provides
the toolchain, which makes the current regex approach error prone. In
fact, this situation has been seen with a real customised toolchain.

Function copy_toolchain_sysroot, which is in charge of copying the relevant
bits from the external toolchain to the staging directory, performs an rsync
loop of various directories and excludes the pattern 'usr/lib/locale' with
the intention of skipping the directory <toolchain>/usr/lib/locale.
However, while this worked in the original commit, commit
5628776c4a broke it inadvertently. The
relevant part of the diff:
- rsync -au --chmod=Du+w --exclude 'usr/lib/locale' \
- $${ARCH_SYSROOT_DIR}/$$i $(STAGING_DIR)/ ; \
+ rsync -au --chmod=Du+w --exclude 'usr/lib/locale' \
+ --exclude lib --exclude lib32 --exclude lib64 \
+ $${ARCH_SYSROOT_DIR}/$$i/ $(STAGING_DIR)/$$i/ ; \
Notice how the source directory now contains a trailing slash, which impacts
the way the exclude rules are interpreted. Previously, when 'i' was 'usr',
the exclude of 'usr/lib/locale' would find a match. With the trailing slash,
there will never be a match, unless for a directory 'usr/usr/lib/locale'.
The right rule would have been '--exclude lib/locale'.
However, just that fix does not solve the problem in all cases, in
particular in the (common) case where ARCH_LIB_DIR is 'lib'. This is due
another change in that commit, changing the iterated values of the above
rsync:
- for i in etc $${ARCH_LIB_DIR} sbin usr ; do \
+ for i in etc $${ARCH_LIB_DIR} sbin usr usr/$${ARCH_LIB_DIR}; do \
Due to the fact that we rsync both 'usr' as 'usr/lib' (assuming ARCH_LIB_DIR
is 'lib') we need to add the correct exclude in both cases. But the exclude
is different for both. When i == 'usr', the correct exclude rule would be
'--exclude lib/locale' while when i == 'usr/lib' the correct rule would be
'--exclude locale'.
Since we would like to avoid separate cases for this, use the following
exclude: '--exclude locale/'. The trailing slash will make sure only
directories called 'locale' will match. The targeted directories are then
usr/lib/locale and usr/share/locale. The latter directory was not matched
originally, but it should not hurt changing that.

As discussed with Thomas Petazzoni, we can reduce the nesting level by early
returning on an invalid iteration.
I did not move the 'else' case (the common case) outside the if-else because
it would make the code less symmetrical and IMO makes it _less_ clear.

The handling of RPATH in cmake-3.7 has changed drastically, causing a
slew of build failures dues to libraries from the host being pulled in:
- domoticz : http://autobuild.buildroot.org/results/fd0/fd0ba54c7abf973691b39a0ca1bb4e07d749593a/
- freerdp : http://autobuild.buildroot.org/results/5d4/5d429d0e288754a541ee5d8be515454c5fccd28b/
- libcec : http://autobuild.buildroot.org/results/3f3/3f3593bab7734dd274faf5b5690895e9424cbb89/
- and so on...
The bug was reported upstream [0], which dismissed it altogether [1] as
being expected behaviour, quoting:
I don't think there is anything wrong with that change on its own.
It merely exposed some existing behavior in a new case.
Instead, upstream suggested in that same message that a platform
definition be used instead, quoting:
If a toolchain file specifies CMAKE_SYSTEM_NAME such that a custom
`Platform/MySystem.cmake` file is loaded then the latter can set
them as needed for the target platform.
So here we are doing so:
- we add a new platfom definitions that inherits from the Linux one,
then overrides the problematic settings;
- we change our toolchain file to use that platform instead;
- we tell cmake where to find additional modules, so that it can find
our custom platform file.
This has been tested to work in the following conditions:
- pre-installed host cmake, versions 3.5.1 (Ubuntu 16.04) and 3.7.2
(manually built)
- internal cmake, versions 3.6.3 (the current version as of this
patch) and 3.7.2 (with the followup patches).
Thanks to Jörg, Ben and Baruch for the help investigating the issue.
Special thanks to Jörg for handling the discussion with upstream and
pointing to the relevant messages! :-)

To be noted: Thomas suggested we set these directly in the toolchain
file. Unfortunately, wherever we put those settings in the toolchain
file, this does not work.

This reverts commit 76838f6341.
The commit referenced above explicitly states that the function was
copied as-is from the gcc source code at the time. And indeed that is
exactly how the function appeared in gcc in commit
e3e8c48c4a494d9da741c1c8ea6c4c0b7c4ff934.
However, our toolchain wrapper is "GPLv2 only", while the file this function
was copied from is "GPLv3 or later". As such we can't include that function
and still comply to both licenses.
Furthermore, the code is far from optimum.
Since this feature is not release-critical, revert it until we re-implement
it.

We currently support gcc as old as 4.3. However, Buildroot works
perfectly well with even older gcc versions (tested with 4.1). So we
can add an option BR2_TOOLCHAIN_EXTERNAL_GCC_OLD to support that. The
help text of this option is written with plenty of discouragement.
We use _OLD and not something like _PRE_4_3, because at some point we
will likely remove the 4.3 option and what would then require a name
change.
We don't set any _AT_LEAST option in this case because it's no use -
there is no lower bound on the version in this case. We therefore leave
BR2_TOOLCHAIN_GCC_AT_LEAST empty (the implicit default). When it is
empty, we don't do a version check at all in check_gcc_version
(previously we errored out when it was empty).

The toolchain-external-package infrastructure is just a copy of the
toolchain-external commands, replacing TOOLCHAIN_EXTERNAL by $(2)
and adding double-dollars everywhere.
toolchain-external itself is converted to a virtual package, but it
is faked a little to make sue the toolchains that haven't been
converted to toolchain-external-package yet keep on working.
The TOOLCHAIN_EXTERNAL_MOVE commands don't have to be redefined
for every toolchain-external-package instance, so that is moved
out into the common part of pkg-toolchain-external.mk.
The musl-compat-headers dependency stays in the toolchain-external
package itself.
The musl ld link is duplicated in the legacy toolchain-external and
the toolchain-external-package, because they have separate hooks.
The handling of TOOLCHAIN_EXTERNAL_BIN deserves some special attention,
because its value will be different for different
toolchain-external-package instances. However, the value only depends
on variables that are set by Kconfig (BR2_TOOLCHAIN_EXTERNAL_PREFIX
and BR2_TOOLCHAIN_EXTERNAL_DOWNLOAD) so it can easily be used in
the generic part. So we don't have to do anything specific for this
variable after all.

Rick Felker suggested[1] this hack as a workaround to musl libc conflict with
kernel headers:
The problem is linux/libc-compat.h, which should fix this, only works
on glibc, by design. See:
#ifndef _LIBC_COMPAT_H
#define _LIBC_COMPAT_H
/* We have included glibc headers... */
#if defined(__GLIBC__)
/* Coordinate with glibc netinet/in.h header. */
#if defined(_NETINET_IN_H)
If you patch it like this:
-#if defined(__GLIBC__)
+#if 1
then it should mostly work but it's still all a big hack. I think
that's what distros are doing. The problem is that the same header is
trying to do two different things:
1. Provide extra linux-kernel-API stuff that's not in the
libc/userspace headers.
2. Provide definitions of the standard types and constants for uClibc
and klibc, which don't have complete libc headers and rely on the
kernel headers for definitions.
These two uses really should be separated out into separate headers so
that the latter only get included explicitly by uClibc and klibc and
otherwise remain completely unused. But that would require coordinated
changes/upgrades which are unlikely to happen. :(
Upstream musl still evaluates[2][3] a permanent solution.
With this in place we can revert (at least) commits a167081c5d (bridge-utils:
fix build with musl) and e74d4fc493 (norm: add patch to fix musl build).

ARCH_SUBDIR is computed based on the value of ARCH_SYSROOT_DIR and
SYSROOT_DIR. For nested toolchains ARCH_SYSROOT_DIR is a subdir of
SYSROOT_DIR, so a sed command like this one...
sed -r -e "s:^${SYSROOT_DIR}(.*)/$:\1:"
...basically removes the leading SYSROOT_DIR part from ARCH_SYSROOT_DIR.
But, for side-by-side sysroot toolchains ARCH_SYSROOT_DIR and
SYSROOT_DIR are at the same level, so the above sed command doesn't
make any effect.
This patch therefore improves the calculation of ARCH_SUBDIR to
clearly handle the three possible cases:
- There is a single sysroot, or the selected architecture sysroot is
the main one (i.e SYSROOT_DIR == ARCH_SYSROOT_DIR). In this case,
ARCH_SUBDIR is empty.
- There are side-by-side sysroots, such as
SYSROOT_DIR=.../sysroot/mips-r2-hard/ and
ARCH_SYSROOT_DIR=.../sysroot/mipsel-r2-hard/.
- The arch-sysroot is nested, such as SYSROOT_DIR=.../sysroot and

On some architectures (namely x86-64), glibc may provide a libmvec
library since glibc 2.22, which programs built with gcc OpenMP support
might get linked to.
In order for these programs to work on the target, we need to copy
this library to the target filesystem.
This commit takes care of this for the external toolchain
situation. Note that libraries listed in TOOLCHAIN_EXTERNAL_LIBS are
silently ignored if they don't exist. Therefore, we don't need to have
any condition on the architecture or glibc version.

Some packages, like libbsd, use -isystem flags to provide so-called
overrides to the system include files. In this particular case, this
is used in a .pc file, then used by antoher package; pkgconf does not
mangle this path; and eventually that other package ends up using
/usr/include/bsd to search for headers.
Our current toolchain wrapper is limited to looking for -I and -L, so
the paranoid check does not kick in.
Furthermore, as noticed by Arnout, there might be a bunch of other
so-unsafe options: -isysroot, -imultilib, -iquote, -idirafter, -iprefix,
-iwithprefix, -iwithprefixbefore; even -B and --sysroot are unsafe.
Extend the paranoid check to be able to check any arbitrary number of
potentially unsafe options:
- add a list of options to check for, each with their length,
- iterate over this list until we find a matching unsafe option.
Compared to previously, the list of options include -I and -L (which we
already had) extended with -idirafter, -iquote and -isystem, but leaving
all the others noticed by Arnout away, until we have a reason for
handling them.

Current, we only display the path that causes the paranoid failure. This
is sufficient, as we can fail only for -I and -L options, and it is thus
easy to infer from the path, which option is the culprit.
However, we're soon to add a new test for the -isystem option, and then
when a failure occurs, we would not know whether it was because of -I or
-isystem. Being able to differentiate both can be hugely useful to
track down the root cause for the unsafe path.
Add two new arguments to the check_unsafe_path() function: one with the
current-or-previous argument, one to specify whether it has the path in
it or not. Print that in the error message, instead of just the path.

This reverts commit a0aa7e0e17 and reworks
the code to fix a major and potentially catastrophic bug when the
following conditions are met:
- The user has selected a "known toolchain profile", such as a Linaro
toolchain, a Sourcery CodeBench toolchain etc. People using "custom
toolchain profile" are not affected.
- The user has enabled BR2_TOOLCHAIN_EXTERNAL_PREINSTALLED=y to
indicate that the toolchain is already locally available (as
opposed to having Buildroot download and extract the toolchain)
- The user has left BR2_TOOLCHAIN_EXTERNAL_PATH empty, because his
toolchain is directly available through the PATH environment
variable. When BR2_TOOLCHAIN_EXTERNAL_PATH is non-empty, Buildroot
will do something silly (remove the toolchain contents), but that
are limited to the toolchain itself.
When such conditions are met, Buildroot will run "rm -rf /*" due to
TOOLCHAIN_EXTERNAL_INSTALL_DIR being empty.
This bug does not exist in 2016.05, and appeared in 2016.08 due to
commit a0aa7e0e17.
Commit a0aa7e0e17 removed the assignment
of TOOLCHAIN_EXTERNAL_SOURCE and TOOLCHAIN_EXTERNAL_SITE to empty, as
part of a global cleanup to remove such assignments that supposedly
had become unneeded following a fix of the package infrastructure
(75630eba22: core: do not attempt
downloads with no _VERSION set).
However, this causes TOOLCHAIN_EXTERNAL_SOURCE to be non-empty even
for BR2_TOOLCHAIN_EXTERNAL_PREINSTALLED=y configuration, with the
following consequences:
- Buildroot downloads the toolchain tarball (while we're saying the
toolchain is already available). Not dramatic, but clearly buggy.
- Buildroot registers a post-extract hook that moves the toolchain
from its extract directory (output/build/toolchain-external-.../ to
its final location in host/opt/ext-toolchain/). Before doing this,
it removes everything in TOOLCHAIN_EXTERNAL_INSTALL_DIR (which
should normally be host/opt/ext-toolchain/).
Another mistake that caused the bug is commit
b731dc7bfb ("toolchain-external: make
extraction idempotent"), which introduce the dangerous call "rm -rf
$(var)/*", which can be catastrophic if by mistake $(var) is
empty. Instead, this commit should have just used rm -rf $(var) to
remove the directory instead: it would have failed without consequences
if $(var) is empty, and the directory was anyway already re-created
right after with a mkdir.
To address this problem, we:
- Revert commit a0aa7e0e17, so that
_SOURCE and _SITE are empty in the pre-installed toolchain case.
- Rework the code to ensure that similar problems will no happen in the
future, by:
- Registering the TOOLCHAIN_EXTERNAL_MOVE hook only when
BR2_TOOLCHAIN_EXTERNAL_DOWNLOAD=y, since moving the toolchain is
only needed when Buildroot downloaded the toolchain.
- Introduce a variable TOOLCHAIN_EXTERNAL_DOWNLOAD_INSTALL_DIR which
is the path in which Buildroot installs external toolchains when it
is in charge of downloading/extracting them. Then, the
TOOLCHAIN_EXTERNAL_MOVE hook is changed to use this variable, which
is guaranteed to be non-empty.
- Replace the removal of the directory contents $(var)/* by removing
the directory itself $(var). The directory was anyway already
re-created if needed afterwards. Thanks to doing this, if $(var)
ever becomes empty, we will do "rm -rf" which will fail and abort
the build, and not the catastrophic "rm -rf /*".

musl provides neither sys/queue.h nor sys/cdefs.h. Those two headers are
however quite widely used in a lot of packages (though they should at
least not use cdefs.h which is only full of mostly-legacy macros, and
which is mostly an internal header of glibc and was never really meant to
be exposed to, and used by packages).
But we don't live in an ideal world, so a lot of packages break when
those two headers are missing.
We already took care of sys/queue.h with the netbsd-queue package. But
the need for cdefs.h is getting more and more pressing.
We rename the netbsd-queue package into musl-compat-headers, and we
make it install sys/queue.h (from NetBSD) and sys/cdefs.h (a minimalist
one we bundle in Buildroot). We can't use the cdefs.h from NetBSD
because it includes machine-dependent headers; instead we bundle a very
minimalistic one, that covers only what we need.

significant amount of space, and most users do not need
locales. Therefore, it makes more sense to default to purging locales,
in order to keep only a few useful ones rather than keeping them all.
It helps in providing a small filesystem size by default, and still
allows advanced users who really need locales to tune their
configuration.
As an example, a very basic system with just util-linux enabled (not
even Busybox) weights 11 MB, including 6.4 MB of locales. With this new
default, the generated system is only 4.2 MB.

The cairo package fails to build on some architectures:
BR2_TOOLCHAIN_HAS_LIBATOMIC is enabled, but libatomic is in fact not
available.
This happens because the gcc logic in libatomic/configure.tgt does not
recognize "uclinux" as a valid OS part of the target tuple, and
therefore it does not build libatomic.
The "uclinux" part of the tuple is used by Buildroot when
BR2_BINFMT_FLAT=y, so we make BR2_TOOLCHAIN_HAS_LIBATOMIC enabled only
if !BR2_BINFMT_FLAT.
It is worth mentioning that support for the uclinux tuple could most
likely very easily be added to gcc: it could rely on the generic
"posix" implementation of libatomic, which uses pthread locks,
available on all architectures where thread support is available.

this commit continues a series of updates of ARC tools.
This time we're updating tools to arc-2016.09-eng007 tag plus a
couple of fixes on top of it that will all make its way in the
next engineering build.
We hope this patch will cure most buildroot ARC failures as it
contains important fixes:
1) PIE fix. We have added PIE support to ARC toolchain at last.
So that should prevent breakage of many packages. As ARC now
supports PIE we remove ARC from BR2_TOOLCHAIN_SUPPORTS_PIE
exclusion in toolchain/Config.in file.
2) Assembler fix. This patch also have changes that fixes frequent
assembler failures, e.g.:
http://autobuild.buildroot.net/results/543/5430b902d900943a34c1888e7e410bd5df367bc2//
We still keep GDB as it is of arc-2016.03 release because there're some

Now that we have introduced the support for ARM no-MMU in Buildroot,
we need to update the dependencies of the musl external toolchain. It
supports only MMU-capable ARM cores, so it must depend on BR2_USE_MMU,
at least for the ARM platforms.

ARM big-endian is different from ARMv4/5/6 and ARMv7. Big-endian on
ARMv4/5/6 is BE-32 while big-endian on ARMv7 is BE-8, which are not
compatible.
Therefore, the musl big endian toolchain that is built for ARMv4
cannot work for ARMv7, it can only work for ARMv4/5/6.
This commit updates the musl toolchain dependency accordingly.

uClibc-ng does not support PIE for some architectures as
arc and m68k. It isn't implemented in the static linking case, too.
With musl toolchains you might have static PIE support with little
patching of gcc. Static linking for GNU libc isn't enabled in
buildroot. Fixup any package using special treatment of PIE.

The Codescape toolchain uses a sysroot layout that places them
side-by-side instead of nested like multilibs. A symlink is needed much
like for the nested sysroots which are handled in copy_toolchain_sysroot
but there is not enough information in there to determine whether the
sysroot layout was nested or side-by-side.
For the above reason plus the fact that this is the only toolchain
needing this, better to handle that symlink creation using a hook which
will be executed only when that toolchain is selected.

This reverts commit 9a1e9efe26.
Currently Codescape toolchains cannot be used to generate a big endian
root file system because the support for side by side sysroots is not
complete.
There is a patch [1] waiting in the queue which fixes the issue for the
current version of Codescape toolchains we have, but it will not work
for the next one that is coming. So, instead of messing more with the
toolchain infra I think it's better to handle these specific Codescape
toolchain's weirdness in hooks which won't affect others.

In 2a87b64 (toolchain-external: align library locations in target and
staging dir), copying the libraries from the sysroot to the target was
changed to a simple find-based solution.
To be sure that the staging directory was entered to find the libraries,
in case the variable was pointing to a symlink, the -L clause to find
was used.
However, that causes extraneous libraries to be copied over.
For example, a ct-ng toolchain would have this sysroot (e.g for an arm
32-bit toolchain):
.../sysroot/lib/
.../sysroot/lib32 -> lib
.../sysroot/lib64 -> lib
.../sysroot/usr/lib/
.../sysroot/usr/lib32 -> lib
.../sysroot/usr/lib64 -> lib
Which we would carry as-is to our own sysroot.
But then, in target, our skeleton creates the /lib/ and /usr/lib
directories, with the necessary lib32 or lib64 symlink pointing to it.
In this case, a lib32->lib symlink is created, but no lib64 symlink
since this is a 32-bit architecture.
To copy the required libraries from staging into target, we scan the
staging directory for all occurences of the required libraries, and copy
them over to target, keeping the same directory layout relative to the
sysroot.
For example:
.../sysroot/usr/lib/libfoo.so --> .../target/usr/lib/libfoo.so
.../sysroot/usr/lib32/libbar.so --> .../target/usr/lib32/libbar.so
.../sysroot/usr/lib64/libbuz.so --> .../target/usr/lib64/libbuz.so
So, when we copy over the libraries from our staging to the target
directory, the "find -L .../sysroot -name libblabla.so.*" would find
multiple instances of libblabla, each in the /usr/lib /usr/lib32 and
/usr/lib64 locations (they are all the exact same file, though).
Since we do have the /usr/lib32->lib symlink, all is OK (but there are
two copies going on, which could be avoided). However, since we do not
have the /usr/lib64->lib symlink, the /usr/lib64/ directory is created.
This was very difficult to observe, as no /lib64/ directory is created,
only the /usr/lib64/ one was. To top it off, this only happens with a
merged /usr, which does not seem like not a common case without systemd.
Since the reason to use -L was to be sure to enter our staging
directory, we just need to ensure that the path ends up with a slash, as
was already talked about in this thread:
http://lists.busybox.net/pipermail/buildroot/2016-April/159737.html
After further discussion, it turns out that the original patch came along
because of the confusion between output/staging (which is a symlink) and
$(STAGING_DIR) which expands to output/host/usr/<tupple>/sysroot (which is
never a symlink), so the symlink handling isn't really needed at all.

Don't enable SSP support on external toolchains just because they use
