Starting from 2012.03, the Linaro toolchains have separated the GCC
support libraries (libstdc++, libgcc_s) from the sysroot itself. So we
no longer have the case where all libraries are inside the sysroot, as
we had for all the previously supported toolchains.
Therefore, we add some logic to detect if such a separate directory is
used for GCC support libraries, and if it's the case, we make sure
that we take into account this directory when creating our own
sysroot, and when copying libraries to the target filesystem.

Linaro has just released a new pre-built toolchain, available as a
tarball, which is a pure toolchain (only the C library is
included). This makes this new Linaro 2012.01 toolchain usable in
Buildroot, so let's integrate the support for it.
In addition to simply adding the new external toolchain at the usual
locations, this patch allows need to adapt a few things to support
Linaro toolchains. Most toolchains store their libraries in the "lib/"
or "usr/lib" directories relative to the toolchain. Buildroot
toolchains on the other hand, store the libraries in the
"usr/<target-name>/lib" directory. And the Linaro toolchain has
choosen to use the "lib/<target-name>" directory. Therefore, this
patch adjust:
* The logic to search a particular library when that library needs to
be copied to the target directory
* The logic to deduce the sysroot directory from the libc.a file
location in the toolchain: removing "(usr/?)lib(64?)" is no longer
sufficient, we need to take into account the "lib/<target-name>/"
case.
Since the Linaro toolchain generates code for Cortex-A processors
only, the selection of this toolchain is limited to Cortex-A8 and
Cortex-A9.

When an external toolchain has multiple variants organized in
sub-directories, Buildroot only copies the selected sysroot and not
all sysroots. In order to make this work, Buildroot creates a symbolic
link of the name of the original selected sysroot to the main sysroot
to trick the compiler so that it finds its libraries at the expected
location.
I.e, if the toolchain as the following organization (example take on
the ARM CodeSourcery toolchain) :
. for ARMv5T
armv4 for ARMv4T
thumb2 for ARMv7-A/Thumb
and ARMv4T is selected, then Buildroot will copy the contents of
armv4t/ from the toolchain into its $(STAGING_DIR) and then create a
$(STAGING_DIR)/armv4t symbolic link to $(STAGING_DIR).
However, our logic to do so only works when there was one directory
level for multilib sysroots. But in the MIPS CodeSourcery toolchain
there are multiple levels. For example, the MIPS16 soft-float
little-endian sysroot variant is in mips16/soft-float/el/ compared to
the main sysroot.
This patch improves our logic to support this case. The logic is a bit
more complicated as we don't want to create a symbolic link to an
absolute path, but a symbolic link to a relative path, because we want
the host/ directory to be relocatable.

The IA32 Sourcery CodeBench toolchain has a relatively special
structure, with the following multilib variants:
* Intel Pentium 4, 32 bits, the multilib variant is in ./ relative to
the main sysroot, with the libraries in the lib/ directory.
* Intel Xeon Nocona, 64 bits, the multilib variant is in ./ relative
to the main sysroot, with the libraries in the lib64/ directory.
* Intel Atom 32 bits, the multilib variant is in atom/ relative to
the main sysroot, with the libraries in the lib/ directory.
* Intel Core 2 64 bits, the multilib variant is in core2/ relative to
the main sysroot, with the libraries in lib64/ directory.
So the first two variants are in the same sysroot, only the name of
the directory for the libraries is different.
Therefore, we introduce a new ARCH_LIB_DIR variable, which contains
either 'lib' or 'lib64'. This variable is defined according to the
location of the libc.a file for the selected multilib variant, and is
then used when copying the libraries to the target and to the staging
directory.
In addition to this, we no longer use the -print-multi-directory to
get the ARCH_SUBDIR, since in the case of the 64 bits variants of this
toolchain, it returns just '64' and not a real path. Instead, we
simply compute the difference between the arch-specific sysroot and
the main sysroot.
We also take that opportunity to expand the documentation on the
meaning of the different variables.

Newer versions of GDB need pthread debugging support if threads are
enabled, which is always the case for glibc but is a configure option
for uClibc.
We have solved this for internal toolchains by selecting the
BR2_PTHREAD_DEBUG option from the GDB selection if needed, but as this
option isn't available when ctng/external toolchains are used, mconf
prints ugly warnings and the build may fail if an external uClibc
toolchain without pthread debugging support is used.
Fix it by introducing 2 more hidden config options:
- BR2_TOOLCHAIN_HAS_THREADS_DEBUG
- BR2_TOOLCHAIN_HAS_THREADS_DEBUG_IF_NEEDED
The first tells us if the toolchain HAS pthreads debugging support,
and is checked by check_uclibc_feature in helper.mk for external uClibc
based toolchains.
The second tells us if the toolchain is ABLE TO provide pthreads debugging
support if threads are enabled, either because it's an internal toolchain
where we can force enable it or an external glibc/eglibc toolchain or
uClibc with the option enabled.
Crosstool-ng forcibly enables this support, so those will always work.
The preconfigured uClibc-based toolchains we have also all enable it.
Finally, show a comment if this isn't the case so the (external toolchain)
user knows why. This is placed outside the choice option, as menuconfig
has a bug where it doesn't show choice selections which only contain
comments.

The gdb tarballs have been re-released after a GPL compliance
issue was found:
http://sourceware.org/ml/gdb/2011-09/msg00030.html
So all versions were re-packaged.
In the process, an 'a' was appended to the version strings, and
unlike the binutils people, the gdb folks are not inclined in
providing legacy symlinks:
http://sourceware.org/ml/gdb/2011-09/msg00036.html
So, this patch fixes the issue by renaming version strings. It is to be
noted that, although the versions got bumped to include an 'a' at the end,
the directory contained in the tarball is still named after the version
string without the 'a'. For example:
- old version : 6.6
- new version : 6.6a
- tarball name : gdb-6.6a.tar.bz2
- directory name : gdb-6.6/
In fact, it does not pose any problem for buildroot, as the extract process
explicitly mkdirs the directory to extract into, *and* strips the first level
of the tree extracted from the tarball.

Bundled config files have architecture-specific values in them,
which may break if buildroot is configured with another architecture
that does not forcibly set these option.
For example, the bundled config files are for x86_64, and define:
CT_ARCH_TUNE="generic"
This comes from the BR2_GCC_TARGET_TUNE config option (in buildroot) that
is set accordingly to the selected (arch,sub-arch).
But if someone configures buildroot for, say, generic ARM, then the
BR2_GCC_TARGET_TUNE config option is not set, and the crosstool-NG backend
Makefile believes it should not be pushed down to the crosstool-NG config
file.
BUT...
The crosstool-NG backend Makefile can not forcibly push BR2_GCC_TARGET_TUNE
down to the CT-NG config file. If BR2_GCC_TARGET_TUNE is empty, the user can
still set CT_ARCH_TUNE by running ctng-menuconfig.
The backend Makefile already passes such values only if they are set.
In the end, we can't push options as-is to the crosstool-NG config, but we
MUST provide sane bundled config files, which this patch does.

Peter on IRC reported some build failures for different targets.
They were of two kinds:
- missing/unknown stack unwinding support
- missing *_chk functions
The first is about configure not being able to automagically determine
if stack unwinding support is available for the target. The second is
about fortified build forgetting to build the fortified functions.
This applies to both glibc and eglibc.
After some discussions on IRC with Jacmet, it appears that we can
safely assume both of the following:
- virtually all targets of buildroot will have stack unwinding support
- we do not care about fortified builds (so far)
So, update the bundled crosstool-NG .config file to saner defaults:
- force unwind support
- disable fortified builds

Add a simple toolchain wrapper for external toolchains, which forces the

With this in place the external toolchain behaves similar to the internal

toolchain is usable outside buildroot without having to pass any special
compiler flags.
Also adjust the downloadable external toolchain support to install under

telling Buildroot what the configuration of the toolchain is. In order
to make sure that the selection is correct, we already perform checks
against the configuration of the uClibc in the selected external
toolchain. This commit adds the check for thread support.

The selection of linuxthreads, linuxthreads old or NPTL doesn't make a
lot of sense for external toolchains. So, instead, we :
* Introduce an hidden BR2_TOOLCHAIN_HAS_THREADS option, which must be
selected by toolchain specific options when thread support is
available. Package needing to test thread support should use this
option.
* Move the none/linuxthreads/linuxthreads old/NPTL selection to
Buildroot internal toolchain configuration.
* Add an option in external toolchain to tell if thread support is
available or not in the external toolchain. We assume that glibc
without threads is not possible, as Ulrich Drepper said in
http://sourceware.org/ml/libc-alpha/2005-08/msg00091.html
ffmpeg, dmalloc and openvpn are fixed to use the new
BR2_TOOLCHAIN_HAS_THREADS option. For openvpn, --enable-threads=posix
is no longer used, as the configure script doesn't even understand
this option.

Instead of having BR2_GCC_CROSS_CXX and BR2_INSTALL_LIBSTDCPP, with
BR2_GCC_CROSS_CXX not being visible (and therefore being useless),
let's just keep BR2_INSTALL_LIBSTDCPP to enable C++ in the toolchain
and install C++ libraries on the target.
We also take that opportunity to make BR2_INSTALL_LIBSTDCPP an hidden
option, which is selected by an option in Buildroot toolchain support
or an option in External toolchain support, just as we did for other
toolchain features.
Some work definitely remains to be done :
- The name BR2_INSTALL_LIBSTDCPP is ugly, but we keep it for the
moment in order to avoid changing all packages.
- We should clarify the other language-related options (Fortran,
Java, Objective-C, etc.).

Instead of letting the user define all the details of his external
toolchain, we define a set of profiles for well-known external
toolchains (CodeSourcery ones only at the moment, can easily be
extended with other toolchains).
Once a profile has been choosen, the user is offered the choice of
either letting Buildroot download and install the external toolchain,
or (as before) to tell Buildroot where the toolchain is installed on
the system.
We of course provide a "custom profile", through which the user can
configure Buildroot to use a custom external toolchain for which no

Turn BR2_LARGEFILE, BR2_INET_IPV6, BR2_INET_RPC, BR2_USE_WCHAR,
BR2_ENABLE_LOCALE and BR2_PROGRAM_INVOCATION into hidden options.
Then, for Buildroot toolchains, external toolchains and Crosstool-NG
toolchains, provide visible options that selects the hidden options.
This allows :
* To show a different label and help text in the case of Buildroot
toolchain (do you want to enable feature X ?) and in the case of
external toolchain (is feature X available in your toolchain ?)
* To not show any option when a glibc external toolchain is selected
(since glibc is assumed to support all of largefile, IPv6, RPC,
WCHAR, locale and program invocation) and have them all selected in
that case.
There is some amount of duplication between Buildroot toolchain config
options and Crosstool-NG toolchain config options, because kconfig
doesn't allow to source the same Config.in file twice (even if under
mutually exclusive conditions). This duplication is more readable that
the hack that consists in splitting files in multiple pieces.
However, this commit changes the name of the options visible in the
configuration interface, so existing .config files will have to be
updated accordingly.

This commit solves bug #1051. The problem in this bug in that WebKit
compiles a sample C program, which uses WebKit. As WebKit is written
in C++, even though the program it built with CROSS-gcc, it must be
linked with libstdc++. However, CROSS-gcc can't find the libstdc++ has
it's hidden inside <sysroot>/<tuple>/lib.
Therefore, this commit creates a symbolic link <sysroot>/<tuple>/lib
-> <sysroot>/lib before running the CROSS-gcc installation. While this
may look like a hack, this is the solution used by both Crosstool-NG
and OpenWRT.
Moreover, with this symbolic link in place, I think bug #1741 may also
be solved. The problem in this bug is that the linker tries to link
against /lib/libc.so.0. This is due to the fact that the linker finds
a libc.so script file in the original toolchain location and not
inside the copy of the toolchain sysroot in $(STAGING_DIR). As the
script file is found outside of the current toolchain sysroot, ld
considers the script has non-sysrooted, and therefore doesn't prefix
all paths found in the script file (such as /lib/libc.so.0) with the
sysroot path, leading to the failure.
So, in details, this commit :
* Adds a BR2_ARCH_IS_64 invisible config knob that is used to know if
the arch is a 64 bits architecture or not.
* Creates the <sysroot>/<tuple>/lib -> <sysroot>/lib symbolic link,
and the <sysroot>/<tuple>/lib64 -> <sysroot>/lib64 symbolic link if
needed.
* Fixes the external toolchain sysroot detection code so that the
'sed' replacement is done *after* the readlink -f evaluation.
I have tested this by building ARM, x86 and x86_64 toolchains with
Buildroot, and then use these toolchains as external toolchains to
build a full X.org/Gtk/WebKit/Midori stack. I have also done a
complete ARM Buildroot internal toolchain build with the same full
X.org/Gtk/WebKit/Midori stack.

Until now, the function copy_toolchain_lib_root was copying a given
library to the target filesystem by assuming that it should be at the
same place it was in the toolchain sysroot.
However, with Buildroot hiding libstdc++ in
/usr/<target-name>/lib(64), this isn't correct, and it is probably
safer not to rely on the toolchain organization anyway.
Therefore :
* Instead of having a single EXTERNAL_LIBS variable, we now have
LIB_EXTERNAL_LIBS and USR_LIB_EXTERNAL_LIBS, which respectively
list the libraries that should be copied to /lib and /usr/lib. As
of today, only libstdc++ is part of the second list.

Create lib64 -> lib and usr/lib64 -> usr/lib symbolic links in the

toolchains such as the Crosstool-NG toolchains, for which the path to
the dynamic loader and other libraries is /lib64, but the libraries
are stored in /lib.

For the detection of the ARCH_SYSROOT_DIR (which contains the C
library variant specific to the compiler flags), we used to pass only
the -march argument instead of the full TARGET_CFLAGS. This was done
because TARGET_CFLAGS contains --sysroot, and we don't want to tell
here the compiler which sysroot to use, because we're specifically
asking the compiler where the *normal* arch sysroot directory is.
Unfortunately, there are some multilib variants that aren't decided
only based on -march, but also on -msoft-float or other compiler
flags. Therefore, we take the opposite approach: pass the full
TARGET_CFLAGS, from which we have stripped the --sysroot option.
For example, this allows a PowerPC CodeSourcery toolchain, on which
we're using the soft-float multilib variant, to work properly as an
external toolchain.

Having a BR2_NEEDS_GETTEXT option, as introduced by
54d64798e1 isn't sufficient to express
the different kind of dependencies on gettext.
This commit, based on an idea by Peter Korsgaard, introduces two
different options :
* BR2_NEEDS_GETTEXT, which is true as soon as the toolchain doesn't
provide gettext itself (i.e, when the toolchain is uClibc based, be
it an internal or external toolchain)
* BR2_NEEDS_GETTEXT_IF_LOCALE, which is true when the toolchain
doesn't provide gettext *and* locale support has been enabled in
Buildroot.
A following commit adds some documentation that details how these
configuration variables should be used by packages.

When using an external toolchain that uses the glibc or eglibc C
libraries, compiling a separate gettext and libintl is not needed and
is even a source of confusion, causing build failures. These build
failures are due to the fact that when libintl is compiled, it
replaces the C library libintl.h by its own, which does #define
gettext libintl_gettext. Then, when packages want to use gettext,
autoconf realize that gettext is available in the C library and
therefore do not add -lintl to the LDFLAGS, causing the build failure
because the program has been compiled to use libintl_gettext but this
function is not available.
Therefore, we should only use gettext if a uClibc internal toolchain
or a uClibc external toolchain. If an external glibc toolchain is
used, gettext shouldn't be used.
In order to implement that, we introduce the BR2_NEEDS_GETTEXT option,
which is hidden to the user, and whose value is computed automatically
from the rest of the configuration.

When building libxcb, the variable XCBPROTO_XCBPYTHONDIR must point to
the location where the Python modules needed to run the c_client.py
program are installed. The path
$(STAGING_DIR)/usr/lib/python2.6/site-packages was hardcoded. However,
it doesn't work when the version of Python installed on the host is
Python 2.5.
Therefore, add a little bit of magic to compute the host Python
version.
We also verify that Python is available on the host, as we don't build
it in Buildroot.

Multilib toolchains provide different versions of the base libraries
for different architecture variants. For example, the ARM Codesourcery
toolchain provides base libraries for ARMv5 (default), ARMv4t and
Thumb2.
Depending on the -march= argument passed to gcc, the sysroot used by
the compiler is therefore different. This means that the sysroot
location in CROSS-gcc -v cannot be used. Instead, we must use
CROSS-gcc -print-sysroot when available and fall back to the old way
if unavailable.
Moreover, we cannot simply copy the full sysroot as we used to do,
because the sysroot organization of multilib toolchain is more
complicated. In Codesourcery toolchains, we have :
/
etc -- for ARMv5
lib -- for ARMv5
sbin -- for ARMv5
usr -- for ARMv5 (includes headers)
armv4t
etc -- for ARMv4t
lib -- for ARMv4t
sbin -- for ARMv4t
usr -- for ARMv4t (no headers!)
thumb2
etc -- for Thumb2
lib -- for Thumb2
sbin -- for Thumb2
usr -- for Thumb2 (no headers!)
So we have the default ARMv5 architecture variant that is installed in
the main directory, and we have subdirectories for the ARMv4t and
Thumb2 architecture variants.
Copying the full sysroot to the staging directory doesn't work. All
our packages are based on the fact that they should install libraries
in staging/usr/lib. But if ARMv4t is used, the compiler would only
look in staging/armv4t/usr/lib for libraries (even when overriding the
sysroot with the --sysroot option, the multilib compiler suffixes the
sysroot directory with the architecture variant if it matches a
recognized one).
Therefore, we have to copy only the sysroot that we are interested
in. This is rendered a little bit complicated by the fact that the
armv4t and thumb2 sysroot do not contain the headers since they are
shared with the armv5 sysroot.
So, this patch :
* Modifies how we compute SYSROOT_DIR in order to use -print-sysroot
if it exists. SYSROOT_DIR contains the location of the main sysroot
directory, i.e the sysroot for the default architecture variant.
* Defines ARCH_SUBDIR as the subdirectory in the main sysroot for the
currently selected architecture variant (in our case, it can be
".", "armv4t" or "thumb2"). ARCH_SYSROOT_DIR is defined as the full
path to the sysroot of the currently selected architecture variant.
* Modifies copy_toolchain_lib_root (which copies a library to the
target/ directory) so that libraries are taken from
ARCH_SYSROOT_DIR instead of SYSROOT_DIR. This ensures that
libraries for the correct architecture variant are properly copied
to the target.
* Modifies copy_toolchain_sysroot (which copies the sysroot to the
staging/ directory), so that it copies the contents of
ARCH_SYSROOT_DIR, and if needed, adds the headers from the main
sysroot directory and a symbolic link (armv4t -> . or thumb2 -> .)
to make the compiler believe that its sysroot is really in armv4t/
or thumb2/.
Tested with Codesourcery 2009q1 ARM toolchain, Crosstool-NG ARM glibc
and ARM uClibc toolchains.

The copy_toolchain_lib_root function was making the assumption that
all libraries were stored inside the /lib directory of the sysroot
directory. However, this isn't true for certain toolchains,
particularly for the libstdc++ library.
The function is therefore reworked to find the library and its related
symlink either in /lib or /usr/lib in the sysroot, and copies it at
the same location in the target directory.

Since BR2_RECENT was enabled by default, we do not want entries marked

Therefore, all the entries marked BR2_RECENT are converted as

BR2_DEPRECATED to some of them. But at least, this commit doesn't

The toolchains built with buildroot use specially crafted paths for their
sysroot and prefix. Fix that by asking gcc where it finds a file we
know by relative path to the sysroot.
This has the side effect of greatly simplifying the sysroot detection
in every cases tested so far (BR toolchains, CT-NG toolchains, and
CodeSourcery toolchains).
Fixes bug #851.
