For the moment, we probably don't want to have several versions of
uClibc-ng supported at the same time. In preparation to the bump of
uClibc-ng to 1.0.1, this commit gets rid of the version number from
the uclibc-ng config option so that we don't have to rename this
option over and over again each time a new uClibc-ng release is
made. This would be annoying in terms of Config.in.legacy handling.
Since the option BR2_UCLIBC_NG_VERSION_1_0_0 has never been part of
any Buildroot release, we don't have to add anything to
Config.in.legacy.

There is no need to warn the user about selecting an inappropriate

can be selected.
Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
uClibc-ng does not support linuxthreads or linuxthreads.old on
architectures that have NPTL support. This creates another complicated
dependency: dependeing on the uClibc version being used, not the same
thread implementations are available.
In order to handle this situation, this patch introduces three hidden
booleans:
- BR2_UCLIBC_VERSION_SUPPORTS_LINUXTHREADS
- BR2_UCLIBC_VERSION_SUPPORTS_LINUXTHREADS_OLD
- BR2_UCLIBC_VERSION_SUPPORTS_NPTL
They are selected by the different uClibc versions, depending on which
thread implementation they support on the different architectures.
Then, the choice of the thread implementation can rely on those
booleans to know if a given thread implementation is available in the
current architecture / uClibc version selection.
This makes sure that unusable thread implementation do not get
selected, therefore fixing build issues such as:
http://autobuild.buildroot.org/results/89e/89e423bee040cbce3e82cd89f1191efaac490c0d/
The support table is as follows (only taking into account
architectures that allow the selection of
BR2_TOOLCHAIN_BUILDROOT_UCLIBC, other architectures are not
considered) :
----uclibc---- uclibc-xtensa- --uclibc-arc-- --uclibc-ng---
LT LT.old NPTL LT LT.old NPTL LT LT.old NPTL LT LT.old NPTL
arc(le|eb) y y n n n n (1)
arm(eb) y y y n y y (2)
bfin n y n y y n
i386 y y y n n y (3)
m68k y y y y y n
mips(64)(el) y y y n n y
powerpc y y y n n y
sh y y y n n y
sparc y y y n n y
xtensa n y n n n y
x86_64 y y y n n y
(1) : uclibc-ng only has NPTL support for ARC but it requires a more
recent compiler version that hasn't been officially released
by Synopsys.
(2) : the general idea of uclibc-ng is to only support NPTL on
architectures where it is available. However, in order to
support ARM noMMU platforms, LT.old support has been kept on
ARM.
(3) : except i386 itself, which doesn't have what's needed for NPTL
support. i386 is simply not supported by uclibc-ng basically.

This commit adds support for a new uClibc version: uClibc-ng
1.0.0. Since its build system is for now exactly the same as the one
of uClibc, we don't create a new package, but instead simply add it as

The only special trick needed is the creation of a symlink to the

Since a while, the semantic of BR2_PREFER_STATIC_LIB has been changed
from "prefer static libraries when possible" to "use only static
libraries". The former semantic didn't make much sense, since the user
had absolutely no control/idea of which package would use static
libraries, and which packages would not. Therefore, for quite some
time, we have been starting to enforce that BR2_PREFER_STATIC_LIB
should really build everything with static libraries.
As a consequence, this patch renames BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS, and adjust the Config.in option accordingly.
This also helps preparing the addition of other options to select
shared, shared+static or just static.
Note that we have verified that this commit can be reproduced by
simply doing a global rename of BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS plus adding BR2_PREFER_STATIC_LIB to Config.in.legacy.

uClibc can be built stripped (implemented as link-time option in uClibc).
This could be useful for those who build root fs manually.
In Buildroot there is a global strip stage wich strips most of shared libs
in "target" folder (wexcept kernel modules known to not work properly being
stripped and libpthread required to be non-stripped for correct debugging with
gdb of multi-threaded apps).
So there're few problems with current implementation:
1. uClibc is being stripped 2 times (first on its build stage, second on
global Buildroot strip stage)
2. uClibc libs in "staging" folder are also always stripped except if
"no strip" (BR2_STRIP_none) is explicitly is selected in Buildroot config.
That makes it possible to remote debug uClibc libs on target only if target
rootfs was not stripped (which might not be possible due to huge libs
like Qt)
This patch disables embedded strip in uClibc (still users may modify uClibc
config and explicitly set "DOSTRIP=yes" if really needed).
Interesting that DOSTRIP was not only selected in uClibc config but also was
force set with Buildroot on uClibc configuration step with UCLIBC_STRIP_CONFIG.

to do weird things in the uclibc build. We can greatly simplify

Currently, the internal toolchain backend does a three stage gcc
build, with the following sequence of builds:
- build gcc-initial
- configure libc, install headers and start files
- build gcc-intermediate
- build libc
- build gcc-final
However, it turns out that this is not necessary, and only a two stage
gcc build is needed. At some point, it was believed that a three stage
gcc build was needed for NPTL based toolchains with old gcc versions,
but even a gcc 4.4 build with a NPTL toolchain works fine.
So, this commit switches the internal toolchain backend to use a two
stage gcc build: just gcc-initial and gcc-final. It does so by:
* Removing the custom dependency of all C libraries build step to
host-gcc-intermediate. Now the C library packages simply have to
depend on host-gcc-initial as a normal dependency (which they
already do), and that's it.
* Build and install both gcc *and* libgcc in
host-gcc-initial. Previously, only gcc was built and installed in
host-gcc-initial. libgcc was only done in host-gcc-intermediate,
but now we need libgcc to build the C library.
* Pass appropriate environment variables to get SSP (Stack Smashing
Protection) to work properly:
- Tell the compiler that the libc will provide the SSP support, by
passing gcc_cv_libc_provides_ssp=yes. In Buildroot, we have
chosen to use the SSP support from the C library instead of the
SSP support from the compiler (this is not changed by this patch
series, it was already the case).
- Tell glibc to *not* build its own programs with SSP support. The
issue is that if glibc detects that the compiler supports
-fstack-protector, then glibc uses it to build a few things with
SSP. However, at this point, the support is not complete (we
only have host-gcc-initial, and the C library is not completely
built). So, we pass libc_cv_ssp=no to tell the C library to not
use SSP support itself. Note that this is not a big loss: only a
few parts of the C library were built with -fstack-protector,
not the entire library.
* A special change is needed for ARC, because its libgcc depends on
the C library, which breaks building libgcc in
host-gcc-initial. This looks like a bug in the ARC compiler, as it
does not obey the inhibit_libc variable which tells the compiler
build process to *not* enable things that depend on the C
library. So for now, in host-gcc-initial, we simply disable the
build of libgmon.a for ARC. It's going to be built as part of
host-gcc-final, so the final compiler will have gmon support.
