07bae75635 source-check: change behavior to check only selected packages / add source-check-all
The original 'source-check' target first selects all packages, and then checks
whether the package tarballs can be found. This is useful for Buildroot
maintainers, but less useful for developers working on a specific project. The
latter only care about the packages used in that project.

This patch removes the allyesconfig dependency to source-check so that only
selected packages are checked. The original behavior is moved to a new target
'source-check-all'.

[Peter: removed source-check-all, people can just make allyesconfig before]

2a97045d5d build: add option to exclude executables/dirs from being stripped
Sometimes it may be desirable to keep debug symbols for some binaries and
libraries on the target. This commit introduces the config option
BR2_STRIP_EXCLUDE_FILES, which is interpreted as a list of such binaries
and libraries, and the option BR2_STRIP_EXCLUDE_DIRS, which indicates
directories excluded from stripping entirely.
These exclusions are passed to the find command in the target-finalize step.

433290761f ccache: allow dynamic selection of cache directory
The existing ccache infrastructure sets the cache directory hardcoded in the
ccache binary. As this directory was set to ~/.buildroot-ccache, the cache
is not necessarily local (e.g. in corporate environments the home directories
may be mounted over NFS.)
Previous versions of buildroot did allow to set the cache directory, but this
was also hardcoded (so you had to rebuild ccache to change it), plus that
support was removed.
See http://lists.busybox.net/pipermail/buildroot/2011-July/044511.html for
a discussion on this.

This patch modifies ccache to respect a new shell variable (exported from
the Makefile, based on a configuration option) instead of CCACHE_DIR.
The name CCACHE_DIR itself is already used by autotargets for the ccache
package.

aebf199ff0 Add support to generate locale data
In order to use locale support on a Linux system, you need locale data
to be present:

 * on a (e)glibc based system, this data is typically in the
   /usr/lib/locale/locale-archive file, which can be created and
   extended using the localedef program

 * on an uClibc based system, the set of supported locales is defined
   at build time by an uClibc configuration option.

This patch implements generating locale data for the following cases:

 * Internal toolchain

 * External toolchain based on (e)glibc. uClibc external toolchains
   are not supported, because with uClibc, the set of supported
   locales is defined at build time. CodeSourcery and Linaro
   toolchains have been tested, Crosstool-NG toolchains are believed
   to work properly as well.

 * Toolchains built using the Crosstool-NG backend, but only (e)glibc
   toolchains.

This feature was runtime tested with internal uClibc toolchain,
CodeSourcery ARM toolchain and Linaro ARM toolchain, thanks to a
simple C program that shows the data and a gettext translated message.

Note that this option differs from the "purge locales" option, which
is responsible for removing translation files and other locale stuff
installed by packages. At some point in the future, we may want to
clarify the respective roles of those options.

33f454bbef config: make it possible to specify which config file to use for 'make defconfig'
So that this works:

 % make defconfig BR2_DEFCONFIG=~/buildroot-defconfig

Right now we have to do:

 % cp ~/buildroot-defconfig configs/buildroot_defconfig
 % make buildroot_defconfig

That would dirty the buildroot tree and requires it to be writable.

4ef7ec585c Remove unused .fakeroot.* mechanism
There used to be a mechanism using which packages could leave a
.fakeroot.<something> file which could contain commands to be executed
within the fakeroot environment. Since this mechanism is no longer
used by any package, remove it from the common infrastructure.

The latest user was nfs-utils, which used this mechanism to do the
"make install" as root, since doing otherwise was not supported. But
since 16e7b8255c, nfs-utils has been
upgraded and converted to the package infrastructure, and this hack is
no longer necessary. Another past user was the ltp-testsuite package,
for the same reason, and since
a72a670489, the fakeroot hack is no
longer needed.

0edfb24c38 dependencies: check minimal make version early on
Although support/dependencies/dependencies.sh checks for the version of make,
this script doesn't get a chance to run if make encounters a syntax error as a
result of being too old.

For example, the following syntax is only supported from make 3.81 onwards:

ifeq ($(BR2_TOOLCHAIN_BUILDROOT),y)
include toolchain/toolchain-buildroot.mk
else ifeq ($(BR2_TOOLCHAIN_EXTERNAL),y)
include toolchain/toolchain-external.mk
else ifeq ($(BR2_TOOLCHAIN_CTNG),y)
include toolchain/toolchain-crosstool-ng.mk
endif

This patch adds a check for the version of make very early in the Makefile, so
that old make versions are handled gracefully.

4eb982cf90 'source' target should depend on 'dirs'
In the following command flow:
make distclean
make <board>_defconfig
make source

the dl directory would normally be created by the first wget download. If there are no such downloads, e.g. because you use a local download mirror (e.g. scp, file) or only use git/svn/hg/bzr repositories, the dl directory is not created automatically. This causes e.g. the 'pushd' command in the respective _DOWNLOAD commands to fail.

This patch adds a dependency to the 'dirs' target to 'source', fixing this scenario.

125e2558b2 Get rid of unneeded CFLAGS
Now that we use a wrapper for external toolchains (and internal ones

85dc57f6fd Add toolchain wrapper for external toolchains
Add a simple toolchain wrapper for external toolchains, which forces the
correct sysroot/march/mtune/floating point options needed to use it
with buildroot.

With this in place the external toolchain behaves similar to the internal
ones, and the special handling can be removed. This also means that the
toolchain is usable outside buildroot without having to pass any special
compiler flags.

Also adjust the downloadable external toolchain support to install under
HOST_DIR so it can be used after the temporary build files are removed.

c729829c6c Fix ccache handling
When ccache support is enabled and 'make silentoldconfig' is being
started from the following rule:

$(BUILD_DIR)/buildroot-config/auto.conf: $(CONFIG_DIR)/.config
	$(MAKE) $(EXTRAMAKEARGS) HOSTCC="$(HOSTCC_NOCCACHE)" HOSTCXX="$(HOSTCXX_NOCCACHE)" silentoldconfig

then, the Makefile in package/config inherits from HOSTCC/HOSTCXX
values with the ccache prefix. However, if we start from a cleaned
build (after make clean), ccache is not compiled yet, so things break.

To solve this, we pass a noccache variant of HOSTCC/HOSTCXX down to
the package/config Makefile.

toolchain, we define a set of profiles for well-known external
toolchains (CodeSourcery ones only at the moment, can easily be

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
profile is available.

22c2c6b541 Makefile: handle host packages for make source / make external-deps
Ensure host packages (dependencies of target packages) are also handled
by make source / make external-deps.

This has to be done a explicitly, as we don't list these in Kconfig,
and hence also not in a variable like TARGETS, so instead we have to
look at the <PKG>_DEPENDENCIES variables for each enabled package and
extract the host packages from there.

Host packages can in turn also have dependencies, so we have to follow
those as well. Ideally this should be done recursively, but as that's
pretty hard to do in make, it is limited to 1 level for now.

Finally, host packages share source files with target packages, so
pipe output of make external-deps through sort -u to ensure duplicates
are removed.

5f71fc1f19 Remove support for shared configuration cache
The configuration cache shared between packages, while being in
principle a nice idea to speed-up the configuration of packages by
avoiding repetitive identical checks, turned out to be unreliable due
to the subtle differences between similar but not identical checks in
different packages. After spending some time trying to fix those, we
concluded that supporting the shared configuration cache is definitely
too hard and too unreliable, and that we'd better get rid of it
altogether.

This patch therefore removes the shared configuration cache

aefad5317f Makefile: generate a Makefile wrapper in $(O)
If building out-of-tree, add a Makefile wrapper that calls-out to the real
Makefile with proper args.

Avoids having to pass -C and O= every time we call make.

This is highly inspired from how the Linux kernel does it, and portions of
it have been used. We can't use exactly the same implementation as the
kernel does, because:

 - the script writing the wrapper has been expunged of the few lines
   that were too kernel-related: in buildroot we do not need the version
   string in the wrapper, and we do not have a patchlevel version;

 - "in-tree build" does not have the same meaning for the kernel and for
   buildroot: for the kernel, $(O) point to the $(TOPDIR), while for
   buildroot $(O) points to $(TOPDIR)/output.

is the function that generates the KCONFIG_AUTOCONF,
KCONFIG_AUTOHEADER, KCONFIG_TRISTATE files and the split config (with
one file per config item). Therefore, those things were not generated
anymore before the build.

In order to get them generated before the build, we use the same
mechanism as the kernel: run a silentoldconfig when the .config file
is newer than the KCONFIG_AUTOCONF file.

In Buildroot, all those elements are not really used today, except the
split config which is used a little bit in the toolchain build, in a
try to make sure the toolchain gets rebuilt properly when the
configuration changes. It does not seem that this work has been
completed.

However, as we want to keep the same behaviour as previously, we have
to generate all those elements before starting the build.

e1b1a18ab6 Add support for savedefconfig
savedefconfig allows to create a minimal defconfig file from an
existing configuration. For example :

 make O=/path/to/some/buildroot/build/directory savedefconfig

will generate a minimal 'defconfig' file in the main Buildroot source
directory.

7c524dd0b6 Clean up our patches against kconfig
Our kconfig-to-buildroot2.patch hasn't been kept up to date with all
the changes made into package/config, and a single patch wasn't very
practical to maintain all our changes. Therefore, this commit adds a
package/config/patches directory, which contains a Quilt series of
patches that correspond to our modifications to the kconfig mechanism.

The huge kconfig-to-buildroot2.patch has been split into 16 smaller
patches. The purpose of some of the modifications has been clearly
identified, while some others were not identified.

The 16 patches together do match exactly the old
kconfig-to-buildroot2.patch. We have been very careful in making sure
that we wouldn't loose any of our modifications.

The only modifications made are :

 * Instead of renaming the kernel Makefile to Makefile.kconfig and
   naming the Buildroot Makefile just 'Makefile', we instead keep the
   original package/config/Makefile from the kernel
   scripts/kconfig/Makefile and name the Buildroot Makefile
   package/config/Makefile.br. The main Buildroot Makefile is modified
   accordingly.

 * The documentation README.buildroot2 is updated to explain how to
   upgrade to a newer version of scripts/kconfig.

 * The kconfig-language.txt documentation is removed, as anybody can
   easily find it in the kernel sources so there's no need to
   duplicate it here.

4ccde7fabb Fix ldconfig call in target-finalize
Recent versions of ldconfig require the directory /var/lib/ldconfig,
otherwise they bail out with an error. Moreover, having a
/etc/ld.so.conf file also avoids a warning.

In addition to this, we remove the redirection of stderr, so that
errors remain visible to the user.

Thanks to Baruch Siach, Andy Gibbs and Darcy Watkins for investigating
the issue and proposing solutions.

This fixes the build on recent distributions such as Fedora 13 or
Gentoo.

de846f6e04 Makefile: fix source/source-check/external-deps with O=
Based on patch by Will Wagner <will_wagner@carallon.com>.

Now that the .config is located in the output directory when O=<dir>
is used, we have to pass the O= option to make for
source/source-check/external-deps to get them to look in the right place
for the .config.

Fix it by introducing an EXTRAMAKEARGS variable and use it whenever we
call back into the toplevel Makefile.

ed0200993e toolchain: move makefile includes
Including a bunch of Makefiles with wildcard makes it impossible to add
new toolchain backends. Avoid that by namely including needed files.

The external toolchain still needs to include all the toolchain/*/*.mk
sub-makefiles, as they are needed to build a toolchain that runs on the
target. It is to be noted that the cross-toolchain is not built in this
case, as the make-targets to build the cross-toolchain are not present
in the $(BASE_TARGETS) variable, which is later used to create the
dependency rules.

Also, the comment 'Explicit ordering' has been removed, as it is mis-
leading. It is make's responsibility to create the proper ordering based
on the dependency rules it finds in the Makefiles

e49e2feda4 Makefile: fix ldconfig selection for internal toolchains
Commit ed0d45fdd (Choose host/target ldconfig based on availability)
added a runtime check for a cross-ldconfig being available.
Unfortunately this checks runs too early (at package/Makefile.in parsing
time), so it always fails when using an internal toolchain as ldconfig
isn't built yet.

Fix it by moving the check to the only place it is used (target-finalize).

 * Kernel patch: either a local file, directory or an URL

 * Kernel configuration: either the name of a defconfig or the

Likewise, when changing between using O= or not (or simply running
