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.

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.

There used to be a mechanism using which packages could leave a

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

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

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.

The previous commit has removed calls to conf_write_autoconf(), which
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.

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.

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

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

Lay down the path to add more than two toolchain kinds:
- check the type of toolchain as:
ifeq (toolchain_buildroot,y)
blabla buildroot-specific
else ifeq (toolchain_external,y)
blabla external-specific
endif
- prefer using positive checks, a-la:
ifeq (foo,y)
instead of:
ifneq (bar,y)
(where foo and bar are mutually exclusive)
- have the toolchain_buildroot case always appear first
- gettext is handled differently, because we want to add an option
only if not using the buildroot toolchain, hence we use ifneq.

The "project" feature was designed to allow to several projects to be
built inside the same Buildroot source tree and allowing the toolchain
and non-configurable packages to be shared between the different
projects on the same architecture. While being interesting in theory,
this feature adds a level of complexity to Buildroot, both from an
user perspective and from a developer perspective, while one of the
main Buildroot strengh is to be simple. Moreover, this feature is only
seldomly used by our users.
From a user-level perspective, this for example allows to remove the
project_build_ARCH directory, which was very confusing. The
autotools-stamps directory is also removed, since these stamps are
back at their normal location.
Description of the changes involved :
* project/, directory removed
* Makefile
- Don't include project/Makefile.in and project/project.mk anymore
- Grab a copy of the contents of project/Makefile.in at the
location it was imported, but remove the definition related to
PROJECT_BUILD_DIR. The TARGET_DIR is now in
$(BUILD_DIR)/target_dir
- Remove the creation/removal of the $(PROJECT_BUILD_DIR) and
$(PROJECT_BUILD_DIR)/autotools-stamps directories
- Don't make world depends on target-host-info. This target was
defined by project/project.mk to customize /etc/issue,
/etc/hostname and create /etc/br-version depending on the
project definitions. We can of course imagine re-adding such a
feature later.
- Replace PROJECT_BUILD_DIR by BUILD_DIR everywhere
- Remove the update, log and lognr.$(PROJECT) target, they were
specific to the project feature.
* package/Makefile.autotools.in
- Replace PROJECT_BUILD_DIR by BUILD_DIR for the location of the
configure cache
- Move the INSTALL_TARGET and HOOK_POST_INSTALL stamps to the same
directory as the other stamps (i.e, in the package directory).
* package/Makefile.in
- Replace PROJECT_BUILD_DIR by BUILD_DIR for the location of the
configure cache
* package/at/at.mk,
package/busybox/busybox.mk,
package/busybox/initramfs.mk,
package/customize/customize.mk,
package/linux-fusion/linux-fusion.mk,

- Do not include project/Config.in anymore
* target/linux/Makefile.in.advanced
- Replace PROJECT_BUILD_DIR by BUILD_DIR
- Store the stamps file in $(STAMP_DIR) instead of
$(PROJECT_BUILD_DIR)/autotools-stamps

- Replace PROJECT_BUILD_DIR by BUILD_DIR
- Remove $(PROJECT) from the U-Boot target binary name
- Remove the insertion in the configuration of the project name as
the hostname

Remove toolchain build dir, and don't try to remove the non-existing include

we're already removing that dir.
Add BR2_ENABLE_LOCALE_PURGE / BR2_ENABLE_LOCALE_WHITELIST options to
remove unwanted locales from the target rootfs. Handy for stuff like
the gtk stack, which comes with ~25 MB locales.
Works similar to localepurge in Debian, E.G. you provide a white list
of wanted locales, and everything else is removed.
Move stamp (dependency) files outside the (version specific) source
directories, so other packages can hardcode dependencies on them instead
of having to use <PACKAGE>_VERSION variables.
This is important as the variables in the make rules are evaluated when
the rules is seen, which might be before the dependent makefile is parsed
(and hence <PACKAGE>_VERSION variable is known, screwing up stuff.
The downside of this is that the package isn't automatically rebuilt
when the version changes (E.G. by a svn update) and you now also have to
remove the stamp files next to $(BUILD_DIR)/<PACKAGE>-* to force a rebuild.
I often find myself forgetting what those targets were called, and I imagine
others may not even be aware of their existence.

HOST_GLIB is set to the path that contains the host glib tool set and is
used when building packages using glib. The buildroot top level Makefile
sets HOST_GLIB using which to find the path where glib-genmarshal is
located.
The problem is that a cross compiled version of glib-genmarshal is also
put in the build_ARCH/staging_dir/usr/bin directory when the package
libglib2 is built. This cross compiled version will typically not run on
the host system.
Fix it by ignoring staging_dir in the which output.

Improve external toolchain support
* Do not put kernel-headers in the dependencies of BASE_TARGETS in
the case where BR2_TOOLCHAIN_SOURCE is not y. The kernel headers
are already supposed to be part of the external toolchain, so
there's no need to download, extract and install them.
* In the configuration system, don't display the kernel headers
version selection list when an external toolchain is selected. This
is implemented by moving the source
"toolchain/kernel-headers/Config.in" inside the if
BR2_TOOLCHAIN_SOURCE in toolchain/Config.in.2.
* Change the description and help message of the BR2_LARGEFILE,
BR2_INET_IPV6, BR2_INET_RPC, and BR2_SOFT_FLOAT option in
toolchain/external-toolchain/Config.in. In the case of an external
toolchain, the semantic of these options is not to enable large
file support, IPV6 or RPC (since the toolchain is already compiled,
it has been decided previously). Their semantic is to let Buildroot
know about the characteristics of the external toolchain being
used.
As an improvement, we could guess these values automatically:
- for BR2_LARGEFILE, look at the value of __UCLIBC_HAS_LFS__ in
bits/uClibc_config.h in the libc headers directory.
- for BR2_INET_RPC, look at the value of __UCLIBC_HAS_RPC__ in the
same file
- for BR2_INET_IPV6, look at the value of __UCLIBC_HAS_IPV6__ in
the same file
- for BR2_SOFT_FLOAT, look at the output of $(CC) -v 2>&1 | grep
-- "--with-float=soft"
But I'm not sure how this would be possible, since these values are
used at configuration-time by other configuration options, not only
at build time.

=========================================================
The purpose of the BSP patch is to allow building
several boards inside the same buildroot tree.
For this to work, each board has to have its
own "$(TARGET_DIR)" and all *configurable* packages
must be rebuilt for each board.
They are now built in the "$(PROJECT_BUILD_DIR)"
All non configurable packages can and should still
be built in the "$(BUILD_DIR)".
If a package is built for one board, then when
you build for a second board of the same architecture
the build becomes a simple copy of the resulting
binaries.
-----
Define BR2_PROJECT which will be used as the selector
between different boards. Note that BR2_PROJECT allow
you to build multiple root file systems for a single
board, and should not be confused with BR2_BOARD_NAME
which relates to the H/W.
-----
Define PROJECT_BUILD_DIR as "PROJECT_BUILD_DIR/$(PROJECT)"
Define BINARIES_DIR as "binaries/$(PROJECT)"
Define TARGET_DIR as "$(PROJECT_BUILD_DIR)/root"
(some prefix/postfix may apply)
Resulting images are stored in "$(BINARIES_DIR)"
-----
Define a few new environment variables in Makefile
PROJECT: Stripped BR2_PROJECT
DATE: Date of build in YYYY-MM-DD format
HOSTNAME: Stripped BR2_HOSTNAME => /etc/hostname
BANNER: Stripped BR2_BANNER => /etc/issue
Linux and Busybox will be built in $(PROJECT_BUILD_DIR)
More patches will be needed later to ensure all
configurable packages are built in this directory.
This also provides a nice up-to-date filestamp if something got reconfigured (e.g. c++ support got toggled) that can be used in the future to depend accordingly.
This patch changes the way the top level Makefile searches for a
<board>_defconfig file, it will only look in the target/ directory and its sub
directories.
The patch also enables loading a defconfig even if there already is a .config.

libs, move openssl shared libs out of /lib, reduce size of libssl.so
by dynamicly linking with libcrypto.so, fix dropbear compile on mips.
Add support for libstd++ in full locale mode, and remove the need for
config hacks when using uClibc stub locale support.
TODO --
gdb intl support is still broken.
uClibc should auto-download the pregenerated locale data
configuration rather than before.
Try a different approach to avoid version-specific uClibc issues,
using '-nt' (newer than) test, and files
$(UCLIBC_DIR)/.installed{,runtime}
