The BR2_ENABLE_DEBUG option selects the compilation and installation
of gdbserver on the target. This is a bit restrictive, especially for
external toolchains, which may already contain a gdbserver on the
target.

This allows ccache to re-use its cache contents even if the compiler
binary mtime has changed. It is the simplest approach to solve this
problem, and it works for the internal, external and crosstool-ng
toolchain backends.
Of course, it leaves the user responsible for invalidating the cache
when necessary, but there doesn't seem to be a real good solution that
allows both to: 1/ keep the cache contents accross builds and re-use
it and 2/ invalidate the cache automatically when the compiler chances
in an incompatible way.

Most of the host packages don't have to be exposed to the user as they
are only used as build dependencies of target packages.
However, some host utilities, such as flashing utilities, image
creation programs, specific debuggers, might be useful and should be
presented to the user.
Therefore, we have a new global menu, which lists those host
utilities. These utilities are described in package/*/Config.in.host
files, which will be sourced by package/Config.in.host.

This can be used this way :
<pkg>_VERSION = 42
<pkg>_SITE = file:///some/local/directory
<pkg>_SOURCE = mypkg-$(<pkg>_VERSION).tar.bz2
Can be useful to integrate a home-made project or for testing purposes.
The default command to retrieve files is 'cp' but 'rsync' could also be used.
Through sshfs, it should also be possible to get non-public remote files on a
ssh server.

The user can now create a custom local override file to override the
source directory for various packages.
An example override file:
ZLIB_OVERRIDE_SRCDIR = /tmp/zlib
STRACE_OVERRIDE_SRCDIR = /opt/strace-4.5.20
would tell Buildroot to use the zlib and strace source code from the

The stripping options operate on the final image and not the intermediate
builds, so requiring stripping to be disabled just to enable debugging
options doesn't make much sense. Especially when working with gdbserver:
only the host needs the debugging information to be available. The board
can run & debug perfectly fine without it.

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
infrastructure and usage.

This patch introduces a single, simple, infrastructure to build the
Linux kernel. The configuration is limited to :
* Kernel version: a fixed recent stable version, same as kernel
headers version (for internal toolchains only), custom stable
version, or custom tarball URL
* Kernel patch: either a local file, directory or an URL
* Kernel configuration: either the name of a defconfig or the
location of a custom configuration file
* Kernel image: either uImage, bzImage, zImage or vmlinux.

It speeds up configuration considerably.
If a package breaks due to wrong cache-entries, then the broken

In the output directory, we now have

- images/ where the final kernel and rootfs images are stored
- staging/ the staging directory (containing the development files
and libraries compiled for the target)
- target/ which contains the target root filesystem
- host/ which contains all the host programs
- stamps/ which contains the stamps files
Therefore, the build_ARCH and toolchain_build_ARCH have been

for different architectures are invited to use the O= command line

all the different COPYTOs spread out all over
Buildroot.
Generate COPY_FILE subroutine which can be used
to copy a file.
$(COPY_FILE , file, directory, filename)
This will copy to binary dir and to the selected
copy dir if set in new config (intended to replace
all old COPYTO configs)
This is overridden by BUILDROOT_COPYTO,
if set into the environment.
The following changes allow for use of a central configure cache
file. This speeds up configuration of packages.
Its use is configurable at the top level (BR2_CONFIG_CACHE - default n).
Old style makefiles can use it if they use the following MACRO in makefiles:
$(AUTO_CONFIGURE_TARGET) see my change to directfb.mk.
New style Autotools.in will use it if you set the global option.
However you can enable the global option and on a per package overrule it by doing
the following: $(PKGNAME)_USE_CONFIG_CACHE = NO see fontconfig.mk for an example
of this.
Finally I have removed a few config variable settings which indicated no CXX compiler
as this is wrong and breaks the build when using this central cache.
Config.in | 8 ++++++++
package/Makefile.autotools.in | 5 ++++-
package/Makefile.in | 28 +++++++++++++++++++++++++++-

I would appreciate feedback on this change (I have been testing for 2-3 weeks)
But I can never test all cases! If you enable the BR2_CONFIG_CACHE option some
Makefile.autotools.in based packages may now break - I cannot build them all.
In this case you may need to remove config options that are being hardcoded all
over the place (like gtk saying we have 2 CXX compiler) or disable the use
of CONFIG CACHE file like I have done in fontconfig.
I can build all packages required to get WebKit on DirectFB up and running
and it runs fine.
I will try to resolve any issues this creates as fast as I can.
