* Deprecate the support for the toolchain on targetThomas Petazzoni2012-11-171-0/+4
| | | | | | | | | | | | | | | | As discussed during the ELCE 2012 Buildroot Developers Meeting, we no longer want to support the possibility of building a toolchain for the target. None of the core developers have any use for this, it has been known to be broken or cause problems for a long time without anyone providing fixes for it. In addition to this, Buildroot is inherently a cross-compilation tool, so the usage of a native toolchain on the target is not really useful. Many newcomers are tempted to use this possibility even though it is clearly not the intended usage of Buildroot.

* Split target/Config.in.arch into multiple Config.in.* in arch/Thomas Petazzoni2012-11-041-1/+1
| | | | | | | | | | | | | | | | | | | target/Config.in.arch had become too long, and we want to remove the target/ directory. So let's move it to arch/ and split it this way: * An initial Config.in that lists the top-level architecture, and sources the arch-specific Config.in.<arch> files, as well as Config.in.common (see below) * One Config.in.<arch> per architecture, listing the CPU families, ABI choices, etc. * One Config.in.common that defines the gcc mtune, march, mcpu values and other hidden options.

* New top-level directory: systemThomas Petazzoni2012-11-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | This directory groups the following elements: * the default root filesystem skeleton * the default device tables * the Config.in options for system configuration (UART port for getty, system hostname, etc.) * the make rules to apply the system configuration options Even though the skeleton and device tables could have lived in fs/, it would have been strange to have the UART, system hostname and other related options into fs/. A new system/ directory makes more sense. As a consequence, this patch also removes target/Makefile.in, which has become useless in the process.

* Package downloads: allow restricting to primary site onlyThomas De Schampheleire2012-07-221-0/+18
| | | | | | | | | | | | | | | | | | | This patch adds a new config option BR2_PRIMARY_SITE_ONLY that, when set, restricts package downloads to the specified BR2_PRIMARY_SITE. If the package is not present on the primary site, the download fails. This is useful for project developers who want to ensure that the project can be built even if the upstream tarball locations disappear.

* build: add option to exclude executables/dirs from being strippedThomas De Schampheleire2012-06-231-0/+19
| | | | | | | | | | | | | | 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.

* ccache: allow dynamic selection of cache directoryThomas De Schampheleire2012-05-181-0/+7
| | | | | | | | | | | | | | | | | | | | 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.

* debug: do not force installation of gdbserverThomas Petazzoni2012-03-151-1/+0
| | | | | | | | | | The BR2_ENABLE_DEBUG option selects the compilation and installation of gdbserver on the target.

* ccache: set COMPILERCHECK to 'none'Thomas Petazzoni2012-03-081-0/+7
| | | | | | | | | | | | | | | | 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.

* Add basic config infrastructure for host utilitiesThomas Petazzoni2012-02-021-0/+2
| | | | | | | | | | | | | | | | | | 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.

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 specified directories, instead of download, extracting and patching the code has done usually by Buildroot.

* Remove support for shared configuration cacheThomas Petazzoni2010-11-051-14/+0
| | | | | | | | | | | | | | | | | 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.
