* Makefile: rename cross target -> toolchainFabio Porcedda2013-01-151-4/+5
| | | | | | | | | | | | | | | - Use a more descriptive name, the same of the "toolchain" directory. - Add missing dependencies to be able to successfully use the target right after the configuration. - Move to a better position. - Documentation it in the help target. - Use toolchain target in the world target Signed-off-by: Fabio Porcedda <fabio.porcedda@gmail.com> Reviewed-by: Markos Chandras <markos.chandras at imgtec.com> Acked-by: Arnout Vandecappelle (Essensium/Mind) <arnout at mind.be> Acked-by: Samuel Martin <s.martin49 at gmail.com> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
* Integration with Buildroot Toolchain Eclipse pluginThomas Petazzoni2013-01-141-0/+7
| | | | | | | | | | | | | | | | | | The Eclipse plugin at https://github.com/mbats/eclipse-buildroot-toolchain-plugin allows users of Eclipse to easily use the toolchain available in Buildroot. To do so, this plugin reads ~/.buildroot-eclipse.toolchains, which contains the list of Buildroot toolchains available on the system, and then offer those toolchains to compile Eclipse projects. In order to interface with this plugin, this commit adds an option that allows the user to tell whether (s)he wants the Buildroot project toolchain to be visible under this Eclipse plugin. It simply adds a line in this ~/.buildroot-eclipse.toolchains file. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
* Makefile: don't export O to the environmentPeter Korsgaard2013-01-141-1/+1
| | | | | | | | Several projects use the kernel style O=<dir> syntax to build out of tree, and atleast uClibc doesn't check that it was explictly passed on the command line, so setting it in the environment breaks the build. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

* Makefile: export a few variables to help support scriptsYann E. MORIN2013-01-131-0/+11
| | | | | | | | | | | | | | | | | | | | | | | Support scripts (in support/) may need to parse the .config file, so give them an easy access to it, by exporting BUILDROOT_CONFIG with the fully- qualified path to .config. Also, post-build scripts may need to reference a few locations, so export those, too. Note: we export both O and BASE_DIR. Although they are the same, BASE_DIR is used internally, while O is used on the command line, which makes it a bit ambiguous to know which to use. As users use O= on the command line, they will probably tend to use that in their post-build scripts. Update doc accordingly. [Peter: fixed typo] Signed-off-by: "Yann E.

* pkg-infra: introduce errors for legacy APIArnout Vandecappelle (Essensium/Mind)2012-11-301-1/+6
| | | | | | | | | | | | | As discussed in the BR developer days, we want to be more strict about API changes in buildroot. I.e., we want to make it less likely that a user's customizations break down after upgrading buildroot. A first step is to make sure that the user is warned about API changes. This patch introduces Makefile.legacy and Config.in.legacy, which will issue clear error messages for such situations.

* Warn the user about the usage of output/target as the root filesystemThomas Petazzoni2012-11-171-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A very common mistake done by our users is that they use output/target/ directory as their root filesystem. Even though this is loudly documented in our Buildroot manual, people don't read documentation, so it is not sufficient. This patch adds a text file named output/target/THIS_IS_NOT_YOUR_ROOT_FILESYSTEM which explains why output/target isn't appropriate to use as the root filesystem. The process is: * At the beginning of the build, right after the skeleton has been copied, support/misc/target-dir-warning.txt is copied to output/target/THIS_IS_NOT_YOUR_ROOT_FILESYSTEM * In the filesystem images creation code, this file is removed before launching fakeroot, and restored right after that, so that this file is not present in the generated root filesystem images. Note that the file has not been added to the default skeleton for two reasons: * It would have annoying to have in our source tree a file named in capital letters inside system/skeleton/ * The proposed way works even if the user uses a custom skeleton.

* New top-level directory: systemThomas Petazzoni2012-11-041-2/+2

A new system/ directory makes more sense. As a consequence, this patch also removes target/Makefile.in, which has become useless in the process.

| | | | | | | | | | | | | | As stated in commit 555c2585bf28c3ef71f6d2dcdd983d17a19892af, the Xtensa architecture has been introduced in 2009 and never changed since its initial introduction. It requires some special handling that is a bit annoying, and despite our call to the initial developers, and the announcement of the deprecation of the architecture during the 2012.05, nothing has happened.

* legal-info: infrastructure to collect legally-relevant materialLuca Ceresoli2012-07-171-3/+39
| | | | | | | | | | | | | | | | | | | | | This allows to automatically collect material that may be needed to comply with the license of packages that Buildroot prepares for the target device. The core of the implementation is made by the following parts: - in package/pkg-utils.mk some helper functions are defined for common actions such as generating a warning, producing info about a package etc; - in package/pkg-gentargets.mk, within the GENTARGETS framework, a new <PKG>-legal-info target produces all the info for a given package; - Makefile implements the top-level targets: - legal-info-prepare creates the output directory and produces legal info about Buildroot itself and the toolchain, which mostly means just warning the user that this is not implemented; - legal-info, the only target that is supposed to be used directly, depends on all of the above and finishes things by producing the README files from the various pieces.

| | | | | | | | | | | | | | | | | | | | 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.

* ccache: allow dynamic selection of cache directoryThomas De Schampheleire2012-05-181-1/+2
| | | | | | | | | | | | | | | | | | | | 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.
