* Optimize (-O2) host binaries by defaultPeter Korsgaard2010-10-291-9/+0
| | | | | | | | | Default HOST_CFLAGS to -O2, so host tools (like the cross compiler) are built with optimization by default. Based on a patch by Will Newton <will.newton@gmail.com>. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

* Makefile: Force make to run serially in the top-level MakefileYann E. MORIN2010-09-301-0/+3
| | | | | | | | | | | | The top-level Makefile can be executed in parallel, as it causes problems. We can force make to be not parallel. It's been reported many times, and recent discussions on IRC with kos_tom, and user nick-named knee, led to this patch. Signed-off-by: "Yann E.

* Makefile: generate a Makefile wrapper in $(O)Yann E. MORIN2010-09-261-17/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Re-implement the source-check and external-deps targetsMaxime Petazzoni2010-09-131-11/+2
| | | | | | | | | | | | | | | The new DL_MODE variable dispatches between the various download implementations of each method (Git, Subversion, Wget) to deal with the normal download (default mode, 'DOWNLOAD'), the source-check ('SOURCE_CHECK') and to show the external dependencies for external-deps ('SHOW_EXTERNAL_DEPS'). For the latter, the legacy script wget-show-external-deps.sh is no longer required as $(WGET) isn't called directly anymore but always through the DOWNLOAD helper.

| * Ensure that all config-related files are generated before the buildThomas Petazzoni2010-09-011-7/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * Add support for savedefconfigThomas Petazzoni2010-09-011-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | 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.

| * Factorize environment variables for config utilitiesThomas Petazzoni2010-09-011-43/+23
| | | | | | | | | | | | | | | | | | | | | | Instead of duplicating the definition of KCONFIG_AUTOCONFIG, KCONFIG_AUTOHEADER and BUILDROOT_CONFIG, let's define them in a COMMON_CONFIG_ENV variable, which is used by all the xconfig, gconfig, menuconfig, nconfig, config, oldconfig, randconfig, allyesconfig, allnoconfig, randpackageconfig, allyespackageconfig, allnopackageconfig, defconfig, %_defconfig targets.

| * Clean up our patches against kconfigThomas Petazzoni2010-09-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | Fix ldconfig call in target-finalizeThomas Petazzoni2010-08-301-3/+7
|/ | | | | | | | | | | | | | | | | 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.

* Makefile: fix source/source-check/external-deps with O=Peter Korsgaard2010-08-291-8/+6
| | | | | | | | | | | | | | 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. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

* toolchain: move makefile includesYann E. MORIN2010-07-281-14/+2
| | | | | | | | | | | | | | | | | | | 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 Signed-off-by: Yann E.

* Makefile: fix ldconfig selection for internal toolchainsPeter Korsgaard2010-07-261-2/+6
| | | | | | | | | | | | 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). Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

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