2010-07-07Introduce support for host config cacheThomas Petazzoni
We now have for quite some time a configuration cache used to speed-up the execution of ./configure scripts when compiling programs for the target. This commit introduces a similar concept when Buildroot compiles programs for the host. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
2010-07-01Makefile: fixup make distclean after kconfig build in BUILD_DIRPeter Korsgaard
We don't actually need to explicitly clean the kconfig stuff, as distclean already removes the entire BUILD_DIR, but fix up the packag/config makefile to do the right thing if make clean/distclean is called manually for completeness. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

2010-06-22New, simpler, infrastructure for building the Linux kernelThomas Petazzoni
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.

2010-06-21kconfig: build in BUILD_DIR/buildroot-configPeter Korsgaard
This way the main buildroot dir can be completely read-only for out-of-tree builds Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
2010-06-21Makefile: fix make <blah>_defconfigPeter Korsgaard
Make sure we only pass O=<path> if we were originally called like that, otherwise we might end up looking for the .config in the wrong place. Likewise, when changing between using O= or not (or simply running make <blah>_defconfig in a pristine source tree), we do end up having a .config, but no .config.cmd. It isn't really critical so just continue even if we couldn't read it. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

2010-06-05Makefile: support gconfig (GTK-based configurator) similar to xconfigPeter Korsgaard
Support the GTK variant of the graphical kconfig configurator as an alternative to the Qt3-based one. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
2010-06-05Makefile: cleanup *conf targetsPeter Korsgaard
The make targets for the kconfig conf/mconf/qconf are almost identical, so us a single rule for it. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

2010-05-21Makefile: move filesystem stuff after u-boot build againPeter Korsgaard
Otherwise u-boot tools / kernel modules are only added to target AFTER the filesystems are built. Long term u-boot/kernel stuff should get splitted from target/device, but this is the safest solution for now. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

2010-05-06Makefile: make GNU_HOST_NAME a simply expanded variable (:=)Peter Korsgaard
GNU_HOST_NAME is referred more than 100 times in the tree, used 5 times during startup, and is relatively expensive to run - so make it a simple expanded variable (:=) rather than recursively expanded one (=). Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
2010-05-05Remove gtk-doc documentations from targetPaulius Zaleckas
On my target rootfs it is installed documentation for: atk, cairo, gdk, gdk-pixbuf, gio, glib, gobject, gtk, pango It ocupies 34M of space. Configure option --disable-gtk-doc doesn't prevent installation of it. So we should remove them manually if documentation is disabled.

2010-05-03Remove BR2_GNU_TARGET_SUFFIX and compute GNU_TARGET_NAMEThomas Petazzoni
Instead of asking the user about the GNU target suffix, just compute it automatically from the other configuration options. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
2010-05-03Commonalize the definition of TOOLCHAIN_DIRThomas Petazzoni
The definition of TOOLCHAIN_DIR is the same regardless of whether external or internal toolchains are used. Moreover, move its definition together with all the other *_DIR definitions.

2010-04-11Guess build system and remove BR2_GNU_BUILD_SUFFIXThomas Petazzoni
Instead of having a configuration option BR2_GNU_BUILD_SUFFIX, let's use config.guess to guess the build system type. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
2010-04-11Remove all documentation when BR2_HAVE_DOCUMENTATION is not setThomas Petazzoni
Until now, we had BR2_HAVE_MANPAGES, BR2_HAVE_INFOPAGES and BR2_HAVE_DOCUMENTATION, but there's no need to have such a fine-grained control over what documentation gets kept or not. Therefore, just remove all the documentation (man pages, info pages and documentation in $(TARGET_DIR)/usr/doc and $(TARGET_DIR)/usr/share/doc) when BR2_HAVE_DOCUMENTATION is not set.

2010-04-05Makefile: out-of-tree fix for uclibc 0.9.31Peter Korsgaard
Strangely enough O is still passed to submakes with MAKEOVERRIDES (with make 3.81 atleast), the only thing that changes is the output of the origin function (command line -> environment). Unfortunately some packages don't look at origin (E.G. uClibc 0.9.31+) To really make O go away, we have to override it. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
2010-03-31toolchain: prepare for more than two alternativesYann E. MORIN
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.

2009-12-13Makefile: fix build if CDPATH is set in environmentPeter Korsgaard
Reported by Bjørn Forsman <bjorn.forsman@gmail.com>. If CDPATH is set in the environment, cd <dir> will print the absolute path of <dir>, causing various trouble (The most critical being BASE_DIR ending up as <path> <path> which breaks basically everything). Fix it by clearing CDPATH. Notice that export doesn't affect the environment of $(shell ..) calls, so explicitly throw away any output from cd in the BASE_DIR shell call.

2009-12-12Makefile: drop config cache on .config changesPeter Korsgaard
The config cache might contain invalid values when .config is changed (E.G. when adding/removing libraries), so drop it so config checks are rerun for new packages (existing package still won't be rebuilt). Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
2009-11-30Makefile: use absolute path for TOPDIRPeter Korsgaard
Reported by mr_claus on IRC. This ensure DL_DIR is always an absolute path, like it was before the build dir reorganization - Fixes vim (patch) build. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
2009-11-20Makefile: cleanup *clean targetsPeter Korsgaard
As discussed on the list, fixup the *clean targets, so we now have: clean: remove all generated files (E.G. everything in output/) distclean: same as clean, but also remove the kconfig build and .config Also tweak 'make help' output to match. This also merges the two different clean / distclean targets we had depending on if there was a .config present or not (most variables are not defined for !.config case, so E.G. the clean target ends up being a noop). Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
2009-10-04buildroot; move defconfigs to configs/ and print in helpPeter Korsgaard
As discussed earlier on the mailing list. It simplifies code, gives more sensible error message on typos and makes the defconfigs easier to find for users. Furthermore, update documentation to match. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
2009-10-04Makefile: add rand/allyes/allno package config targetsPeter Korsgaard
Similar to the normal targets, but only affects the BR2_PACKAGE_* options. E.G. handy for keeping your current toolchain config while testing (random) packages. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
2009-10-04Makefile: update help textPeter Korsgaard
get rid of the removed saveconfig/getconfig targets, and instead document randconfig/defconfig/allyesconfig/allnoconfig. Furthermore, get rid of the unused tags target. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

2009-09-16Rename the output directoriesThomas Petazzoni
In the output directory, we now have - build/ where all the packages are built - 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 removed. People willing to use the same Buildroot sources to compile for different architectures are invited to use the O= command line option for out-of-tree compilation.

Instead of putting all the build-related stuff as a mess in the Buildroot sources, group them in an output/ directory. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
2009-09-16Remove the BOARD/LOCAL featureThomas Petazzoni
This can be achieved by adding a new target in target/device/, and I will later propose a mechanism to add external boards and packages, so that our users not willing to get their target-specific or package-specific things merged can keep them cleanly separated from Buildroot tree.
