* toolchain: add support for external toolchain profiles and downloadThomas Petazzoni2010-12-131-1/+2
| | | | | | | | | | | | | | | | | | | Instead of letting the user define all the details of his external toolchain, we define a set of profiles for well-known external toolchains (CodeSourcery ones only at the moment, can easily be extended with other toolchains). Once a profile has been choosen, the user is offered the choice of either letting Buildroot download and install the external toolchain, or (as before) to tell Buildroot where the toolchain is installed on the system. We of course provide a "custom profile", through which the user can configure Buildroot to use a custom external toolchain for which no profile is available.

* ccache: rework ccache managementThomas Petazzoni2010-12-081-6/+20
| | | | | | | | | | | | | | * ccache is now a normal package (both for the host and the target). * ccache option is now part of the "Build options" menu. It will automatically build ccache for the host before building anything, and will use it to cache builds for both host compilations and target compilations. * bump ccache to 3.1.3 Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

* Makefile: introduce KSTRIPCMD to strip kernel modulesGustavo Zacarias2010-11-301-1/+1
| | | | | | | | | | | | | | | When sstrip is selected it tries to strip kernel modules too. Unfortunately this fails with a "unrecognized program segment header size" error thus interrupting the build process. We introduce a new $(KSTRIPCMD) strip command for this, being a regular strip when sstrip is selected and an empty stub when not stripping. At the same time get rid of the REMOVE_SECTION_* variables, as they are only used once. Signed-off-by: Gustavo Zacarias <gustavo@zacarias.com.ar> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

* Makefile: handle host packages for make source / make external-depsPeter Korsgaard2010-11-191-1/+20
| | | | | | | | | | | | | | | | | | | | Ensure host packages (dependencies of target packages) are also handled by make source / make external-deps. This has to be done a explicitly, as we don't list these in Kconfig, and hence also not in a variable like TARGETS, so instead we have to look at the <PKG>_DEPENDENCIES variables for each enabled package and extract the host packages from there. Host packages can in turn also have dependencies, so we have to follow those as well. Ideally this should be done recursively, but as that's pretty hard to do in make, it is limited to 1 level for now. Finally, host packages share source files with target packages, so pipe output of make external-deps through sort -u to ensure duplicates are removed.

* Remove support for shared configuration cacheThomas Petazzoni2010-11-051-9/+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.

* 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.

| * 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.

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.

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