* package: add configuration option to specify a local override fileThomas Petazzoni2011-09-291-0/+7
| | | | | | | | | | | | | | | | | The user can now create a custom local override file to override the source directory for various packages. 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.

* support: move package/gnuconfig to support/gnuconfigThomas Petazzoni2011-09-171-1/+1
| | | | | | | | | | | | The CONFIG_UPDATE macro is no longer defined in package/gnuconfig/gnuconfig.mk, but instead in package/Makefile.autotools.in. It it also changed a little bit to take the directory of the package sources as argument, and the AUTOTARGETS infrastructure is updated to use this macro.

* 'source' target should depend on 'dirs'Thomas De Schampheleire2011-08-041-1/+1
| | | | | | | | | | | | | | In the following command flow: make distclean make <board>_defconfig make source the dl directory would normally be created by the first wget download. If there are no such downloads, e.g. because you use a local download mirror (e.g. scp, file) or only use git/svn/hg/bzr repositories, the dl directory is not created automatically. This causes e.g. the 'pushd' command in the respective _DOWNLOAD commands to fail. This patch adds a dependency to the 'dirs' target to 'source', fixing this scenario.

* Makefile: unbreak source-checkYann E. MORIN2011-07-151-4/+1
| | | | | | | | | | | 'source-check' breaks because the *_DEFCONFIG options are empty strings. There is an explicit check to avoid erroring-out when doing 'source', but not when doing 'source-check'.

* Get rid of unneeded CFLAGSPeter Korsgaard2011-05-051-4/+4
| | | | | | | | Now that we use a wrapper for external toolchains (and internal ones default to the correct setting), we no longer need to explicitly pass sysroot/march/mtune/mabi/floating point mode in TARGET_CFLAGS. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
* Add toolchain wrapper for external toolchainsPeter Korsgaard2011-05-051-3/+1
| | | | | | | | | | | | | | | | Add a simple toolchain wrapper for external toolchains, which forces the correct sysroot/march/mtune/floating point options needed to use it with buildroot. With this in place the external toolchain behaves similar to the internal ones, and the special handling can be removed. This also means that the toolchain is usable outside buildroot without having to pass any special compiler flags. Also adjust the downloadable external toolchain support to install under HOST_DIR so it can be used after the temporary build files are removed. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

* Fix ccache handlingThomas Petazzoni2011-04-021-1/+1
| | | | | | | | | | | | | | | | | | When ccache support is enabled and 'make silentoldconfig' is being started from the following rule: $(BUILD_DIR)/buildroot-config/auto.conf: $(CONFIG_DIR)/.config $(MAKE) $(EXTRAMAKEARGS) HOSTCC="$(HOSTCC_NOCCACHE)" HOSTCXX="$(HOSTCXX_NOCCACHE)" silentoldconfig then, the Makefile in package/config inherits from HOSTCC/HOSTCXX values with the ccache prefix. However, if we start from a cleaned build (after make clean), ccache is not compiled yet, so things break. To solve this, we pass a noccache variant of HOSTCC/HOSTCXX down to the package/config Makefile.

* hostcc/hostcxx: fix noccache variant settingMike Frysinger2011-03-281-2/+2
| | | | | | | | | | | The current code accidentally sets up HOSTCC_NOCCACHE and HOSTCXX_NOCCACHE only when the respective HOSTCC or HOSTCXX values are not set. So if you do something like: make HOSTCC=gcc menuconfig The build fails because HOSTCC_NOCCACHE is not set anywhere.

* 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.

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