2011-04-25Makefile: make help: show busybox/ctng/linux/uclibc-menuconfig if enabledPeter Korsgaard
For this we need to read .config. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
2011-04-25Makefile: remove outdated make targetsPeter Korsgaard
busybox and linux26 no longer have a -config target, and prepatch only makes sense for a very specific configuration (BR toolchain with GDB enabled). Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

Closes #3541 Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
2011-04-02Fix ccache handlingThomas Petazzoni
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.

2011-03-28hostcc/hostcxx: fix noccache variant settingMike Frysinger
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.

2011-02-02toolchain: introduce HOST_DIR optionGustavo Zacarias
Allow the user to define HOST_DIR in the config menu. This way when building an internal toolchain a separate (maybe shared) output directory may be defined and the toolchain can be used by multiple users and/or projects.

2010-12-13toolchain: add support for external toolchain profiles and downloadThomas Petazzoni
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.

2010-12-08ccache: rework ccache managementThomas Petazzoni
* ccache is now a normal package (both for the host and the target). * ccache option is now part of the "Build options" menu.

2010-11-30Makefile: introduce KSTRIPCMD to strip kernel modulesGustavo Zacarias
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>
2010-11-28target-finalize: libtread_db: support nonstd toolchain setupsMike Frysinger

2010-11-24target-finalize: do not strip libthread_db.soMike Frysinger
For proper threading debug support, the libthread_db.so library cannot be stripped on the target.

2010-11-24auto remove empty /usr/share dirMike Frysinger
Often times, the only reason /usr/share exists is because of documentation installed into it. So once we're done cleaning the docs, attempt to rmdir /usr/share.

2010-11-24linux: strip installed modulesMike Frysinger
The installed kernel modules should have useless build cruft stripped out of them. On my system, a default build went from a very unreasonable 30MB to a normal 3MB (on disk) and from 14MB to 3MB when compressed due to the info stored in the kernel modules alone.

2010-11-19Makefile: handle host packages for make source / make external-depsPeter Korsgaard
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.

2010-11-05Remove support for shared configuration cacheThomas Petazzoni
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.

2010-11-03Makefile: compute the version string for all to useYann E. MORIN
