2010-07-23kconfig: implement KCONFIG_PROBABILITY for rand{,package}configPeter Korsgaard
rand{,package}config enables configuration options with 50% probability, which isn't always what we want in BR (because the "big" configs take a long time to build and limits the chance of a randconfig detecting a missing dependency), so introduce a KCONFIG_PROBABILITY environment variable to tweak the probability between 0 (all options off) and 100 (all options on). To use, simply set the environment variable before running make or pass it on the make command line - E.G. make randpackageconfig KCONFIG_PROBABILITY=10 Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

2009-08-03kconfig: fix oldconfig to generate .config.cmdThomas Petazzoni
Since the recent update of Kconfig to the Kconfig infrastructure found in 2.6.30 kernels, make oldconfig was broken because it didn't generate the .config.cmd file. This is done by a call to the conf_write_autoconf() function. Moreover, this process was also broken because the conf_get_autoconfig_name() function was reading the environment variable BUILDROOT_AUTOCONF while the main Makefile is passing it as KCONFIG_AUTOCONFIG. We also remove the fallback on "$(BR2_DEPENDS_DIR)/config/auto.conf" since we are not able to expand BR2_DEPENDS_DIR at this point. Therefore, the KCONFIG_AUTOCONFIG envionment variable *must* be set. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

2007-09-12 Watching all the warnings on package/config finally got to me.Ulf Samuelsson
A patch that clears the gcc warnings from config with cast changes only. thanks, I feel better now, Rick Foos <rick@synchromeshcomputing.com>
2007-07-08- silence a cosmetic warning (closes several issues in mantis).Bernhard Reutner-Fischer
This also provides a nice up-to-date filestamp if something got reconfigured (e.g. c++ support got toggled) that can be used in the future to depend accordingly.

2005-03-09Fix /http://bugs.uclibc.org/view.php?id=134Eric Andersen
The configuration utility in package/config/ can look for a default configuration file called 'defconfig' but it's hard coded to look for sysdeps/linux/defconfig. This patch causes the config utility to look in the current working directory for the 'defconfig' file. I use this to provide a default configuration to a new buildroot environment. This way, I can 'svn co' buildroot, copy my defconfig, then make defconfig to use my own default configuration. This fix only changes one line in the confdata.c file to remove the legacy path that was used in Linux, and not needed in buildroot.
