* kconfig: support DOS line endingsMatthew Wilcox2006-09-251-2/+6
| | | | | | | | | | Kconfig doesn't currently handle config files with DOS line endings. While these are, of course, an abomination, etc, etc, it can be handy to not have to convert them first. It's also a tiny patch and even adds support for lines ending in just \r or even \n\r. Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
* kconfig: correct oldconfig for unset choice optionsRoman Zippel2006-08-011-1/+1
| | | | | | | | | oldconfig currently ignores unset choice options and doesn't ask for them. Correct the SYMBOL_DEF_USER flag of the choice symbol to be only set if it's set for all values. Signed-off-by: Roman Zippel <zippel@linux-m68k.org> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
* kconfig: enhancing accessibility of lxdialogSamuel Thibault2006-07-011-2/+5
| | | | | | | | | | | | Some fix that I forgot for good accessibility of lxdialog (the cursor should always be left at the focus location): Have the checklist display the currently highlighted entry last, for having the cursor left on it (rather than on the last line of the list).

| | | | | | | | | | | | This makes it possible to change two options which were hardcoded sofar. 1. Any symbol can now take the role of CONFIG_MODULES 2.

* kconfig: integrate split config into silentoldconfigRoman Zippel2006-06-092-3/+121
| | | | | | | | | | | | | Now that kconfig can load multiple configurations, it becomes simple to integrate the split config step, by simply comparing the new .config file with the old auto.conf (and then saving the new auto.conf). A nice side effect is that this saves a bit of disk space and cache, as no data needs to be read from or saved into the splitted config files anymore (e.g. include/config is now 648KB instead of 5.2MB).

* kconfig: fix .config dependenciesRoman Zippel2006-06-094-55/+143
| | | | | | | | | | | | | | | | | | | | | | This fixes one of the worst kbuild warts left - the broken dependencies used to check and regenerate the .config file. This was done via an indirect dependency and the .config itself had an empty command, which can cause make not to reread the changed .config file. Instead of this we generate now a new file include/config/auto.conf from .config, which is used for kbuild and has the proper dependencies. It's also the main make target now for all files generated during this step (and thus replaces include/linux/autoconf.h). This also means we can now relax the syntax requirements for the .config file and we don't have to rewrite it all the time, i.e. silentoldconfig only writes .config now when it's necessary to keep it in sync with the Kconfig files and even this can be suppressed by setting the environment variable KCONFIG_NOSILENTUPDATE, so the update can (and must) be done manually.

* kbuild: change kbuild to not rely on incorrect GNU make behaviorPaul Smith2006-03-062-5/+5
| | | | | | | | | | | | | | | | | | | | The kbuild system takes advantage of an incorrect behavior in GNU make. Once this behavior is fixed, all files in the kernel rebuild every time, even if nothing has changed. This patch ensures kbuild works with both the incorrect and correct behaviors of GNU make. For more details on the incorrect behavior, see: http://lists.gnu.org/archive/html/bug-make/2006-03/msg00003.html Changes in this patch: - Keep all targets that are to be marked .PHONY in a variable, PHONY. - Add .PHONY: $(PHONY) to mark them properly. - Remove any $(PHONY) files from the $? list when determining whether targets are up-to-date or not.

* kbuild: small update of allnoconfig descriptionJesper Juhl2006-02-271-1/+1
| | | | | | | | | | | | | 'allnoconfig' is described by 'make help' as a "minimal config", that's not strictly correct. To be pedantic, a minimal config would be one where EMBEDDED was set to Y and most things therein disabled etc. Simply answering 'no' to all options does not give a minimal config. A better description of allnoconfig is that it answers all options with 'no'. This patch updates the description.

| * kconfig: fix /dev/null breakageSam Ravnborg2006-01-212-7/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While running "make menuconfig" and "make mrproper" some people experienced that /dev/null suddenly changed permissions or suddenly became a regular file. The main reason was that /dev/null was used as output to gcc in the check-lxdialog.sh script and gcc did some strange things with the output file; in this case /dev/null when it errorred out. Following patch implements a suggestion from Bryan O'Sullivan <bos@serpentine.com> to use gcc -print-file-name=libxxx.so. Also the Makefile is adjusted to not resolve value of HOST_EXTRACFLAGS and HOST_LOADLIBES until they are actually used. This prevents us from calling gcc when running make *clean/mrproper Thanks to Eyal Lebedinsky <eyal@eyal.emu.id.au> and Jean Delvare <khali@linux-fr.org> for the first error reports.
