Re: [kbuild-devel] [rfe] easier customization of kconfig for non-Linux projects
Hello all!
Sorry to jump into the discussion, but...

The intent with this is clear but the solution you suggest albeit simple
does not really match where we could end up with kconfig.
Recently Roman added support for options in the kconfig language
and I would assume we could deal with most of this just using options.
One example could be to support options for the mainmenu entrye like this:
mainmenu Busybow config system
option project=Busybox
option version=$VERSION = Where '$' signify an environment variable
I would rather suggest a kind of 'namespace' thing. This way, one could use
the kconfig language for a project (eg. buildroot) and include sub-Kconfig
files from other sub-projects (eg. kernel), thus making all configurable
from the same menu.
Something like (syntax proposal):
8
mainmenu Buildroot config system
option prefix== prefix to config options
config foo = foo=y/ # foo is not set
blah blah blah...
namespace Buildroot options
option project=Buildroot
option version=${VERSION} = To avoid $VERSION_test ambiguity
option prefix=BR2_= prefix to config options
config bar = BR2_bar=y / # BR2_bar is not set
blah blah blah...
endnamespace
namespace Linux Kernel options
option project=Linux
option version=...
option prefix=CONFIG_
include ${BR2_KERNEL_DIR}/arch/${BR2_ARCH]/Kconfig
endnamespace
8
Then with a simple grep -E '^CONFIG_' one can easily extract the kernel
options from the others.
We _may_ need to support nested namespaces also, concatenating the prefixes.
I once tried to do such thing, but I'm lacking good lex/yacc fu, and I
miserably failed... :-(
Comments?

[kbuild-devel] RFC - new feature - 'string' without double quotes
Hi! I'm adding a new statement to kbuild that will allow one to declare a string that will not contain double quotes. Current state: = kbuild adds double quotes in strings when crating the .config file. This file is parsed both by a bash script and included by a Makefile. Problem: === Suppose config.in contains: string Where is it MY_PATH /some/path it would give a .config with: MY_PATH=/some/path when included in a Makefile with these rule: include .config target: $(MY_PATH)/some.file do_smthg --with $^ --out $@ This construct fails miserably because $(MY_STRING)/some.file will expand to /some/path/some.file which make strictly interprets as the name of a file that starts with a double quote, followed by the litteral /some/path, again a double quote, and finally /some.file, which is obviously not what we were expecting. Solution (as I see it): == Hmm, looks there's nothing like that in the ML archives... Neither did I find something on google, and I tried pretty hard... So, here's what I did: Add a statement that allows string to not be double-quote-enclosed. Because there can be special chars in the string (such as spaces), escape those chars. So far, I've made Configure, Menuconfig and config-language.txt aware of the two new statements 'path' and 'define_path' (that behave the same as string, but omitting the surrounding double quotes, and escaping chars [well, only space is escaped for now]). === Is this of a real matter for kbuild, or am I the only one needing a solution? Regarding kconfig.tk, I'm a bit reluctant to touch the code (plus I mainly use menuconfig). Would the new statements be really wanted, is anybody willing to give a hand on the subject. As for mconfig, I haven't yet looked into it... Maybe, maybe late in the WE... I supposed it the way 2.6 goes... Anyway, here's a first patch against 2.4.31. Please comment.
