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.
Regards,
Yann.
