Re: [kbuild-devel] Mucking with assembly files

This means overriding some of kbuild's implicit rules, and I'm not sure how to do that cleanly. Is this still relevant considering you adopted the -funit-at-a-time proposal?

Re: [kbuild-devel] help text on choices

It is a menuconfig limitation. xconfig shows the helptext as one would expect it to do. See attached screenshot.

As part of my kbuild/kconfig pre-rewrite info collecting... whatever :) I did asm-offsets build rewrite RFC four week ago: http://mid.gmane.org/[EMAIL PROTECTED] You may be interested in it. But Sam is busy, nothing happend since then. Just returned from a nice 2 week vacation with no Internet access and no computer turned on (not counting the GPS). And still lacking behind on other stuff too. Sam - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML. No limits.
