[Buildroot] new way to rebuld just the target root?

[Buildroot] new way to rebuld just the target root?

[Igor Serebryany]

hi, 

	i've asked this question before, but it seems the structure of the
	buildroot output directories has changed since I last upgraded. 

	using 2009.08, i would do the following to have buildroot rebuild
	ONLY the target filesystem:

	* remove everything in project_build_*arch*/*myname*/autotools-stamps
	* remove the project_build_*arch*/*myname*/root directory
	* remove the project_build_*arch*/*myname*/.root file

	however, this directory structure doesn't exist anymore, and just
	removing 'output/target' and 'output/staging' doesn't seem to
	work/causes problems.

	is there a new way to rebuild JUST the target filesystem?

addendum: i can see that packages often have a .stamp_target_installed
file, and I wouldn't mind going through and deleting all of those, but
how do i get the entire target directory re-created, including copying
from skeleton?

[Buildroot] new way to rebuld just the target root?

Hi Igor,

I've added this rule to the toplevel Makefle:

clean-target:
        rm -rf $(TARGET_DIR) $(STAGING_DIR) $(STAMP_DIR) $(BUILD_DIR)/.root 
$(BUILD_DIR)/*/.stamp_target_installed $(BUILD_DIR)/*/.stamp_staging_installed 
$(BUILD_DIR)/linux-*/.stamp_installed $(BUILD_DIR)/*/.built

It removes the staging dir as well because that doesn't cost so much in terms 
of rebuild-time but keeps quite some problems away.  But it's most likely not 
complete, so I'm not going to post it as a patch.  Serves me quite well 
though.

HTH,
Malte
