[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH 1/2] build: clean up kclean and distclean for kernel
* Don't delete non-existent %.tar.bz2 in buildconfigs/Rules.mk's %-mrproper
* Add a mrpropper target to buildconfigs/mk.linux-2.6-xen, and
have this delete the local tarball
- This should also delete the local patch, if there is one, but I am not
sure how to do this with the current incarntation of the code, and I
will post a subsequent patch which makes this easier and effects this
chang. As there currently is no local patch this is not a big deal at
this moment. (Horms)
* Make distclean depend on kdekete, rather than calling delete target by
hand
* Stop kclean from erroring out if the kernel directory doesn't exist
* Remove patches/*/.makedep in top level Makefile rather than in
buildconfigs/Rules.mk, as calling rules in the latter causes
patches/*/.make to be created (Magnus)
