3# The include file <bsd.obj.mk> handles creating 'obj' directory
4# and cleaning up object files, log files etc.
5#
6#
7# +++ variables +++
8#
9# CLEANFILES	Additional files to remove for the clean and cleandir targets.
10#
11# MAKEOBJDIR 	Specify somewhere other than /usr/obj to root the object
12#		tree. Note: MAKEOBJDIR is an *enviroment* variable
13#		and does work proper only if set as enviroment variable,
14#		not as global or command line variable! [obj]
15#
16#		E.g. use `env MAKEOBJDIR=/somewhere/obj make'
17#
18# NOOBJ		Do not create build directory in object tree.
19#
20# OBJLINK	Create a symbolic link from ${.TARGETOBJDIR} to ${.CURDIR}/obj
21#		Note:  This BREAKS the read-only src tree rule!
22#

28#	cleandir:
29#		remove the build directory (and all its contents) created by obj
30#

32#		create build directory.
