# The include file <bsd.obj.mk> handles creating 'obj' directory
|
|
# and cleaning up object files, log files etc.

|
|
# +++ variables +++
|
|
#
|
|
# CLEANFILES Additional files to remove for the clean and cleandir targets.
|
|
#
|
|
# MAKEOBJDIR Specify somewhere other than /usr/obj to root the object
|
|
# tree. Note: MAKEOBJDIR is an *enviroment* variable
|
|
# and does work proper only if set as enviroment variable,
|
|
# not as global or command line variable! [obj]
|
|
#
|
|
# E.g. use `env MAKEOBJDIR=/somewhere/obj make'
|
|
#
|
|
# NOOBJ Do not create build directory in object tree.
|
|
#
|
|
# OBJLINK Create a symbolic link from ${.TARGETOBJDIR} to ${.CURDIR}/obj
|
|
# Note: This BREAKS the read-only src tree rule!
