# This module provides automagic dependency generation along the
|
|
# lines suggested in the GNU make.info
|
|
|
|
# set MKDEP_MK=auto.dep.mk and dep.mk will include us
|
|
|
|
# This version differs from autodep.mk, in that
|
|
# we use ${.TARGET:T}.d rather than ${.TARGET:T:R}.d
|
|
# this makes it simpler to get the args to -MF and -MT right
|
|
# and ensure we can simply include all the .d files.
|
|
#
|
|
# However suffix rules do not work with something like .o.d so we
|
|
# don't even try to handle 'make depend' gracefully.
|
|
# dep.mk will handle that itself.
