#
|
|
# depsver.mf included in Makefile.am for directories with .deps
|
|
#
|
|
# When building in the same directory with sources that change over
|
|
# time, such as when tracking using bk, the .deps files can become
|
|
# stale with respect to moved, deleted, or superceded headers. Most
|
|
# commonly, this would exhibit as make reporting a failure to make a
|
|
# header file which is no longer in the location given. To address
|
|
# this issue, we use a deps-ver file which is updated with each change
|
|
# that breaks old .deps files. A copy of deps-ver is made into
|
|
# $(DEPDIR) if not already present. If $(DEPDIR)/deps-ver is present
|
|
# with different contents than deps-ver, we make clean to ensure all
|
|
# .o files built before the incompatible change are rebuilt along with
|
|
# their updated .deps files, then remove $(DEPDIR) and recreate it as
|
|
# empty stubs.
|
|
#
|
|
# It is normal when configured with --disable-dependency-tracking for
|
|
# the DEPDIR to not have been created. For this reason, we use the
|
|
# intermediate target .deps-ver, which invokes make recursively if
|
|
# DEPDIR exists.
|
|
#
|
|
# If you modify depsver.mf, please make the changes to the master
|
|
# copy, the one in sntp is copied by the bootstrap script from it.

|
# This comment block follows rather than leads the related rules so that
|
|
# it stays with it in the generated Makefile.in and Makefile.
