# To generate the dependency files:

|

# - Use the compiler's "-MMD" option to generate output of the form
|
|
# "foo.o : foo.c foo.h bar.h".
|
|
#
|
|
# - Also, "-MMD" will cause the compiler to name the target as if it were in the
|
|
# current directory ("foo.o: "); use -MT to rename the target in the output
|
|
# directory ("_out/Linux_x86/foo.o: ") so that the target actually applies to
|
|
# the object files produced in the build.
|
|
#
|
|
# - Use -MP to generate a phony target for each of those prerequisites (except
|
|
# the source file being compiled). E.g.,
|
|
# "foo.o : foo.c foo.h bar.h
|
|
# foo.h:
|
|
# bar.h:"
|
|
# so that the makefile can handle incremental builds after a prerequisite has
|
|
# been deleted from source control.
|

# - Use sed to remove the source file from the list of prerequisties in the

# above, so that the makefile can handle increment builds after the source has

|
# moved from one directory to another. The DEFINE_OBJECT_RULE macro spells
