ccmakedep program calls a C compiler to preprocess each
sourcefile, and uses the output to construct
makefile rules describing their dependencies.
These rules instruct
on which object files must be recompiled when a dependency has changed.
ccmakedep places its output in the file named
makefile if it exists, otherwise
Makefile. An alternate makefile may be specified with the
It first searches the makefile for a line beginning with
# DO NOT DELETE
or one provided with the
-s option, as a delimiter for the dependency output.
If it finds it, it will delete everything following this up to the end of
the makefile and put the output after this line.
If it doesnt find it, the program will append the string to the makefile
and place the output after that.
ccmakedep will be used in a makefile target so that typing make depend will bring
the dependencies up to date for the makefile.
SRCS = file1.c file2.c ...
CFLAGS = -O -DHACK -I../foobar -xyz
ccmakedep -- $(CFLAGS) -- $(SRCS)
The program will ignore any option that it does not understand, so you may
use the same arguments that you would for
-U options to define and undefine symbols and
-I to set the include path.
Append the dependencies to the file instead of replacing existing
Use this compiler to generate dependencies.
This allows you to specify an alternate makefile in which
ccmakedep can place its output.
Specifying - as the file name (that is,
-f-) sends the output to standard output instead of modifying an existing file.
Starting string delimiter.
This option permits you to specify a different string for
ccmakedep to look for in the makefile.
The default is # DO NOT DELETE.
Be verbose: display the C compiler command before running it.
-- options -- |
ccmakedep encounters a double hyphen (--) in the argument list, then any
unrecognized arguments following it will be silently ignored.
A second double hyphen terminates this special treatment.
In this way,
ccmakedep can be made to safely ignore esoteric compiler arguments that might
normally be found in a CFLAGS
make macro (see the
EXAMPLE section above).
-U options appearing between the pair of double hyphens are still processed
