MKDEP(1) BSD General Commands Manual MKDEP(1)NAME
mkdep -- construct Makefile dependency list
SYNOPSIS
mkdep [-ap] [-f file] [flags] file ...
DESCRIPTION
The mkdep utility takes a set of flags for the C compiler and a list of C source files as arguments and constructs a set of include file
dependencies which are written into the file ``.depend''. An example of its use in a Makefile might be:
CFLAGS= -O -I../include
SRCS= file1.c file2.c
depend:
mkdep ${CFLAGS} ${SRCS}
where the macro SRCS is the list of C source files and the macro CFLAGS is the list of flags for the C compiler.
The user has the ability to change the preprocessor and preprocessor options used. For instance, to use gcc as the preprocessor and to
ignore system headers, one would use
depend:
env MKDEP_CPP="gcc -E" MKDEP_CPP_OPTS=-MM mkdep
${CFLAGS} ${SRCS}
The options are as follows:
-a Append to the output file, so that multiple mkdep's may be run from a single Makefile.
-f Write the include file dependencies to file, instead of the default ``.depend''.
-p Cause mkdep to produce dependencies of the form:
program: program.c
so that subsequent makes will produce program directly from its C module rather than using an intermediate .o module. This is useful
for programs whose source is contained in a single module.
ENVIRONMENT
CC Specifies the C compiler to use. The specified compiler is expected to have options consistent with the GNU C compiler.
MKDEP_CPP Specifies the preprocessor to use. The default is "${CC} -E".
MKDEP_CPP_OPTS Specifies the non-CFLAGS options for the preprocessor. The default is "-M".
FILES
.depend File containing list of dependencies.

ccmakedep - create dependencies in makefiles using a C compiler
SYNOPSIS
ccmakedep [ cpp-flags ] [ -wwidth ] [ -smagic-string ] [ -fmakefile ] [ -oobject-suffix ] [ -v ] [ -a ] [ -cccompiler ] [ -- options -- ]
sourcefile ...
DESCRIPTION
The ccmakedep program calls a C compiler to preprocess each sourcefile, and uses the output to construct makefile rules describing their
dependencies. These rules instruct make(1) on which object files must be recompiled when a dependency has changed.
By default, ccmakedep places its output in the file named makefile if it exists, otherwise Makefile. An alternate makefile may be speci-
fied with the -f option. 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 doesn't find it, the program will append the string to the makefile
and place the output after that.
EXAMPLE
Normally, ccmakedep will be used in a makefile target so that typing 'make depend' will bring the dependencies up to date for the makefile.
For example,
SRCS = file1.c file2.c ...
CFLAGS = -O -DHACK -I../foobar -xyz
depend:
ccmakedep -- $(CFLAGS) -- $(SRCS)
OPTIONS
The program will ignore any option that it does not understand, so you may use the same arguments that you would for cc(1), including -D
and -U options to define and undefine symbols and -I to set the include path.
-a Append the dependencies to the file instead of replacing existing dependencies.
-cccompiler
Use this compiler to generate dependencies.
-fmakefile
Filename. 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.
-sstring
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".
-v Be verbose: display the C compiler command before running it.
-- options --
If 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). -D, -I, and -U options
appearing between the pair of double hyphens are still processed normally.
