NAME
mkdep -- construct Makefile dependency list SYNOPSIS
mkdep [-aDdopq] [-f file] [-s suffixes] -- [flags] file ... DESCRIPTION
mkdep 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 options are as follows: -a Append to the output file, so that multiple mkdep's may be run from a single Makefile. -D Post process (as -d) but read the list of filenames from stdin. -d Post process and merge previously created (for example by ``cc -MD x.c'') depend files into a single file. -f Write the include file dependencies to file, instead of the default ``.depend''. -o Add an additional .OPTIONAL line for each dependent file. -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. -p is equivalent to specifying a null suffix with -s. -q Do not print a warning for inaccessible files when -d is given. -s Expand each target filename to a list, replacing the '.o' suffix with each element of suffixes. The list of suffixes may be space or comma separated. FILES
.depend File containing list of dependencies. SEE ALSO
cc(1), cpp(1), make(1) HISTORY
The mkdep command appeared in 4.3BSD-Tahoe. BUGS
Some characters special to make(1), most notably the comment character, are not escaped correctly if they appear in file names. This can lead to unparseable output or silently cause dependencies to be lost. BSD

NAME
gccmakedep - create dependencies in makefiles using 'gcc -M' SYNOPSIS
gccmakedep [ -sseparator ] [ -fmakefile ] [ -a ] [ -- options -- ] sourcefile ... DESCRIPTION
The gccmakedep program calls 'gcc -M' to output makefile rules describing the dependencies of each sourcefile, so that make(1) knows which object files must be recompiled when a dependency has changed. By default, gccmakedep 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, gccmakedep will be used in a makefile target so that typing 'make depend' will bring the dependencies up to date for the make- file. For example, SRCS = file1.c file2.c ... CFLAGS = -O -DHACK -I../foobar -xyz depend: gccmakedep -- $(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 gcc(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. -fmakefile Filename. This allows you to specify an alternate makefile in which gccmakedep 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 gccmakedep to look for in the makefile. The default is "# DO NOT DELETE". -- options -- If gccmakedep 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, gccmakedep 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.
