mkdep - generate dependency list from a C program
mkdep [-a] [-f depend_file] [-p] [cc_options] file...
The mkdep command generates a dependency list file from a C source program.
-a Causes mkdep to append its output to the end of the dependency file
instead of creating a new dependency file. If the dependency file does
not exist, mkdep creates it.
Specifies a name for the dependency file; overrides the default file
-p Inhibits mkdep from appending the suffix .o to the names of object
files listed in the output.
The mkdep command uses cc(1) to compile a list of dependency files required
to build the named C program file or files. The list is formatted so that
it is suitable for inclusion into a makefile for make(1). Duplicate depen-
dency listings for a given program are included only once in the output.
You can specify C compiler options by including them in the command line;
mkdep passes all unrecognized options through to the compiler.
By default, mkdep writes to a file named .depend; use the -f option to
specify an alternative output file name.
The following example illustrates the use of mkdep with the -p option:
% cat hello.c
% mkdep -p -f hello.depend hello.c
% cat hello.depend
hello: hello.c /usr/include/stdio.h /usr/include/standards.h
hello: /usr/include/sys/types.h /usr/include/standards.h
hello: /usr/include/mach/machine/vm_types.h /usr/include/sys/limits.h
hello: /usr/include/standards.h /usr/include/machine/machlimits.h
hello: /usr/include/sys/syslimits.h /usr/include/float.h
hello: /usr/include/standards.h /usr/include/fp_class.h
Commands: cc(1), make(1)
