mkdep(1) — Commands
NAME
mkdep − generate dependency list from a C program
SYNOPSIS
mkdep [-a] [-f depend_file] [-p] [cc_flags] file ...
The mkdep command generates a dependency list file from a C source program.
FLAGS
-aCauses 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.
-f depend_file
Specifies a name for the dependency file; overrides the default file name .depend.
-pInhibits mkdep from appending the suffix .o to the names of object files listed in the output.
DESCRIPTION
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 dependency listings for a given program are included only once in the output.
You can specify C compiler flags by including them in the command line; mkdep passes all unrecognized flags through to the compiler.
By default, mkdep writes to a file named .depend; use the −f flag to specify an alternative output file name.
EXAMPLES
The following example illustrates the use of mkdep with the −p option:
% cat hello.c
#include <stdio.h>
main() {
printf("%s0,"Hello World!");
}
% 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
hello: /usr/include/machine/machtime.h
