mkdep - generate dependency list from a C program SYNOPSIS
mkdep [-a] [-f depend_file] [-p] [cc_options] file... The mkdep command generates a dependency list file from a C source program. OPTIONS
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 name Inhibits mkdep from appending the suffix 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 for- matted 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 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 -f option 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 SEE ALSO

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. SEE ALSO
