mkdepconstruct Makefile dependency list

mkdep [-ap] [-f file] [flags] file ...

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:

Append to the output file, so that multiple mkdep's may be run from a single Makefile.
Write the include file dependencies to file, instead of the default ``.depend''.
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.

Specifies the C compiler to use. The specified compiler is expected to have options consistent with the GNU C compiler.
Specifies the preprocessor to use. The default is "${CC} -E".
Specifies the non-CFLAGS options for the preprocessor. The default is "-M".

.depend
File containing list of dependencies.

The mkdep command appeared in 4.3BSD-Tahoe.
