NAME

mkdep — construct Makefile dependency list

SYNOPSIS

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.

-f file

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.
