NAME
mkdep - construct Makefile dependency list
SYNOPSIS
mkdep [-ap] [-f file] [flags] file [...]
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.
