mkdep

BSD mandoc
BSD 4.2

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.
