MKDEP(@CMD_EXT_U@)

NAME
mkdep - construct Makefile dependency list

SYNOPSIS
mkdep [-ap] [-f depend_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_file, or “.depend” by default. An example of its use in a Makefile might be:

    CFLAGS= -O -DDEBUG -I../include -I.
    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.

If the “-p” option is provided, mkdep produces dependencies of the form “program: program.c” so that subsequent calls to make(@CMD_EXT@) will produce “program” directly from its C module rather than using an intermediate “.o” module. This is useful in directories which contain many programs, each of whose source is contained in a single C module.

The “-a” option causes appending to the output file, so that multiple mkdep 's may be run from a single Makefile.
