NAME



mkdep

 - construct Makefile dependency list

SYNOPSIS

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

DESCRIPTION

The 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:

-a

Append to the output file, so that multiple 's may be run from a single Makefile.

-f

Write the include file dependencies to file instead of the default ``.depend''.

-p

Cause 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.

ENVIRONMENT

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