.SH NAME
mkdep \- file dependencies generator
.SH SYNOPSIS
.TP
.B mkdep
[-h] [-a] [-k]
.br
[-c<compiler>] [-l<lib>] [-d<dir>]
.br
[-p<paths>] [-i<path>] [-s<var>=<path>] [-t<suffix>]
.br
[-I/Y<dir>] [-D/U<macro>] [-o<file>] <files>
.PP
.SH DESCRIPTION
.I mkdep
generates dependencies for makefile through a preprocessor on standard
output or at the end of a specified file (e.g. makefile).
Options are read and interpreted in sequence, so you can switch them for
different files.
.br
For instance:
.nf
mkdep -cgcc -llibm.a sin.c cos.c -cg++ -llibM.a Matrix.cc
.fi
.PP
.SH OPTIONS
.TP
.I -h
Help. Display a summary of options.
.PP
.TP
.I -a
By default, dependencies of system files
are not generated. This option forces
.B mkdep
to generate
.I all
dependencies.
.PP
.TP
.I -k
Compact output mode. Dependencies are generated on one line per
target, default mode generates one line per dependency.
.PP
.TP
.I -c<compiler>
Specifies the compiler (gcc, cc...) to use as the preprocessor. By
default, this is set to
.B gcc.
In fact,
.B mkdep
use the option -E of this compiler (so you can specify
.I any
compiler which has this option -E).
This option resets also -I, -Y, -D, -U, -d and -l flags.
.PP
.TP
.I -i<path>
Ignore all dependencies beginning with the given path (and so allows
some filtering of your local standard include).
.PP
.TP
.I -l<lib>
This option precises that the target is an object file of a library.
So the dependencies are generated with the format <lib>(%.o).
.PP
.TP
.I -d<dir>
This option precises that the target is localised in the specified
directory. The dependencies are generated with the format <dir>/%.o.
.PP
.TP
-o<file>
By default, dependencies are generated on standard output. You can
specify a file (e.g. Makefile) with this option, dependencies will
be generated at the end of this file and replace previous dependencies
(if any). This generation is also incremental and unmodified
dependencies are preserved by
.B mkdep.
.PP
.TP
.I -p<paths>
This option specifies a set of paths where the source files must be
searched. This corresponds to the variable VPATH of many makefiles and
is usually used as -p$(VPATH) in them.
.PP
.TP
.I -t<suffix>
Defines the target suffix. By default, all targets are assumed to have
the ".o" suffix (C compiling).
.PP
.TP
.I -s<var>=<path>
Replace in dependencies the given path by $(var) to allow genericity
in the generated dependencies.
.PP
.TP
.I -I<dir> -D<macro> -Y<dir> -U<macro>
These options are given to the prepocessor that generates the
dependencies.
