1.1 deraadt 45: .Sh DESCRIPTION
1.4 aaron 46: .Nm
1.1 deraadt 47: takes a set of flags for the C compiler and a list
48: of C source files as arguments and constructs a set of include
1.4 aaron 49: file dependencies which are written into the file
50: .Pa .depend .
1.1 deraadt 51: An example of its use in a Makefile might be:
52: .Bd -literal -offset indent
53: CFLAGS= -O -I../include
54: SRCS= file1.c file2.c
55:
56: depend:
57: mkdep ${CFLAGS} ${SRCS}
58: .Ed
59: .Pp
60: where the macro SRCS is the list of C source files and the macro
61: CFLAGS is the list of flags for the C compiler.
62: .Pp
63: The options are as follows:
64: .Bl -tag -width Ds
65: .It Fl a
66: Append to the output file,
67: so that multiple
68: .Nm mkdep Ns 's
69: may be run from a single Makefile.
1.3 aaron 70: .It Fl f Ar file
1.4 aaron 71: Write the include file dependencies to
1.1 deraadt 72: .Ar file ,
1.4 aaron 73: instead of the default
74: .Pa .depend .
1.1 deraadt 75: .It Fl p
76: Cause
1.4 aaron 77: .Nm
1.1 deraadt 78: to produce dependencies of the form:
79: .Bd -literal -offset indent
80: program: program.c
81: .Ed
82: .Pp
83: so that subsequent makes will produce
84: .Ar program
85: directly from its C module rather than using an intermediate
86: .Pa \&.o
87: module.
88: This is useful for programs whose source is contained in a single
89: module.
