34.Sh NAME
35.Nm lorder
36.Nd list dependencies for object files
37.Sh DEPRECATION NOTICE
38.Nm
39is obsolete and may not be present in
40.Fx 14
41and later.
42.Sh SYNOPSIS
43.Nm
44.Ar
45.Sh DESCRIPTION
46The
47.Nm
48utility uses
49.Xr nm 1
50to determine interdependencies in the list of object files
51and library archives
52specified on the command line.
53The
54.Nm
55utility outputs a list of file names where the first file contains a symbol
56which is defined by the second file.
57.Pp
58The output is normally used with
59.Xr tsort 1
60when a library is created to determine the optimum ordering of the
61object modules so that all references may be resolved in a single
62pass of the loader.
63.Pp
64When linking static binaries,
65.Nm
66and
67.Xr tsort 1
68can be used to properly order library archives automatically.
69.Pp
70The use of
71.Nm
72is not required by contemporary linkers, and
73.Nm
74may be removed from a future version of
75.Fx .
