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