|
|
.Sh SYNOPSIS
|
|
.Nm
|
|
.Ar
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility uses
|
|
.Xr nm 1
|
|
to determine interdependencies in the list of object files
|
|
and library archives
|
|
specified on the command line.
|
|
The
|
|
.Nm
|
|
utility outputs a list of file names where the first file contains a symbol
|
|
which is defined by the second file.
|
|
.Pp
|
|
The output is normally used with
|
|
.Xr tsort 1
|
|
when a library is created to determine the optimum ordering of the
|
|
object modules so that all references may be resolved in a single
|
|
pass of the loader.
|
|
.Pp
|
|
When linking static binaries,
|
|
.Nm
|
|
and
|
|
.Xr tsort 1
|
|
can be used to properly order library archives automatically.
|
|
.Sh EXAMPLES
|
|
.Bd -literal -offset indent
|
|
ar cr library.a `lorder ${OBJS} | tsort`
|
|
cc -o foo ${OBJS} `lorder ${STATIC_LIBS} | tsort`
