LORDER(1)                                               LORDER(1)



     NAME
          lorder - find ordering relation for an object library

     SYNOPSIS
          lorder file ...

     DESCRIPTION
          The input is one or more object or library archive files
          [see ar(1)].  The standard output is a list of pairs of
          object file or archive member names, meaning that the first
          file of the pair refers to external identifiers defined in
          the second.  The output may be processed by tsort(1) to find
          an ordering of a library suitable for one-pass access by
          ld(1).  Note that the link editor ld(1) is capable of
          multiple passes over an archive in the portable archive
          format [see ar(4)] and does not require that lorder(1) be
          used when building an archive.  The usage of the lorder(1)
          command may, however, allow for a slightly more efficient
          access of the archive during the link edit process.

          The following example builds a new library from existing .o
          files.

               ar -cr library `lorder *.o | tsort`

     FILES
          TMPDIR/*symref temporary files

          TMPDIR/*symdef temporary files

          TMPDIR is usually /usr/tmp but can be redefined by setting
          the environment variable TMPDIR [see tempnam() in
          tmpnam(3S)].

     SEE ALSO
          ar(1), ld(1), tsort(1), ar(4).

     CAVEAT
          lorder will accept as input any object or archive file,
          regardless of its suffix, provided there is more than one
          input file. If there is but a single input file, its suffix
          must be .o.
