lorder(1)                      DG/UX R4.11MU05                     lorder(1)


NAME
       lorder - find ordering relation for an object library

SYNOPSIS
       lorder file ...

DESCRIPTION
       Lorder reads each object or archive file and produces a list of pairs
       of object file or archive member names.  The first file of each pair
       refers to external identifiers defined in the second file.

       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) can perform 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.  Using lorder(1) 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 object
       files:

              ar cr library `lorder *.o | tsort`

FILES
       TMPDIR/*symref
                     Temporary file of symbol references

       TMPDIR/*symdef
                     Temporary file of symbol definitions

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