lorder(1)         (Software Generation System Utilities)          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; 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.  Note that the link editor ld is capable of multiple
         passes over an archive in the portable archive format [see ar(4)] and
         does not require that lorder be used when building an archive.  The
         usage of the lorder command may, however, allow for a 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                usually /var/tmp but can be redefined by
                               setting the environment variable TMPDIR [see
                               tempnam() in tmpnam(3S)].

   SEE ALSO
         ar(1), ld(1), tsort(1), tempnam(3S), tmpname(3S), ar(4).

   NOTES
         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.
