lorder(1)                USER COMMANDS                  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)].

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.
