lorder(1)

NAME

     lorder - find ordering relation for  an  object  or  library
     archive

SYNOPSIS

     lorder filename...

DESCRIPTION

     The input is one or more object or library archive filenames
     (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(3HEAD)) 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(3C))

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.

     The length of the filename for TMPDIR is limited to whatever
     sed allows.
