LORDER(1)                            SysV                            LORDER(1)



NAME
     lorder - find ordering relation for an object library

SYNOPSIS
     lorder file . . .

DESCRIPTION
     Input is one or more object or library archive files [see ar(1)].
     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.  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. 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 .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)].

CAVEAT
     lorder accepts 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.
