LORDER(1)            INTERACTIVE UNIX System            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, meaning that 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(1).  Note that the link editor ld(1) is capable of multi-
               ple 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.  The usage of the lorder(1) command
               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)].

          SEE ALSO
               ar(1), ld(1), tsort(1), ar(4).

          CAVEAT
               The lorder command 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.
