lorder(1) User Commands lorder(1)NAMElorder - find ordering relation for an object or library archive
SYNOPSISlorder 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 ar‐
chive member names; the first file of the pair refers to external iden‐
tifiers 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 ar‐
chive in the portable archive format (see ar.h(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 set‐
ting the environment variable TMPDIR (see
tempnam() in tmpnam(3C))

SEE ALSOar(1), ld(1), tsort(1), tmpnam(3C), ar.h(3HEAD), attributes(5)NOTESlorder 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.
