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.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 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.
