NAME

lorder − find ordering relation for an object library

SYNOPSIS

lorder file ... 

DESCRIPTION

The input is one or more object or library archive (see ar(1)) files.  The standard output is a list of pairs of object file names; specifically the first file of the pair refers to external identifiers defined in the second pair.  The output may be processed by tsort(1) to find an ordering of a library suitable for one-pass access by ld(1).

This following one-liner intends to build a new library from existing ‘.o’ files. 

ar cr library `lorder \(**.o | tsort`

The need for lorder may be vitiated by use of ranlib(1), which converts an ordered archive into a randomly accessed library.

FILES

\(**symref, \(**symdef
nm(1), sed(1), sort(1), join(1)

SEE ALSO

tsort(1), ld(1), ar(1), ranlib(1)

BUGS

The names of object files, in and out of libraries, must end with ‘.o’; otherwise, nonsense results.
