RANLIB(1) GNU Development Tools RANLIB(1)
NAME
ranlib - generate an index to an archive
SYNOPSIS
ranlib [--plugin name] [-DhHvVt] archive
DESCRIPTION
ranlib generates an index to the contents of an archive and stores it in
the archive. The index lists each symbol defined by a member of an
archive that is a relocatable object file.
You may use nm -s or nm --print-armap to list this index.
An archive with such an index speeds up linking to the library and
allows routines in the library to call each other without regard to
their placement in the archive.
The GNU ranlib program is another form of GNU ar; running ranlib is
completely equivalent to executing ar -s.
OPTIONS
-h
-H
--help
Show usage information for ranlib.
-v
-V
--version
Show the version number of ranlib.
-D Operate in deterministic mode. The symbol map archive member's
header will show zero for the UID, GID, and timestamp. When this
option is used, multiple runs will produce identical output files.
If binutils was configured with --enable-deterministic-archives,
then this mode is on by default. It can be disabled with the -U
option, described below.
-t Update the timestamp of the symbol map of an archive.
-U Do not operate in deterministic mode. This is the inverse of the -D
option, above: the archive index will get actual UID, GID,
timestamp, and file mode values.
If binutils was configured without --enable-deterministic-archives,
then this mode is on by default.
@file
Read command-line options from file. The options read are inserted
in place of the original @file option. If file does not exist, or
cannot be read, then the option will be treated literally, and not
removed.
Options in file are separated by whitespace. A whitespace character
may be included in an option by surrounding the entire option in
either single or double quotes. Any character (including a
backslash) may be included by prefixing the character to be included
with a backslash. The file may itself contain additional @file
options; any such options will be processed recursively.
