RANLIB(1) GNU Development Tools RANLIB(1)
ranlib - generate an index to an archive
ranlib [--plugin name] [-DhHvVt] archive
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.
-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.
ar(1), nm(1), and the Info entries for binutils.
