ranlib - generate index to archive.
ranlib [ --plugin name
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
is completely equivalent to executing ar -s
- Show usage information for ranlib.
- Show the version number of ranlib.
- 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
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.
- Update the timestamp of the symbol map of an archive.
- 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
- 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.
