ranlib






ranlib − generate index to 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.
