RANLIB(1)                 GNU Development Tools                RANLIB(1)

NAME         top

       ranlib - generate an index to an archive

SYNOPSIS         top

       ranlib [--plugin name] [-DhHvVt] archive

DESCRIPTION         top

       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         top

           Show usage information for ranlib.

           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

       -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

           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.
