<p><code>ranlib</code> 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.
</p>
<p>You may use &lsquo;<samp>nm -s</samp>&rsquo; or &lsquo;<samp>nm --print-armap</samp>&rsquo; to list this index.
</p>
<p>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.
</p>
<p>The <small>GNU</small> <code>ranlib</code> program is another form of <small>GNU</small> <code>ar</code>; running
<code>ranlib</code> is completely equivalent to executing &lsquo;<samp>ar -s</samp>&rsquo;.
See <a href="ar.html#ar">ar</a>.

<p>Operate in <em>deterministic</em> mode.  The symbol map archive member&rsquo;s
header will show zero for the UID, GID, and timestamp.  When this
option is used, multiple runs will produce identical output files.
</p>
<p>If <samp>binutils</samp> was configured with
<samp>--enable-deterministic-archives</samp>, then this mode is on by
default.  It can be disabled with the &lsquo;<samp>-U</samp>&rsquo; option, described
below.

<p>Do <em>not</em> operate in <em>deterministic</em> mode.  This is the
inverse of the &lsquo;<samp>-D</samp>&rsquo; option, above: the archive index will get
actual UID, GID, timestamp, and file mode values.
</p>
<p>If <samp>binutils</samp> was configured <em>without</em>
<samp>--enable-deterministic-archives</samp>, then this mode is on by
default.
