<h4 class="subsection">3.17.41 VxWorks Options</h4>

<p><a name="index-VxWorks-Options-2065"></a>
The options in this section are defined for all VxWorks targets. 
Options specific to the target hardware are listed with the other
options for that target.

     <dl>
<dt><code>-mrtp</code><dd><a name="index-mrtp-2066"></a>GCC can generate code for both VxWorks kernels and real time processes
(RTPs).  This option switches from the former to the latter.  It also
defines the preprocessor macro <code>__RTP__</code>.

     <br><dt><code>-non-static</code><dd><a name="index-non_002dstatic-2067"></a>Link an RTP executable against shared libraries rather than static
libraries.  The options <samp><span class="option">-static</span></samp> and <samp><span class="option">-shared</span></samp> can
also be used for RTPs (see <a href="Link-Options.html#Link-Options">Link Options</a>); <samp><span class="option">-static</span></samp>
is the default.

     <br><dt><code>-Bstatic</code><dt><code>-Bdynamic</code><dd><a name="index-Bstatic-2068"></a><a name="index-Bdynamic-2069"></a>These options are passed down to the linker.  They are defined for
compatibility with Diab.

     <br><dt><code>-Xbind-lazy</code><dd><a name="index-Xbind_002dlazy-2070"></a>Enable lazy binding of function calls.  This option is equivalent to
<samp><span class="option">-Wl,-z,now</span></samp> and is defined for compatibility with Diab.

     <br><dt><code>-Xbind-now</code><dd><a name="index-Xbind_002dnow-2071"></a>Disable lazy binding of function calls.  This option is the default and
is defined for compatibility with Diab.
