<p>The -static option will avoid the need to ring.dll|ring.so|ring.dylib</p>
<p>But since the stdlib.ring load libraries like (LibCurl, OpenSSL, MySQL, etc)</p>
<p>You will need these libraries!</p>
<p>To avoid the need to these libraries (If you don’t need stdlib classes)</p>
<p>Use stdlibcore.ring instead of stdlib.ring as in the next example</p>
<div class="highlight-ring notranslate"><div class="highlight"><pre><span></span><span class="k">load</span> <span class="s">&quot;stdlibcore.ring&quot;</span>
