<ul class="simple">
<li><p><code class="docutils literal notranslate"><span class="pre">--enable-ld-version-script</span></code>: New <strong class="program">configure</strong> option to
enable shared library symbol versioning on ELF-based systems
(e.g. Linux and FreeBSD) which use the GNU linker.  This
allows multiple major versions of libtiff to be loaded
simultaneously into the same application or library without
conflict, as long as all libtiffs involved are built with
versioned symbols.  This option is not enabled by default.</p></li>
