|
|
|
|
<p>If your implementation already provides ASDF 3 or later (and it should),
|
|
but you want a more recent ASDF version than your implementation provides, then
|
|
you just need to ensure the more recent ASDF is installed in a configured path,
|
|
like any other system.
|
|
We recommend you download an official tarball or checkout a release from git into
|
|
<samp>~/common-lisp/asdf/</samp>.
|
|
(see <a href="Configuring-ASDF-to-find-your-systems.html">Configuring ASDF to find your systems</a>).
|
|
</p>
|
|
<p>Once the source code for ASDF is installed,
|
|
you don’t need any extra step to load it beyond the usual <code>(require "asdf")</code>:
|
|
ASDF 3 will automatically look whether an updated version of itself is available
|
|
amongst the regularly configured systems, before it compiles anything else.
|
|
</p>
|
|
<p>If your implementation fails to provide ASDF 3 or later,
|
|
see <a href="Replacing-your-implementation_0027s-ASDF.html">Replacing your implementation’s ASDF</a>.
