<h1>Getting Amaya from the CVS Repository</h1>
<div class="intro">
<a href="http://www.cyclic.com/cvs/info.html">CVS</a> allows
<strong>YOU</strong> to follow the development of <a
href="http://www.w3.org/Amaya/">Amaya</a> closely and to contribute with
patches and new features.

<h2><a name="Requiremen">Requirements</a></h2>
<dl>
<dt>Disk space</dt>
<dd>Just checking out requires 8 M for libwww and 38M for Amaya. Building
will easily double the size, so it's better to have 100M available.</dd>
<dt><a href="http://www.cyclic.com/cyclic-pages/howget.html">CVS</a>
(version 1.10 or later)</dt>
<dd>The concurrent version system</dd>

<dd>No need to introduce this fun, lego-like, and poetic scripting
language</dd>
</dl>
<p>On Unix you <strong>MUST</strong> have the following GNU tools installed in
order to continue. Check that you have the following programs with the correct
version number:</p>
<dl>
<dt><a href="http://www.gnu.org/order/ftp.html"><strong>gcc</strong></a> and
<a href="http://www.gnu.org/order/ftp.html"><strong>GNU
make</strong></a></dt>
<dd>Automake relies on features provided by gcc and GNU make that don't
come with other compilers and makes. When compiling directly from CVS
you MUST use these gcc and gmake.</dd>
<dt><strong><a href="http://sourceware.cygnus.com/automake/">GNU
automake</a> (version 1.4 or later)</strong></dt>
<dd>Automake is a tool for automatically generating

<dd>A tool for automatically handling generation of shared libraries. If

<h2><a name="Releases1">Amaya Releases</a></h2>
<p>CVS allows you to use the very latest version of Amaya - as soon as a fix
or a new feature is commited to the CVS repository then you can update your
working version and you will have it right away.</p>
<p>The purpose of "releases" is to say that now we believe that the code is
stable with a well defined set of features. Until now, we have been giving out
distribution files every time we announced a release. This will not change,
but you can <a href="http://dev.w3.org/cgi-bin/cvsweb/">use the CVS
repository</a> in exactly the same way - often with much less overhead than
dealing with a distribution package.</p>
<p>Starting from release 2.1, every release is marked in the CVS repository
using tags, so that it is possible to retrieve a complete release using the
CVS <code>-r </code>option (note that <code>-r</code> is "sticky"). Check out
the online <a href="http://dev.w3.org/cgi-bin/cvsweb/">CVS log walker</a> for
the current set of release tags.</p>
<h2><a name="Anonymous">Anonymous CVS Checkout</a></h2>
<p>To be able to compile Amaya, you will need to check out not only Amaya, but
also <a href="http://www.w3.org/Library/">libwww</a>, from the W3C<a
href="http://dev.w3.org/"> CVS server</a>.</p>
<p>Anonymous checkout is read-only access which allows you to get the latest
edits and to provide patches to be integrated into the code base. The
instructions should work for both <a
href="http://www.cyclic.com/cvs/unix.html">Unix</a> and <a
href="http://www.cyclic.com/cvs/windows.html">Windows</a>. A couple of
notes:</p>
<ul>
<li><a
href="http://lists.w3.org/Archives/Public/www-lib/1999AprJun/0169.html">Win95/98
doesn't have the notion of a home directory so you may have to set it
yourself</a> or define it in <code>Admin/Preferences/WinCVS</code> in <a
href="http://www.wincvs.org/">WinCVS</a></li>
<li>Make sure you are running at least CVS 1.10 or later.</li>
</ul>
<p>Start by login as follows:</p>
<pre>% <strong>cvs -d :pserver:anonymous@dev.w3.org:/sources/public login</strong></pre>
<p>after which you type "<strong>anonymous</strong>" as password.</p>
<h3><a name="latest">Checkout the Latest Version</a></h3>
<p>To get the <em>latest</em> version from the CVS repository, run this
command:</p>
<pre>% <strong>cvs -d :pserver:anonymous@dev.w3.org:/sources/public -z3 checkout Amaya</strong></pre>
<p>libwww is an evolving piece of code. We use the <code>Amaya</code> tag to
identify the current version being used by the Amaya team. To download this
version, run this command:</p>
<pre>% <strong>cvs -d :pserver:anonymous@dev.w3.org:/sources/public -z3 checkout -rAmaya libwww</strong></pre>
<p>If you want to try the bleeding edge libwww, just remove the Amaya tag as
follows:</p>
<pre>% <strong>cvs -d :pserver:anonymous@dev.w3.org:/sources/public -z3 checkout libwww</strong></pre>
<p>After which you will get all the code coming at you. Now you are ready to
<a href="#Boot">getting boot strapped</a>.</p>
<h3><a name="revision">Checkout a Specific Revision</a></h3>
<p>If you want to get a <a href="#Releases">specific release</a> using CVS
tags then you can do this by using the the CVS "<tt>-r</tt>" option, for
example</p>
<pre>% <strong>cvs -d :pserver:anonymous@dev.w3.org:/sources/public -z3 -r Release-2-1 checkout Amaya</strong></pre>
<p>Check the <a href="http://dev.w3.org/cgi-bin/cvsweb/">CVS log walker</a>
for the current set of release tags. If you at some point want to revert to
the latest untagged version then you should use the following command:</p>
<pre>% <strong>cd Amaya</strong>
% <strong>cvs -z3 update -A</strong></pre>
<h2><a name="update">How to Get the Latest Updates</a></h2>
<p>The big advantage of using CVS is that you easily can keep your version of
the code base up to date with the latest edits and changes committed to
CVS.</p>
<p>Once you have <a href="#latest">checked out the amaya and libwww CVS
trees</a> (<a href="#revision">not a specific revision</a>), you can get any
updates committed to the tree by using the <a
href="http://www.loria.fr/~molli/cvs/doc/cvs_16.html#SEC148">cvs update
command</a> like this</p>
<pre>% <strong>cd libwww</strong>
% <strong>cvs -z3 update -d</strong>
% <strong>cd ../Amaya
% <strong>cvs -z3 update -d</strong>
% cd ..</strong></pre>
<p>It is important that you use the "<tt>-d</tt>" flag so that you get new
directories as well as updated files. Now you <strong>MUST</strong> <a
href="#Easy">repeat the compilation bootstrapping</a> procedure.</p>
<h2><a name="Boot">Getting libwww Bootstrapped</a></h2>
<p>When compiling directly from the CVS repository there are a few steps you
have to go through which are already done if compiling from a distribution
package. Follow these three steps:</p>
<ol>
<li><a href="#Easy">Generate include files</a></li>
<li><a href="#More">Unix only: generate make files</a></li>
<li><a href="#Configure">Configure and compile libwww</a></li>
</ol>
<h3><a name="Easy">1. Generate Include Files (Windows & Unix)</a></h3>
<p>On <em>both</em> Windows and Unix you can generate the <tt>*.h</tt> files
and the <tt>*.def</tt> files by running a <a
href="http://www.perl.org/">Perl</a> script provided by <a
href="http://www.w3.org/People/Eric/">Eric Prud'hommeaux</a>. Never mind that
it gives a few warnings when it runs - they are all OK. It requires that you
have a recent version of <a href="http://www.perl.org/">Perl</a> on your
machine. Run the script like this (note the explicit use of the perl
interpreter):</p>
<pre>% <strong>cd libwww</strong>
% <strong>perl config/winConfigure.pl</strong></pre>
<p>Windows people are now done and can jump directly to the instructions for
<a href="SourceDist.html#Installation">how to compile Amaya</a>. On Unix, you
need two additional steps.</p>
<h3><a name="More">2. Generate Makefile (Unix only)</a></h3>
<p>Now <a name="Using11">generate</a> the make files as follows - don't worry
about the <a
href="http://subzero.campus.luth.se/FreeDocs/autoconf-2.12/autoconf_44.html#IDX36">warnings
produced by autoconf</a>:</p>
<pre>% <strong>aclocal; autoheader; automake; autoconf</strong></pre>
<p>Now you <strong>MUST</strong> run the configure script as described in the
next section on <a href="#Compiling">installation instructions</a>. If for
some reason <em>you have trouble</em> running the configure script then try
and run this command instead</p>
<pre>% <strong>make distclean; aclocal; autoheader; automake; </strong><strong>autoconf</strong></pre>
<h3 id="Configure">3. Configure and compile libwww</h3>
<p>It'l be done automatically when you'll <a
href="SourceDist#Installation">compile Amaya</a>.</p>
<h2><a name="Compiling">Configuring and Compiling Amaya</a></h2>
<p>Remember to <a
href="mailto:www-amaya-request@w3.org?subject=subscribe">subscribe to the
<www-amaya@w3.org></a> mailing list (<a

information of new features as well as discussions of problems and ideas.</p>
<p>Congratulations - you are now ready to <a
