The following tools are used to process the documentation. Some
might be optional, as noted.
</p><div class="variablelist"><dl class="variablelist"><dt><span class="term"><a class="ulink" href="https://www.oasis-open.org/docbook/" target="_top">DocBook DTD</a></span></dt><dd><p>
This is the definition of DocBook itself. We currently use version
4.5; you cannot use later or earlier versions. You need
the <acronym class="acronym">XML</acronym> variant of the DocBook DTD, not
the <acronym class="acronym">SGML</acronym> variant.
</p></dd><dt><span class="term"><a class="ulink" href="https://github.com/docbook/wiki/wiki/DocBookXslStylesheets" target="_top">DocBook XSL Stylesheets</a></span></dt><dd><p>
These contain the processing instructions for converting the
DocBook sources to other formats, such as
<acronym class="acronym">HTML</acronym>.
</p><p>
The minimum required version is currently 1.77.0, but it is recommended
to use the latest available version for best results.
</p></dd><dt><span class="term"><a class="ulink" href="http://xmlsoft.org/" target="_top">Libxml2</a> for <code class="command">xmllint</code></span></dt><dd><p>
This library and the <code class="command">xmllint</code> tool it contains are
used for processing XML. Many developers will already
have <span class="application">Libxml2</span> installed, because it is also
used when building the PostgreSQL code. Note, however,
that <code class="command">xmllint</code> might need to be installed from a
separate subpackage.
</p></dd><dt><span class="term"><a class="ulink" href="http://xmlsoft.org/XSLT/" target="_top">Libxslt</a> for <code class="command">xsltproc</code></span></dt><dd><p>
<code class="command">xsltproc</code> is an XSLT processor, that is, a program to
convert XML to other formats using XSLT stylesheets.
</p></dd><dt><span class="term"><a class="ulink" href="https://xmlgraphics.apache.org/fop/" target="_top">FOP</a></span></dt><dd><p>
This is a program for converting, among other things, XML to PDF.
It is needed only if you want to build the documentation in PDF format.
</p></dd></dl></div><p>
</p><p>
We have documented experience with several installation methods for
the various tools that are needed to process the documentation.
These will be described below. There might be some other packaged
distributions for these tools. Please report package status to the
documentation mailing list, and we will include that information
here.
</p><div class="sect2" id="id-1.11.11.5.4"><div class="titlepage"><div><div><h3 class="title">J.2.1. Installation on Fedora, RHEL, and Derivatives</h3></div></div></div><p>
To install the required packages, use:
</p><pre class="programlisting">
yum install docbook-dtds docbook-style-xsl libxslt fop
</pre><p>
</p></div><div class="sect2" id="id-1.11.11.5.5"><div class="titlepage"><div><div><h3 class="title">J.2.2. Installation on FreeBSD</h3></div></div></div><p>
To install the required packages with <code class="command">pkg</code>, use:
</p><pre class="programlisting">
pkg install docbook-xml docbook-xsl libxslt fop
</pre><p>
</p><p>
When building the documentation from the <code class="filename">doc</code>
directory you'll need to use <code class="command">gmake</code>, because the
makefile provided is not suitable for FreeBSD's <code class="command">make</code>.
</p></div><div class="sect2" id="id-1.11.11.5.6"><div class="titlepage"><div><div><h3 class="title">J.2.3. Debian Packages</h3></div></div></div><p>
There is a full set of packages of the documentation tools
available for <span class="productname">Debian GNU/Linux</span>.
To install, simply use:
</p><pre class="programlisting">
apt-get install docbook-xml docbook-xsl libxml2-utils xsltproc fop
</pre><p>
</p></div><div class="sect2" id="id-1.11.11.5.7"><div class="titlepage"><div><div><h3 class="title">J.2.4. macOS</h3></div></div></div><p>
If you use MacPorts, the following will get you set up:
</p><pre class="programlisting">
sudo port install docbook-xml docbook-xsl-nons libxslt fop
</pre><p>
If you use Homebrew, use this:
</p><pre class="programlisting">
brew install docbook docbook-xsl libxslt fop
</pre><p>
</p><p>
The Homebrew-supplied programs require the following environment variable
to be set. For Intel based machines, use this:
</p><pre class="programlisting">
export XML_CATALOG_FILES=/usr/local/etc/xml/catalog
</pre><p>
On Apple Silicon based machines, use this:
</p><pre class="programlisting">
export XML_CATALOG_FILES=/opt/homebrew/etc/xml/catalog
</pre><p>
Without it, <code class="command">xsltproc</code> will throw errors like this:
</p><pre class="programlisting">
I/O error : Attempt to load network entity http://www.oasis-open.org/docbook/xml/4.5/docbookx.dtd
postgres.sgml:21: warning: failed to load external entity "http://www.oasis-open.org/docbook/xml/4.5/docbookx.dtd"
...
</pre><p>
</p><p>
While it is possible to use the Apple-provided versions
of <code class="command">xmllint</code> and <code class="command">xsltproc</code>
instead of those from MacPorts or Homebrew, you'll still need
to install the DocBook DTD and stylesheets, and set up a catalog
file that points to them.
</p></div><div class="sect2" id="DOCGUIDE-TOOLSETS-CONFIGURE"><div class="titlepage"><div><div><h3 class="title">J.2.5. Detection by <code class="command">configure</code></h3></div></div></div><p>
Before you can build the documentation you need to run the
<code class="filename">configure</code> script, as you would when building
the <span class="productname">PostgreSQL</span> programs themselves.
Check the output near the end of the run; it should look something
like this:
</p><pre class="screen">
checking for xmllint... xmllint
checking for xsltproc... xsltproc
checking for fop... fop
checking for dbtoepub... dbtoepub
</pre><p>
If <code class="filename">xmllint</code> or <code class="filename">xsltproc</code> is not
found, you will not be able to build any of the documentation.
<code class="filename">fop</code> is only needed to build the documentation in
PDF format.
<code class="filename">dbtoepub</code> is only needed to build the documentation
in EPUB format.
</p><p>
If necessary, you can tell <code class="filename">configure</code> where to find
these programs, for example
</p><pre class="screen">
./configure ... XMLLINT=/opt/local/bin/xmllint ...
</pre><p>
