    <title>Installation of Ghostscript</title>

    <note>
      <para>The <application>Ghostscript</application> build system is not
      user-friendly. In order to use system copies of various graphics
      libraries, you must do it using unconventional methods.</para>

      <para>First, if you wish to use the system-installed version of
      <application>JasPer</application>, remove the local copy from the
      source tree and apply a patch:</para>

<screen><userinput>rm -rf jasper &amp;&amp;
patch -Np1 -i ../ghostscript-&gs-version;-system_jasper-1.patch</userinput></screen>

      <para>Next, if you wish to use the system-installed copies of
      <application>libjpeg</application> and <application>libpng</application>,
      remove the local copies from the source tree:</para>

<screen><userinput>rm -rf jpeg &amp;&amp;
rm -rf libpng</userinput></screen>

      <para>If you wish to use the system-installed copy of
      <application>libtiff</application>, add the parameter
      <option>--with-system-libtiff</option> to the <command>./configure</command>
      command shown below. Also remove the
      <filename class='directory'>tiff</filename> directory from the source tree
      to prevent the <application>Ghostscript</application> build from using any
      of its local copy.</para>

      <para>Unfortunately, <application>Ghostscript</application> will use local
      copies of <application>Expat</application> and
      <application>Zlib</application> from the source tree. There doesn't
      appear to be an easy way to use system-installed copies of these libraries
      without doing some hacking of the sources.</para>
    </note>

    <para>Install <application>GPL Ghostscript</application> by running the
    following commands:</para>

<screen><userinput>./configure --prefix=/usr --enable-dynamic &amp;&amp;
make</userinput></screen>

    <para>This package does not come with a test suite. However, you may test
    the operation of the newly built <command>gs</command> program by
    issuing the following command (issue from an X Windows terminal):</para>

    <screen><userinput>bin/gs -Ilib -dBATCH examples/tiger.eps</userinput></screen>

    <para>Now, as the <systemitem class="username">root</systemitem> user:</para>

<screen role="root"><userinput>make install docdir=/usr/share/doc/ghostscript-&gs-version; &amp;&amp;

for INSTFILE in `ls doc`
do
  if [ ! -f          /usr/share/doc/ghostscript-&gs-version;/$INSTFILE ]; then
    install -v -m644 doc/$INSTFILE \
                     /usr/share/doc/ghostscript-&gs-version;
  fi
done &amp;&amp;

install -v -m755 -d /usr/share/doc/ghostscript-&gs-version;/figures &amp;&amp;
install -v -m644    doc/figures/* \
                    /usr/share/doc/ghostscript-&gs-version;/figures</userinput></screen>

    <para>To install the shared library
    <filename class='libraryfile'>libgs.so</filename>, run the
    following additional command as an unprivileged user:</para>

<screen><userinput>make so</userinput></screen>

    <para>And again as the <systemitem class="username">root</systemitem>
    user:</para>

<screen role="root"><userinput>make soinstall docdir=/usr/share/doc/ghostscript-&gs-version; &amp;&amp;
install -v -m644 base/*.h /usr/include/ghostscript &amp;&amp;
ln -v -s ghostscript /usr/include/ps</userinput></screen>

    <note>
      <para>The shared library depends on <xref linkend="gtk2"/>. It is
      only used in external programs like <xref linkend="gsview"/> and
      <xref linkend="imagemagick"/>.</para>
    </note>

    <para>To finish the installation, unpack all fonts you've downloaded to
    <filename class="directory">/usr/share/ghostscript</filename> and ensure
    the ownerships of the files are
    <systemitem class="username">root</systemitem>:<systemitem
    class="groupname">root</systemitem>. Substitute
    <replaceable>&lt;font-tarball&gt;</replaceable> appropriately in
    the command below for the fonts you wish to install:</para>

<screen role="root"><userinput>tar -xvf ../<replaceable>&lt;font-tarball&gt;</replaceable> \
    -C /usr/share/ghostscript --no-same-user</userinput></screen>

    <para><command>install ...</command>: Some packages
