    <title>Installation of Ghostscript</title>

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

      <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>
      </note>

      <para>Begin by patching some vulnerabilities:</para>

<screen><userinput>patch -Np1 -i ../ghostscript-&gs-version;-security_fixes-1.patch
</userinput></screen>

      <para><application>GPL Ghostscript</application> includes (old) copies of
      several libraries. Some of these seem to have been patched to fix known
      vulnerabilities, but others of these copies are less-well maintained.
      To ensure that any future fixes are applied throughout the whole system,
      it is recommended that you build the released versions of these libraries
      and then configure <application>GPL Ghostscript</application> to link to
      them. This configuration has several steps.</para>

      <para>Unless you intend to build <application>GPL Ghostscript</application>
      without support for <literal>JPEG2000</literal> files, apply a patch to
      allow it to build against a current system-installed version of
      <application>JasPer</application>:</para>

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

      <para>Remove the local copies of <application>expat</application>,
      <application>JasPer</application>, <application>lcms</application>,
      <application>libjpeg</application>, <application>libpng</application>,
      <application>libtiff</application>, and <application>zlib</application>:
      </para>

<screen><userinput>rm -rf expat jasper lcms jpeg libpng tiff zlib
</userinput></screen>

    <para>Run the configure command:</para>

<screen><userinput>./configure --prefix=/usr --enable-dynamic --with-drivers=ALL,x11 --with-system-libtiff --disable-compile-inits</userinput></screen>

    <para>To ensure the build is able to use the system versions of
    <application>expat</application>, <application>freetype</application>, and
    <application>lcms</application> it is necessary to make some changes and an
    addition to the <literal>Makefile</literal> before building the package:</para>

<screen><userinput>sed -i  -e 's|SHARE_LCMS=0|SHARE_LCMS=1|' \
        -e 's|LCMSSRCDIR=lcms|LCMSSRCDIR=/usr|' \
        -e 's|=imdi|&amp;\n\n# Use system expat library\n\nSHARE_EXPAT=1|' \
        -e 's|SHARE_FT=0|SHARE_FT=1|' Makefile &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>

<!-- for 9.00 docdir is only referenced by GS_DOCDIR which is itself not referenced
 so the docs still go into /usr/share/ghostscript/9.00/
<screen role="root"><userinput>make install docdir=/usr/share/doc/ghostscript-&gs-version; &amp;&amp;-->
<screen role="root"><userinput>make install &amp;&amp;

  if [ ! -f          /usr/share/ghostscript/&gs-version;/doc/$INSTFILE ]; then
    install -v -m644 doc/$INSTFILE \
                     /usr/share/ghostscript/&gs-version;/doc
                     <!--/usr/share/doc/ghostscript-&gs-version;-->
  fi
done &amp;&amp;

                    <!--/usr/share/doc/ghostscript-&gs-version;/figures-->
ln -sv ../ghostscript/&gs-version;/doc /usr/share/doc/ghostscript-&gs-version;
</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-owner</userinput></screen>

    any <literal>JPEG2000</literal> files, this switch (and removing the

    <para><option>--without-jbig2dec</option>: The <literal>JBIG2</literal>
    decompression code (used for some faxes) can be disabled by using this switch
    and removing the <filename class="directory">jbig2dec/</filename> source.</para>
    <para><command>install ...</command>: Some packages
