    <title>Installation of Tcl</title>

    <note>
      <para>This package is also installed in LFS during
      the bootstrap phase. The significant difference between the two installations
      (other than installing to <filename class="directory">/usr</filename>) is that
      the package is installed in such a way that there is no need to keep the build
      directory around after installation.</para>
    </note>

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

<screen><userinput>export VERSION=&tcl-version; &amp;&amp;
export V=`echo $VERSION | cut -d "." -f 1,2` &amp;&amp;
export DIR=$PWD &amp;&amp;
cd unix &amp;&amp;
./configure --prefix=/usr --enable-threads &amp;&amp;
make &amp;&amp;
sed -i "s:${DIR}/unix:/usr/lib:" tclConfig.sh &amp;&amp;
sed -i "s:${DIR}:/usr/include/tcl${V}:" tclConfig.sh &amp;&amp;
sed -i "s,^TCL_LIB_FILE='libtcl${V}..TCL_DBGX..so',\
TCL_LIB_FILE=\"libtcl${V}\$\{TCL_DBGX\}.so\"," tclConfig.sh</userinput></screen>

    <para>To test the results, issue: <command>make test</command>.</para>

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

<screen role="root"><userinput>make install &amp;&amp;
install -v -d /usr/include/tcl${V}/unix &amp;&amp;
install -v -m644 *.h /usr/include/tcl${V}/unix/ &amp;&amp;
install -v -d /usr/include/tcl${V}/generic &amp;&amp;
install -v -c -m644 ../generic/*.h /usr/include/tcl${V}/generic/ &amp;&amp;
rm -v -f /usr/include/tcl${V}/generic/{tcl,tclDecls,tclPlatDecls}.h &amp;&amp;
ln -v -nsf ../../include/tcl${V} /usr/lib/tcl${V}/include &amp;&amp;
ln -v -sf libtcl${V}.so /usr/lib/libtcl.so &amp;&amp;
ln -v -sf tclsh${V} /usr/bin/tclsh</userinput></screen>

    <para>Clean up the unprivileged user's environment using the following
    commands:</para>

<screen><userinput>unset VERSION &amp;&amp;
unset V &amp;&amp;
unset DIR</userinput></screen>

<!--
    <caution>
      <para>If you build the package as an ordinary user and then switch to
      root to install the package, ensure you set the environment variables
      <envar>V</envar> and <envar>VERSION</envar> before running the installation
      commands.</para>

    <title>Command Explanations</title>

    <para><parameter>--enable-threads</parameter>: This switch forces the package
    to build with thread support.</para>

    <para><command>sed -i ...</command>: The <application>Tcl</application>
    package assumes that the source that is used to build
    <application>Tcl</application> is always kept around for compiling packages
    that depend on <application>Tcl</application>. These <command>sed</command>s
    remove the reference to the build directory and replace them by saner system
    wide locations.</para>

    <para><command>install ...</command>: These commands install the internal
    headers into a system-wide location.</para>

    <para><command>ln -v -sf ...</command>: These commands create compatibility
    symbolic links.</para>
