<title>Installation of <application>Tcl</application></title>

<note><para>This package is also installed in <acronym>LFS</acronym> during 
the bootstrap phase. The significant difference between the two installations 
(other than installing to <filename class="directory">/usr</filename>) is 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><command>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</command></userinput></screen>

<para>Now, as the root user:</para>

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

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

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

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