<P>
Jacl users should note that a pre-compiled binary release is available,
so building from source is not required. Jacl is built using a
<code>configure</code> script and has been tested on a variety
of UNIX/Linux systems.
</P>

<P>
First, download the Jacl archive file and uncompress it into a
directory. The following assumes that the user has created
a temp directory <code>/tmp/jacl</code>, that the archive
file has been downloaded and saved in this directory, that
Jacl will be installed into <code>/opt/jacl</code>, and
that the JDK install is located in <code>/opt/jdk14</code>.

<blockquote>
<pre>
<code>
cd /tmp/jacl
tar -xzvf jacl1.4.0.tar.gz
mkdir build
cd build
../jacl1.4.0/configure --prefix=/opt/jacl --with-jdk=/opt/jdk14</pre>
</code>
</pre>
</blockquote>
</p>

<p>
After the configure script finishes, run the following commands
to build and install Jacl.

<blockquote>
<pre>
<code>
make
make install
</code>
</pre>
</blockquote>
</p>

<p>
One can also build and run the optional regression
tests with the following command. Be aware that
running the regression tests can take a long time.

<blockquote>
<pre>
<code>
make test
</code>
</pre>
</blockquote>
</p>

<p>
Running <code>make install</code> will install a startup script that
should be used run Jacl. This script is named <code>jaclsh</code>,
it would be installed into <code>/opt/jacl/bin/jaclsh</code> by
the example above.
</p>


<blockquote>
<pre>
<code>
/opt/jacl/bin/jaclsh
% package require java
1.4.0
% exit
</code>
</pre>
</blockquote>
</p>

<H4>TJC Compiler</H4>

<p>
The TJC compiler is included in Jacl 1.4.0 and later releases.
The TJC compiler is used to compile Tcl code into Java bytecode
which is then executed directly in the JVM. Since the TJC compiler
is implemented in Tcl, TJC can be used to compile itself. This
is known as a 2-stage compile and makes the TJC compiler execute
about 10 times faster. For this reason, it is suggested that users build
TJC via a 2-stage compile as follows. Be aware that this process
is very slow, it can take 20 minutes or more on a fast system.
Also note that Jacl must have been built and installed before
the following commands are run.

<blockquote>
<pre>
<code>
make tjc2
make install
</code>
</pre>
</blockquote>
</p>
