<h2>Install XSM Machine Simulator</h2>
<p>
The compiler's target code needs to be run on a simulator and the installation steps are given below.
</p>
<p>
<h4>Let us install XSM</h4>
<h5> Step 1 : </h5>
<!-- <p> Download XSM Simulator : <a href="files/xsm_expl.tar.gz" class="button"> Version 1 </a> </p> -->
<p> Download XSM Simulator : <a href="files/xsm_expl.tar.gz" class="button"> Version 1 </a> </p>
</p>
<h5> Step 2 :</h5>
<p> Extract this file and navigate into the folder <b>xsm_expl</b> through the terminal.</p>
<p>
Do the following steps:<br>
<ul>
<li id="otis">1. Type "make".
<p>
You may get some warnings and they can be ignored. If you get any <b>fatal error</b>,
then install the following dependencies and try running "make" again : <br>
<b>sudo apt-get install libreadline-dev</b> <br>
<b>sudo apt-get install libc6-dev</b> <br>
<b>sudo dnf install readline-devel # for fedora</b> <br>
If any other dependencies are missing (this depends on your system configuration), you have to install the missing dependencies
and run "make" again.
(Optional) While running "./xsm" after Step 2 if you get this error:<br>
<i>/usr/bin/ld: cannot find -ll
collect2: error: ld returned 1 exit status</i>
Then you need to install:<br>
<b>sudo apt-get install libfl-dev</b> <br>
and edit the <b>Makefile</b> of <b>xsm_dev</b> folder, to proceed
find the line where "-ll" is used as option and update it to "-lfl" to use the "flex" library we installed above.
Now you can run "make" again after navigating into the folder <b>xsm_expl</b> through the terminal.
</p>
<p>If you run into errors pretaining to <b>/usr/include/readline/*</b>, Update <b>xfs-interface/interface.c</b> and include <b>stdio.h</b> before readline headers</p>
<br>
</li>
<li id="otis">2. Type "cd ../xfs-interface/" and type "./init".</li>
<br>
<li id="otis">3.(Optional) Add this line <b>#!/usr/bin/env bash</b> as first line to the <b>xsm</b> file in <b>xsm_expl</b> folder.</li>
This step is for those who don't have <b>bash</b> or <b>sh</b> as their "default shell" and therefore may be using other
customizable shells like <b>zsh</b>, etc as their default shell. You can check your default shell by using <b>echo $SHELL</b> in terminal.
</ul>
</p>
