<p><strong>Additional info:</strong></p>
<ul>
<li>
Custom site <code>MyLinux</code> created from <code>Prototypes/Linux</code>.
</li>
<li>
<code>flashPar.py</code> exists in <code>source/Simulation/SimulationMain/AlfvenAntenna</code>.
</li>
<li>
Tried <code>make -j4</code> in <code>object/</code>, but no targets are found.
</li>
<li>
Python 3.10 and WSL Ubuntu environment.
</li>
</ul>
<p><strong>Questions: I want to know-</strong></p>
<ol>
<li>
Is it normal for <code>setup.py</code> to report <code>SUCCESS</code> but not generate a Makefile in <code>object/</code>?
</li>
<li>
Are there environment variables or additional steps required to generate the Makefile and compile <code>flash4</code>?
</li>
<li>
Could this be related to WSL, Python 3.10, or missing libraries?
</li>
</ol>
<p>Any guidance would be greatly appreciated.</p><p>Thank you.</p>
<p>Best regards,<br>
