I'm super new to this code, and really the mac terminal in general, so I'm going through the user's guide step by step. I'm at section 2.2, where I set up the Sedov problem with this command in the FLASH4.8 dir:</div><div>./setup Sedov -auto -site=sam</div><div>Where site=sam because I'm not at any institution so I personalized a makefile for my system. When i run:</div><div>cd object</div><div>make</div><div>It does the compilation for around 30 seconds, and then out of nowhere it throws this:</div><div><p style="margin: 0px 0px 12px; font-style: normal; font-variant-caps: normal; font-width: normal; font-size: 19px; line-height: normal; font-family: "Times New Roman"; font-size-adjust: none; font-kerning: auto; font-variant-alternates: normal; font-variant-ligatures: normal; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-position: normal; font-variant-emoji: normal; font-feature-settings: normal; font-optical-sizing: auto; font-variation-settings: normal; -webkit-text-stroke-width: 0px; -webkit-text-stroke-color: rgb(0, 0, 0);"><span style="font-kerning: none;">f951: Fatal Error: Reading module 'iso_c_binding.mod' at line 1 column 1: Unexpected EOF</span></p>

Then I made a test file that calls iso_c_binding.mod to check for its existence in the FLASH4.8 dir, which did end up working, so I knew it was somewhere. Then I searched for it in Finder, and I realized its a blank file that gets created every time I compile, inside /FLASH4.8/object. So apparently the error arises when it tries to interpret literally nothing. How do I fix this? Please ask if you need more info.</span></div><div><span style="font-kerning: none;"><br></span></div><div><span style="font-kerning: none;">Thank you!</span></div><div><span style="font-kerning: none;">- Sam</span></div></body></html>
