<div>Hello, vidhya sankar - </div><div><br></div>If the env. var&#39;s are really set and operate correctly, one should look for the problem in the MOPAC library itself. Do you use precompiled libmopac.a or compile it by hand? <div>

<br></div><div>BTW, did you try to exactly follow the procedure described on my website, from the very beginning??</div><div><br></div><div>Best.</div><div><br></div><div>-- </div><div>Dr. Vitaly V. Chaban<br>Department of Chemistry<br>

&gt; ./configure --with-qmmm-mopac --disable-float<br>&gt; it configure successfully<br>&gt; but when i compile by make command i got the following error at the end of my compilation<br>&gt;<br>&gt; libs/libgmxpreprocess_d.a ../mdlib/.libs/libmd_d.a
