<div>=========================</div><div><br></div><div>I had tried very hard to get the problem solved but all in vain, even following the suggestions as mentioned in the posts <a href="http://zeus.theochem.tuwien.ac.at/pipermail/wien/2011-December/015856.html">http://zeus.theochem.tuwien.ac.at/pipermail/wien/2011-December/015856.html</a>, <a href="http://zeus.theochem.tuwien.ac.at/pipermail/wien/2010-October/013900.html">http://zeus.theochem.tuwien.ac.at/pipermail/wien/2010-October/013900.html</a></div>
<div><br></div><div>I have tried to install various versions of fftw (fftw-2.1.5, fftw-3-3.2, even intel version of fftw were tried), compiling them using different compilers (mpif90 of mpich2, mpiifort), but the same problem persists, be I use fftw or fftw2 (I also took care of -DFFTW3 and -DFFTW2 accordingly). I can't figure out what's exactly the source of the problem. Your suggestion will be much appreciated.</div>
