<div class="moz-cite-prefix">You probably should adjust the settings
in siteconfig.<br>
<br>
./siteconfig<br>
In the menu for example, select P, n, n, 0 (may not work
correctly; refer to my previous mailing list post), ssh, y, enter
your f90 compiler, and the -DFFTW3 can be changed in FPOPT<br>
<br>
If want to change in the Makefile manually (likely overriden if
you use siteconfig), open the Makefile in a text editor:<br>
<br>
vi $WIENROOT/SRC_lapw0/Makefile<br>
<br>
You should see -DFFTW3 in the FPOPT line. There should also be
fftw3 options in RP_LIBS, if it has not been changed from the
default settings.<br>

We are running Wien2k11 version in complete parallel and
presently trying to install Wien2k-12.1 in parallel. While
installing, we have error in SRC_lapw0. i.e.<br>

From the forum we got the information that FFT3 compilers should
be changed in Makefile. Can you please explain ( where I can find
-DFFT3 or -DFFT2 in Makefile for SRC_lapw0) ?????<br>
<br>
Thanks in advance<br>
<br>
With regards<br>
