You are right "fftw3.f" doesn't have to be in FFTXLib folder because QE<br>
doesn't provide it. And I think, you have already downloaded the<br>
fftw-3.3.4 package. Now you can try to compile it, follow these steps one<br>
by one<br>
(1) Go to fftw-3.3.4 folder<br>
(2) Let's say, you want to install the libraries in "/home/vipin/fftw"<br>
using GCC compilers, then run (its a single command)<br>
<br>
./configure --prefix="/home/vipin/fftw" --enable-shared --enable-threads<br>
--enable-openmp F77=gfortran CC=gcc FFLAGS=-O3 CFLAGS=-O3<br>
<br>
(3) If above step finishes with out error then run these two commands<br>
<br>
make all<br>
make install<br>
<br>
(4) If everything goes fine you will have your "fftw3.f" file in<br>
"/home/vipin/fftw/include" folder. You will also have to update the<br>
LD_LIBRARY_PATH. Add the following line into your bashrc (a hidden file in<br>
your home folder, it can be listed using "ls -a" command)<br>
<br>
export LD_LIBRARY_PATH="/home/vipin/fftw":${LD_LIBRARY_PATH}<br>
<br>
And run the following command<br>
<br>
. ~/.bashrc<br>
<br>
(5) Now go to your QE directory and follow the steps outlined in my last<br>
email.<br>
