[Pw_forum] problem with fftw3

[j brandon keith]

Hi, I used to run quantum espresso all the time, but now when I try to
compile (old or new version), I get an error in fftw3 library...an
example is example01:

This example shows how to use pw.x to calculate the total energy and
the band structure of four simple systems: Si, Al, Cu, Ni.

  executables directory: /home/jbk/espresso-4.3/bin
  pseudo directory:      /home/jbk/espresso-4.3/pseudo
  temporary directory:   /home/jbk/tmp
  checking that needed directories and files exist... done

  running pw.x as: mpirun -np 1 /home/jbk/espresso-4.3/bin/pw.x
  running bands.x as: mpirun -np 1 /home/jbk/espresso-4.3/bin/bands.x

  cleaning /home/jbk/tmp... done
  running the scf calculation for Si...[zen:03240] *** Process
