Hi Tushar, You didn't mentions your OS so I assume its Ubuntu and you have already installed "libfftw3-dev" package. Now you can try the following, first find out the location of "fftw3.f" and then add it to your IFLAGS in "make.sys" file. For Ubuntu 12.04 LTS this file is located in "/usr/include/". After adding to IFLAGS, it should look like
IFLAGS = -I../include -I/usr/include/ If above doesn't work, then try to copy the file into FFTXlib folder located in your main QE directory and have look at the discussion http://www.mail-archive.com/pw_forum%40pwscf.org/msg27600.html HTH Surender Kumar > Dear all, > > I am a novice to this field of computational studies and i am trying to > install quantum espresso version 5.3.0 in linux so as I run the > configuration file I am getting an error which says unable to find a > fftw3.f file.
