goto some temporal directory, where hogehoge.tgz (downloaded compiler tarball) is

$tar -zxvf hogehoge.tgz

then, goto directry

$sudo bash; umask
$./install.sh
(GUI instalation makes buggy compiler, maybe because of unsupported OS)

In my installation...

compiler has no problem, but intel MPI does not.

to fix, obtain correct hostname

$hostname
linux-nwxn(in my case)

fix file /etc/hosts as follows
127.0.0.1 localhost → 127.0.0.1 linux-nwxn
(so maybe -localhost option will work, but I did not checked)
it works on 2017-2018. not work on 2019, 2020, for now.

to use intel compiler
$. /opt/intel/parallel_studio_xe_XXXX.X.XXX/psxevars.sh

QE

$export FFT_LIBS="-L$MKLROOT/include/fftw -mkl"
$./configure --enable-parallel --enable-openmp MPIF90=mpiifort CC=mpiicc F90=mpiifort F77=mpiifort --with-scalapack=intel --enable-shared
note that v6.5 is not compilable (@pwi2xsf.f90), while v.6.4 or earlier is OK.
