Cannot set F90 flag in configure when gfortran is present
This bug is with the develop branch of Quantum Espresso. I am attaching the config.log and make.inc files.
You will need the Intel 2018 Parallel Studio (compilers + MKL) installed and the environment variable set-up. A gfortran
compiler must be installed and in the path so configure can find it.
The bug is that this command
./configure MPIF90=mpif90 F77=ifort F90=ifort CC=icc
will not set the Intel Fortran Compiler for the F90 variable.
It will set the other compiler variables (F77,MPIF90,CC
) correctly but it will choose gfortran
for F90
and set it in make.inc
. This is incorrect behaviour plus it throws off the HDF5 detection which depends on the value of the F90
config.logmake.inc.
