[QE-users] Compiling qe git version with parallel_studio_xe/2020.0.088 will still invoke mpif90.

[Hongyi Zhao]

Hi,

See my following steps on compiling the latest qe git verson with
parallel_studio_xe/2020.0.088:

$ module load parallel_studio_xe/2020.0.088
$ ./configure --with-scalapack=intel
checking build system type... x86_64-pc-linux-gnu
checking ARCH... x86_64
checking setting AR... ... ar
checking setting ARFLAGS... ... ruv
checking for gfortran... no
checking for g95... no
checking for xlf95... no
checking for f95... no
checking for fort... no
checking for ifort... ifort
checking whether the Fortran compiler works... yes
checking for Fortran compiler default output file name... a.out
checking for suffix of executables...
checking whether we are cross compiling... no
checking for suffix of object files... o
checking whether we are using the GNU Fortran compiler... no
checking whether ifort accepts -g... yes
checking for mpif90... mpif90
checking whether we are using the GNU Fortran compiler... no
checking whether mpif90 accepts -g... no
checking version of mpif90... unknown, assuming gfortran
checking for Fortran flag to compile .f90 files... unknown
configure: error: Fortran could not compile .f90 files

Then I try the following command for inspecting the problem:

$ mpif90 --help
/opt/intel/compilers_and_libraries_2020.0.166/linux/mpi/intel64/bin/mpif90:
1: gfortran: not found
/opt/intel/compilers_and_libraries_2020.0.166/linux/mpi/intel64/bin/mpif90:
1: eval: gfortran: not found

It complains gfortran cann't be found. But the module file I used
above has already set the environments for using intel tool chain.

Any hints for this problem?

Regards.
