Compilation error

[Kedar G. Bhide]

I'm using latest version of PENCIL code from GitHub. It works fine on our workstation. When I try to compile it on supercomputing facility it is giving following error. Our workstation works on CentOS 6.3 where as supercomputing facility has CentOS 6.2. Previous version of PENCIL code worked fine on both the systems. I'm using mpif90 compiler.

I've run into something similar, I seem to recall fixing it by changing -std=f95 to something more recent (I think Fortran 08).

My configuration file default.conf is like this. Still it is giving same error.

%section Makefile
        FC = mpif90
        FSTD_90=-std=f2008
        CC = mpicc
%endsection Makefile

[Philippe-A. Bourdin]

Hello,

The error shown here arises from an MPI library that is not compatible with the Fortran standard (F95 or F2003, depending on which modules you use), as the error messages says:

   integer*8 MPI_DISPLACEMENT_CURRENT
            1

Error: Nonstandard type declaration INTEGER*8 at (1) 

Shifting the Fortran standard requirements to something even higher (F2008) can not work in this case. Instead, you should switch OFF the Fortran standard checking, which is simply done by setting:
FSTD=
in your configuration. Please never change the settings of "FSTD_*" because these are not meant to be changed.

Otherwise, it is always a good start to follow exactly the steps given in our "quick start guide" that is linked on our homepage, also if you want to submit a Bug report.

Thanks and best greetings,
Philippe.
