grid_rotate Make Error

[dashline]

when I compile the grid_rotate, I get the error as followed:

[tianxj@ln1%tianhe grid_rotate]$ make

I think it's the problem of FFLAGS = -m64 -O2 -ffree-line-length-none -ffree-form -Wall, but I don't konw how to configure.

The Makefile is set up with Fortran compiler flags suitable for the GNU Fortran compiler (gfortran). If you're using the Intel fortran compiler (ifort), setting

FFLAGS = -O2 -free

in the Makefile should work.

The error message

grid_rotate.f90(102): error #6632: Keyword arguments are invalid without an explicit interface.   [EXITSTAT]
      call execute_command_line(copyCmd, exitstat=copyStat)
-----------------------------------------^

suggests that the version of ifort that you have doesn't support some parts of the Fortran 2008 standard (which provides for the 'execute_command_line' call). Which version of ifort do you have (you can check with 'ifort --version')?

 

[dashline]

The version of the compiler I'm using now is as follow:

[tianxj@ln1%tianhe grid_rotate]$ ifort --version
ifort (IFORT) 13.0.0 20120731
Copyright (C) 1985-2012 Intel Corporation.  All rights reserved.

And I try the Intel Compiler v18, it works. Is it the compatibilty problem of Intel Compiler v13?
My usual environment is Intel Compiler v13. Do I need to change the environment to Intel v18 once I want to use the grid_rotate compiled with Intel v18?
Thanks!

This does seem like a compatibility problem with the Intel 13 compilers (in the sense that they apparently don't support the 'execute_command_line' call that is part of the Fortran 2008 standard). If you have the Intel 18 compilers available, you could use those when compiling the grid_rotate program, but it might be worth considering using the Intel 18 compilers for everything -- grid_rotate, init_atmosphere_model, atmosphere_model, etc.
