missing functions from iso_fortran_env

[Alin_M_Elena]

Hi,

I was trying to use the new functions defined in iso_fortran_env, compiler_options and compiler_version.

Unfortunately turns out that intel fortran compilers does not support them. Do I miss anything?

the code is trivial

   program version_options                    
      use iso_fortran_env, only : compiler_version, compiler_options
      implicit none                            
                                               
      write(*,*)"Compiler: ", compiler_version()
      write(*,*)"Options: ", compiler_options()                                                                                    
   end program version_options

Yes, these are still not supported in the current upcoming 17.0 release but Development is actively working on adding these. I don't know whether they will be targeted to an update to 17.0 or a later major version. Any update will be posted in the earlier thread, here.

thank you totally missed the earlier report.

Please can I add that these two features cannot be very difficult for Intel to support, but they are potentially very useful for users. I send out compiled code and source code to colleagues in my research group, and I get comments back on the (very rare) occasions when they think there may be a bug. Being able to see output from these two functions in the program output files makes support so much easier.

please, pretty please...

New and Changed Compiler Features

The Intel® Fortran Compiler now supports all features from the Fortran 2008 standard. Additional Fortran 2008 features added in the Intel® Fortran 18.0 release are noted below. Please refer to the Fortran 2008 Standard (PDF) and the proposed draft Fortran 2015 Standard (PDF) if necessary.

Features from Fortran 2008

• COMPILER_OPTIONS and COMPILER_VERSION in ISO_FORTRAN_ENV
• ..

Actually, these are not straightforward to support due to the way the Intel compiler has handled intrinsic modules to date. A new mechanism needed to be added to allow a module function to be used in a constant expression. As FortranFan notes, this was done for the upcoming 18.0 release - required for full F2008 support.
