How to check for different character lengths in array constructor

[Heinzeller__Dom]

Hi everyone,

I am working on a large community code where many developers are using Intel only, others are using gfortran etc. We keep getting these kind of errors when using gfortran, because apparently the Intel compiler does not check for this by default and the developers are not aware of it:

...
attrList=(/"fhzero", "ncld", "nsoil", "imp_physics", "dtp"/), rc=rc)
                           1
Error: Different CHARACTER lengths (6/4) in array constructor at (1)

As far as I understand, this is part of the Fortran language standard and gfortran is correct (unless using deferred-length character arrays or other Fortran 2003+ features?) So, my question: which kind of compiler flag or switch do I have to use to make the Intel compiler exit with an error in this case?

Thanks very much in advance.

Try -e03 or -e08.

-e compiler option is legacy and its use is now deprecated by Intel if I'm not mistaken.

What users should employ now is -warn stderrors

I will also note that you can use:

attrList=(/character(11)::"fhzero", "ncld", "nsoil", "imp_physics", "dtp"/), rc=rc)

This is standard-conforming and does what Intel Fortran does as an extension.
