Error: Deferred-length character component 'long_name' at (1) is not yet supported

Hi,

I am getting error while compiling GOTM. I thought that it would be related to the version, but in the documentation says that gfortran was tested for versions above 4.7.

Versions:

gcc (GCC) 4.8.1 GNU Fortran (GCC) 4.8.1 netCDF 4.3.0

cmake ../code/ -DGOTM_USE_FABM=off

Hi Iury

Thanks for reporting this. We have experienced issues with gfortran before where a later version did not support previous supported features. I don't know if that is the case here.

Anyway gcc 4.8.1 is from May 31, 2013 so a software update might be appropriate.

Gfortran versions below 4.9 will definitely not work with the latest code, as they do not have complete support for allocatable character variables used extensively in GOTM's yaml/setting manager. 4.9 and up could work in theory, but I believe both 4.9 and 5.0 currently have problems with the GOTM code nevertheless. We test with 6 and up:

NB FABM does work with 4.8 and up; it's the GOTM code that requires a later gfortran version.

I tested with gfortran 8.1.0 and it worked.
