Hi Saulo,

We just released NCL V6.0.0-beta, and I think we got rid of most of the gfortran_xxxx undefined issues.

We have LINUX x86_64 binaries that were compiled with gcc 4.3.2 and gcc 4.4.5. You might try one of these and see if the problem goes away.

The 6.0.0-beta version is on the ESG:

Click on "NCL: NCAR Command Language" and then "NCL Version 6.0.0-beta".

Decide whether you want OPeNDAP-enabled or non-OPeNDAP enabled binaries and click on the corresponding link.

The OPeNDAP files of interest are:



Or, if you want non-OPeNDAP enabled:
