Re: problem compiling the NCAR graphics ubuntu 10.04 with gcc/gfortran 4.4.3

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:

http://www.earthsystemgrid.org

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:

ncl_ncarg-6.0.0-beta.Linux_Debian_x86_64_gcc432.tar.gz

ncl_ncarg-6.0.0-beta.Linux_Debian_x86_64_gcc445.tar.gz

Or, if you want non-OPeNDAP enabled:

ncl_ncarg-6.0.0-beta.Linux_Debian_x86_64_nodap_gcc432.tar.gz

ncl_ncarg-6.0.0-beta.Linux_Debian_x86_64_nodap_gcc445.tar.gz
