If you believe you've registered, is it possible you are posting from an email address different than the one you registered with? Its best to post to these public forums, not the xxxx_owner forums, because there are more eyes and more expertise looking at the postings.</div><div><br></div><div>As to your particular issue, I am perplexed. The error is emanating out of the gdal library, and its referencing a symbol, error_top, which is defined in the HDF4 library. I do not see the HDF4 libraries referenced anywhere in the logfile you sent, so its hard to tell where the missing dependency is coming from.</div><div><br></div><div>I note that you did a "yum install" on ncl. We do not have control over the yum distributions of NCL. An NCL installation is intended to be cleanly installed in under a single NCAR_ROOT directory, but we've seen some distributions, notably on debian/ubuntu, place parts of the ncl distro in non-standard places, which confounds things and requires setting special environment variables to make things work.
