I have tried running the SMOKE test case for version 4.5 on Ubuntu. I try running the scripts in tcsh, but when I enter any of the scripts to run them after changing the directory to $SCRIPTS/run I get an error. I tried putting “smk_area_nctox.csh” put it returns with “command not found”. I also tried “./smk_area_nctox.csh” which did allow the scripts to run but after invoking all the scripts and following the rest of the instructions for the test case it comes back with errors. Any help would be greatly appreciated.
