We have a problem here. Ward says he duplicated the problem, but using the current github version, I cannot duplicate the problem. Could one or both of you do the following. 1. edit run_pnetcdf_test.sh and insert the command 'set -x' immediately after the '#!/bin/sh' line. 2. Enter the nc_test directory and execute make check 3. report back the complete output. =Dennis Heimbigner Unidata Ticket Details =================== Ticket ID: MRB-844393 Department: Support netCDF Priority: Normal Status: Closed
