I clearly misunderstood. If the issue is a non-existent file, then my fix will not help that. I do not think we have ever seen a crash due to accessing a non-existent file. Normally that would be a symptom of an operating system problem. So frankly I am baffled as to how to proceed. As to cmake, we have hired a new person to work on that, but you need to remember that HDF has some 4 times as many programmers as does Unidata and they only have 1 library to support. We have some half a dozen projects. We of course will gratefully take large donations to work on specific projects :-) =Dennis Heimbigner Unidata Ticket Details =================== Ticket ID: WLE-423514 Department: Support netCDF Priority: Normal Status: Closed
