netcdf - added a largefile variant that makes changes to netcdf.h

[johntfosterjr@…]

Created a patch file to make changes to netcdf.h to support exodusii "largefile" datasets. This is needed to create an exodusii port. Added the variant "largefiles" to the Portfile.

netcdf is one of the basic library for science applications. It is better to keep it as it is. Doesn't the proposed changes affect other ports? Does exodusii need the header after installation? If it requires a modified header at the compile time, just make a copy of netcdf.h, edit and use it for build. If exodusii is a framework and it needs the modified header at runtime, you could install the modified header at different location (include/exodusii/netcdf.h) or a different name (netcdf-exodusii.h).

I could add netcdf-largefiles subport. Everything will be installed in ${prefix}/lib/netcdf-largefiles. If you are still going to port exodusii to MacPorts, I will commit the change to add the subport. Otherwise, I'd like you to use the local tree feature for your own purpose.

I close this ticket for now. I am ready to create the subport if you need it for another port.
