Hi John, The error you encountered is in compiling the netCDF C++ interface. This may be caused by a problem with your xlC installation. One easy way to get around this is to specify omitting the C++ interface from the build. If you just use the C or Fortran interfaces or other scripting interfaces based on them, you don't really need the C++ interface. To specify you don't want the C++ interface, just set the environment variable CXX to the empty string "" before running the configure script (with a new source tree or after running "make clean"). Otherwise, if you intend to develop using the C++ interface or have other applications that use it, I think you'll have to update xlC or its runtime libraries to handle standard C++ programs. --Russ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: UUG-739716 Department: Support netCDF Priority: Normal Status: Closed
