Gus- I cannot duplicate this error. So, let try some experiments. 1. Send me the output from "make all" to see if -I../libsrc is being used 2. try changing the #include <netcdf.h> to #include "netcdf.h" and see if that has any effect. 3. copy libsrc/netcdf.h into ncgen3/netcdf.h and rebuild and see if that has an effect. =Dennis Heimbigner Unidata Ticket Details =================== Ticket ID: PZJ-517673 Department: Support netCDF Priority: Normal Status: Open
