You might try the 4.1.2-beta (ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf-4.1.2-beta1.tar.gz) It should fix the first problem (gmake1-out), but I do not know about the second. We unfortunately do not have an AIX platform to test on currently. =Dennis Heimbigner Unidata Ticket Details =================== Ticket ID: QPK-184863 Department: Support netCDF Priority: Normal Status: Open
