Dr. Grabowski, I can verify that all the netCDF tests pass on a Solaris platform using Solaris compilers with -m64, if you first build with gcc with CFLAGS including -m64 and then copy the one object file ncdump/dumplib.o from the gcc build tree into the Solaris ncdump/ directory, then run "make check" and "make install". For now, this is the only workaround to the problem. I've added a note on this to the "Known Problems with netCDF 4.0.1" at http://www.unidata.ucar.edu/software/netcdf/docs/known_problems.html Please let me know if you want any changes to that entry, and thanks again for reporting the problem. --Russ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: YYM-734195 Department: Support netCDF Priority: Normal Status: Closed
