Although we don't have access to a CONVEXOS platform, previous experience from other users has indicated that there is a problem with the Convex XDR implementation (specifically in its handling of very small (sub-normal) numbers). Our `configure' script tests the native XDR library to try to decide whether to use it or the generic XDR library we supply with the netCDF distribution. This XDR library test fails on CONVEXOS because of the problem with subnormal numbers, so the installation ties to use the generic XDR library, which has never been modified to work correctly under CONVEXOS. Here's an excerpt of a previous reply from Steve Emmerson (address@hidden) about the problem and possible workarounds: Unfortunately, we don't have the resources here to modify our XDR implementation for CONVEXOS. Since the problem only appears with subnormal, floating-point values, however, I suggest that you simply ignore the problem (unless your applications require proper handling of subnormal floating-point values -- in which case you'll have to modify our XDR implementation or CONVEXOS's). You can ignore the problem by instructing the makefile system to use the system's XDR implementation. This is done by invoking the make program in the following way: % make all CPP_XDR=-I/usr/include/rpc \ LD_XDR= \ XDR_LIBOBJS= \ XDR_INSTALL_DEPS= Note that the last three macros are defined to be the empty string. If you "make test" from the top level directory with the above macro definitions, then you will still get the error. Thus, to test the netCDF package you'll have to invoke the test individually, i.e. % make libsrc/test nctest/test fortran/test ncdump/test ncgen/test CPP_XDR=-I/usr/include/rpc \ LD_XDR= \ XDR_LIBOBJS= \ XDR_INSTALL_DEPS= Then, invoke "make install" with the above macro definitions. Hope this helps. -- Russ Rew UCAR Unidata Program address@hidden P.O. Box 3000 http://www.unidata.ucar.edu/ Boulder, CO 80307-3000
