I'm afraid I don't understand this, unless it's a bug in the Unicos 7.0
linker or libraries.  cdftest.c has the statement

        #include <errno.h>

You could try manually executing the line

        cc -O cdftest.o libnetcdf.a -o cdftest -lc

just to make sure it loads from libc.  Another possible thing to try is
using "bld" instead of "ar" to make the library archives, since the Cray
SEGLDR(1) document apparently recommends that.  Finally, you might ask our
mutual friend Dick valent (address@hidden) about how he built it,
since he reports having successfully built and installed netcdf 2.3.2 on a
CRAY YMP in January of this year.  I don't know whether he was using Unicos
7.0 at the time, though.

If this doesn't help, I'll try logging into shavano to see whether they are
running 7.0 and try to track down the problem.  I need an excuse to log in
at least once a year anyway :-).

Say hello to Barb!  (If that's not inappropriate.)
