Vasso,

I'm at a loss here, I used your cdl 00.cdl and it converted a avn 1x1
degree grid with no problem. I was using a decoders-2.4.4.tar.Z, linux 7.3
system and the gcc compiler.  You might want to set CC first,

in csh use
% setenv CC gcc
or borne, bash, etc
% CC=gcc;export CC

Make sure to run:

% make distclean
% ./configure

again.


Also when you run gribtonc set a log file, ie

% gribtonc -vl log 00.cdl avn.nc < onedeg

The log file should have errors in it.   You could send me the log file,
that should help. If the file is large, remove the -v flag because
critical errors will still be written to log
