Hi Klaus,

> But as soon as I start to write data (via ...putVar(...)) to the file,

Yes, thanks for the error report. I was able to duplicate the problem,
and now there's a fix on GitHub:
https://github.com/Unidata/netcdf-cxx4
as well as a test in the examples/simple_xy_wr_formats.cpp that verifies
that files of all formats can now be created. This fix will be in the
next release, along with a lot of other fixes recently contributed by
another generous developer. If you want to try the latest version, you
can clone the current GitHub release, run "autoreconf -if" in the top-level
directory to generate a "configure" script, and then build it in the usual
way.
> P.S. Merry Christmas and a Happy New Year!
Thanks, same to you and yours ...
