[netCDF #XEI-631234]: Failure to compile netcdf 4.1.1 w/ PGI 10.5 (64-bit linux) (corrected with logs attached)

The problem seems to be compiling the test programs for C++ API:
...
> libtool: link:  pgCC --prelink_objects --instantiation_dir
Template.dir   netcd> f.o ncvalues.o
> pgCC-Warning-prelink_objects switch is deprecated
> pgCC-Warning-instantiation_dir switch is deprecated
> /usr/lib64/crt1.o: In function `_start':

> netcdf.o: In function `NcFile::__ct(char const *, NcFile::FileMode,
unsigned lo> ng *, unsigned long, NcFile::FileFormat)':
> /usr/local/netcdf-4.1.1/cxx/./netcdf.cpp:382: undefined reference to

If you really need the C++ API, here's another possibility.

You have set 

> setenv CXX pgCC
> setenv CPP 'pgCC -E'

but the Portland Group site

  http://www.pgroup.com/resources/netcdf/netcdf40_pgi2010.htm

recommends using

  setenv CC pgCC
  setenv CXX pgcpp

The environment variable "CPP" isn't used by the netCDF configure
script, so setting it has no effect as far as I know.
