[netCDF #JKS-717625]: problem to install NETCDF-4.1.1 with PGI compiler

Omid,

I think the environment variable setting above is a problem.  pgCC is
a C++ compiler, not a C compiler.

You should use

  export CC=pgcc

A C++ compiler will often work as a C compiler on small test programs,
but we haven't tested building the netCDF libraries from source with
just a C++ compiler.  There are some incompatible differences between
C++ and C.  By the way, "pgcpp" is another alias for the same C++
compiler as pgCC, so your setting for CXX is OK.

> export CXX=pgcpp
> export FC=pgf90
> export LD=pgf90

That's a peculiar setting for LD.  It may work, but we don't test with
that, and don't use any setting for LD.

> export CFLAGS="-O2"
> export FFLAGS="-O2 -Msignextend"

We use 

  CFLAGS="-O2 -Msignextend"

to match the FFLAGS setting.

> export CPPFLAGS="-DpgiFortran"
> 
> export OBJECT_MODE=64

If you don't have the HDF5 library installed and just need the classic
netCDF data model, the recomendations above should work.

If you have installed the HDF5 library and want to use the netCDF-4
features, such as compression and chunking, you will also need to
specify where to find the HDF5 library and include files.  In version
4.1.3, this uses the two env variables LDFLAGS and CPPFLAGS, for
example

  export LDFLAGS="-L/usr/local/hdf5-1.8.7/lib 
-L/usr/local/pgi/linux86-64/11.1/lib"
  export CPPFLAGS="-DpgiFortran -I//usr/local/hdf5-1.8.7/include"

You can see the results of our testing with the PGI compilers in
version 4.1.3, including example output from running configure and
make, here, by searching for "PGI" and clicking on the associated
