[netCDF #XZZ-356273]: C compiler error in NetCDF 4 installation

Hello Eldon,

Two things leap out at me from what you've provided, and the config.log; thank 
you for sending this, incidentally, it's a great help!

First,

* LIBS=-l/opt/CDO/libs4cdo-0.0.10/hdf5-1.8.6/hdf5/

This would normally be LIBS="-lhdf5"; however, this is unnecessary; the 
configure script will look for libhdf5 automatically and link against it when 
found.  Your definition of LDFLAGS should be changed to include 
"/opt/CDO/libs4cdo-0.0.10/hdf5-1.8.6/hdf5".

Second, netcdf-c requires hdf5 version 1.8.9 or higher; you will want to 
upgrade your hdf5 install.

Third, the line 

* LD_LIBRARY_PATH=/opt/CDO/libs4cdo-0.0.10/netcdf-4.3.3/lib?

Has a stray '?' at the end; if this exists in the definition of 
LD_LIBRARY_PATH, you will want to remove it. Likewise, you will want to modify 
LD_LIBRARY_PATH to include the location containing libhdf5.  

I hope this helps,
