Hi Wanli,

Actually you should expect error messages in "config.log" and these
don't necessarily indicate an installation problem, as explained in
the INSTALL.html instructions:

  The configure script will also create the file "config.log", which
  will contain error messages from the utilities that the configure
  script uses in examining the attributes of your system. Because such
  an examination can result in errors, it is expected that
  "config.log" will contain error messages. Therefore, such messages
  do not necessarily indicate a problem (a better indicator would be
  failure of the subsequent "make"). One exception, however, is an
  error message in "config.log" that indicates that a compiler could
  not be started. This indicates a severe problem in your compilation
  environment -- one that you must fix.
  
So if the only errors you see in "config.log" have to do with not
being able to compile the C++ interface, then that just means it won't
build the C++ interface, but can still build the C and Fortran
interfaces.  If you don't need the C++ interface, that shouldn't be a
problem.  If you need the C++ interface, you might want to try the
current beta release of netCDF 3.5.1, which is closer to the C++
standard:

I doubt if that is the problem.  I was able to build the C, Fortran,
and C++ interfaces with:

    CC=/usr/bin/cc
    CXX=/usr/bin/c++
    CPPFLAGS=-Df2cFortran
    FC=/usr/bin/g77
    FFLAGS=-w 

on Mac OS X 10.1.3.  If you still have trouble, let me know, and maybe
I can make the binaries available.  Another possibility for getting
the netCDF libraries in binary form is to use the "fink" utility, as
described in this netCDF support reply:
