Hi,

> Hi, I spend long time to install NetCDF for C++ because I'm not used to

We have two versions of the netCDF-C++ library, an old one for netCDF-3
and a newer version for netCDF-4.  You should use the most recent version,
if possible, netCDF-cxx4 4.2.1.  If you are already using that and built the
library from it, did you run "make check" to run tests on the library, including
compiling and running all the examples, such as simple_xy_wr?

When I run "make check", the last part of the output is:

  PASS: simple_xy_wr
  PASS: sfc_pres_temp_wr
  PASS: pres_temp_4D_wr
  PASS: pres_temp_4D_rd
  PASS: simple_xy_rd
  PASS: sfc_pres_temp_rd
  PASS: simple_xy_wr_formats
  ============================================================================
  Testsuite summary for netCDF-cxx4 4.2.1
  ============================================================================
  # TOTAL: 7
  # PASS:  7
  # SKIP:  0
  # XFAIL: 0
  # FAIL:  0
  # XPASS: 0
  # ERROR: 0
  ============================================================================
  make[1]: Nothing to be done for `check-am'.

If your versions of the test and the library are not the same,
for example you have installed the old netCDF-3 library but
are trying to run the netCDF-4 test, that may be the cause of
the problem. 

The API's of the two versions, netcdf-cxx and netcdf-cxx4 are
similar, but not the same. The netCDF-4 library makes use of
Exceptions and Namespaces, but the old netCDF-3 version does 
not.

If that's not the problem, then please send more details, for example
the config.log file that was generated when you ran the configure 
script to build the library from source.

If you have matching versions of the test examples and library, take
a look at the output from "make check" to see if you are compiling and
linking correctly.
