Hi Daniel,

I can't duplicate the problem here, because we don't have that version
of g++ on a Solaris 2.4 platform, but I did try building netCDF 3.4
using g++ version 2.8.1 and gcc 2.8.1 on a Solaris 2.6 platform, and
everything seemed to work fine, with no warnings or errors:

   ...
    Making `all' in directory /scratch/russ/builds/sunos_5.6-sparc-3.4/src/cxx

    g++ -c -O -I../libsrc  -DNDEBUG netcdf.cc
    g++ -c -O -I../libsrc  -DNDEBUG ncvalues.cc
    ar cru libnetcdf_c++.a netcdf.o ncvalues.o
    ranlib libnetcdf_c++.a
    g++ -c -O -I../libsrc  -DNDEBUG nctst.cc
    g++ -o nctst -I../libsrc  -DNDEBUG -O  nctst.o libnetcdf_c++.a -L../libsrc 
-lnetcdf 
   ...
    Making `test' in directory /scratch/russ/builds/sunos_5.6-sparc-3.4/src/cxx

    ar cru libnetcdf_c++.a netcdf.o ncvalues.o
    ranlib libnetcdf_c++.a
    ./nctst > test.out
    *** C++ test successful ***

The error you got
> ld: fatal: library -lstdc++: not found

would seem to indicate that your g++ compiler is not looking in the
right place for libstdc++.so.2.7.0.  You might want to reinstall or
upgrade your g++/gcc compilers.

Alternatively, if you aren't planning to use the C++ interface, you
could just specify CXX="" before running the configure script (after
removing the config.cache file and running "make clean").  This would
build the C and Fortran libraries and utilities, which are all that
are needed for many uses of netCDF.
