[GEMPAK #XLB-742768]: Help needed in installing netcdf4

Hello Shucai,

For what purpose are you building netCDF from the GEMPAK extlibs packages?  I 
see that you are manually running configure in order to set the prefix 
directory, and it appears that you are building the GEMPAK netCDF package with 
netcdf4 enabled (compare with the GEMPAK netCDF Makefile which config's the 
package without netcdf4 support (which is not needed in GEMPAK)):

lnetcdf: INSTALLDIR
        -@cd netcdf; \
        pwd; \
        touch macros.make; \
        $(MAKE) distclean ; \
        ./configure --disable-dap --disable-netcdf-4 '--prefix=$(OS_ROOT)'; \
        $(MAKE) all install


So first understand that because you do not include the --disable-netcdf-4 
flag, the netCDF build will attempt to find hdf5 libraries.

Then understand that on your system, the hdf5 libraries that are found are from 
AWIPS II:

libtool: link: gcc -I/usr1/sguan/gempak/workspace/nawips/gempak/include 
...
-L/usr/X11R6/lib64 ../liblib/.libs/libnetcdf.so 
/awips2/tools/lib/libhdf5_hl.so /awips2/tools/lib/libhdf5.so -ldl -lm 
-lz -Wl,-rpath 
-Wl,/usr1/sguan/gempak/workspace/nawips/os/linux2.6.32_x86_64/lib 
-Wl,-rpath -Wl,/awips2/tools/lib
../liblib/.libs/libnetcdf.so: undefined reference to 
`H5P_CLS_DATASET_ACCESS_ID_g'


Notice /awips2/tools/lib/libhdf5.so and /awips2/tools/lib/libhdf5_hl.so.  It is 
this AWIPS II version of libhdf5 that has undefined references.
