[netCDF #LHQ-297925]: 4.1.3-beta1 configure issue

Hi Davide,

> Running the configure script for netcdf4.1.3-beta1 fails (making the
> install on bluefire more challenging than usual)
> The root cause of this problem is that configure "forgets" to use the
> required includes.
> For example, calling
> ./configure --enable-netcdf-4 --with-udunits --with-libcf
> --with-hdf5=/contrib/hdf5-1.8.6_seq --with-zlib=/contrib/zlib/
> --with-szlib=/contrib/szip/ --prefix=/contrib/somewhere
> will produce the following (which fails) in config.log for 4.1.3-beta1
> configure:26283: checking for H5Fflush in -lhdf5
> configure:26308: xlc_r -o conftest  -qarch=auto -qtune=auto -qcache=auto
> -L/contrib/szip/lib -L/contrib/zlib/lib conftest.c -lhdf5  -lz -lm -lm
> -lsz >&5
> whereas it produced the following (which succeeded) in 4.1.2:
> configure:26822: checking for H5Fflush in -lhdf5
> configure:26847: xlc_r -o conftest  -qarch=auto -qtune=auto -qcache=auto
> -I/contrib/zlib//include -I/contrib/hdf5-1.8.6_seq/include
> -I/contrib/szip//include -L/contrib/szip/lib -L/contrib/zlib/lib -L/contri
> b/zlib//lib -L/contrib/hdf5-1.8.6_seq/lib -L/contrib/szip//lib
> conftest.c -lhdf5  -lz -lm -lsz >&5

When 4.1.3-beta1 was announced, the following was included (but not very 
in the netcdfgroup announcement:

  This release also includes a simplification of the netCDF build
  process. Several configure options have been removed, including the
  --with-hdf5 option. (Instead set CPPFLAGS and LDFLAGS to appropriate

In particular, the location of the HDF5, zlib, and (if built into HDF5) the 
szip header files and libraries are now all specified in the CPPFLAGS and 
environment variables, instead of with "--with-hdf5", "--with-zlib", or
"--with-szlib" options.  The new, simpler way to build netCDF-4 with HDF5 is
documented in a simpler installation guide:


So I think things should work by setting LDFLAGS and CPPFLAGS appropriately.

This change was intended to make netCDF work more like other open source 
installations, but it may cause problems initially.  Please let us know if
using environment variables to specify the locations for dependent libraries
and include files doesn't work for you ...
