Re: [netcdfgroup] installing netCDF with --enable-hdf4
pseudo netcdf calls in the HDF4 library, that if the two are compiled and linked together (netcdf3, hdf4) there are collisions and things fail.
yes, HDF4 has a netCDF3 version included in it (version around 1996 ? ) ...probably little know fact.
There is an option in the HDF4 configure that you need to set when you are going to be linking both libraries, but I can't remember which. 

HDF4 has this option

--enable-netcdf
but I got the same netCDF4 linking errors with either option (--enable-netcdf /disable-netcdf ) 

there are some warnings in netCDF with

--enable-hdf4

checking mfhdf.h usability... yes
checking mfhdf.h presence... no
configure: WARNING: mfhdf.h: accepted by the compiler, rejected by the preprocessor! 
configure: WARNING: mfhdf.h: proceeding with the compiler's result
checking for mfhdf.h... yes
checking for Hclose in -ldf... no
checking for SDcreate in -lmfhdf... no

Oops I sent the following to Chris, meant to send to all:
My memory (and I am old and don't remember too well) is because of the pseudo netcdf calls in the HDF4 library, that if the two are compiled and linked together (netcdf3, hdf4) there are collisions and things fail. There is an option in the HDF4 configure that you need to set when you are going to be linking both libraries, but I can't remember which. You might do better posting this to the hdf help list.

I tried an opposite approach to yours, starting with the near-minimum, --enable-netcdf4 --enable-hdf4, and it compiled all the way through, including ncgen3. However, one of the make checks failed to compile, interops3. Anyway, perhaps that is worth trying: start with just --enable-hdf4 and then add in options after that until it fails.
If the minimal approch still doesn't work, note that your LDFLAGS environment has to be set to find the HDF4 libraries, e.g., LDFLAGS=-L/wherever/your/libdf.a/is/located.

I build and install HDF5, then HDF4, then (attempt to build) netCDF4:

# HDF5 ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf-4/hdf5-1.8.9.tar.gz
./configure --prefix=/usr/local --enable-cxx --enable-fortran
make;sudo make install
# HDF4 http://www.hdfgroup.org/ftp/HDF/HDF_Current/src/hdf-4.2.9.tar.gz
./configure --prefix=/usr/local --enable-fortran
make;sudo make install
# netCDF4
LDFLAGS='-L/usr/local/lib' ./configure --prefix=/usr/local
--enable-shared --enable-dap --enable-hdf4 --enable-logging
--enable-netcdf4 --enable-v2
make

The steps above all work fine with the simple change to --disable-hdf4.
With --enable-hdf4 the netCDF make command fails in the ncgen3 section:
