Aloha.

I've installed earlier versions of netCDF many, many times but I've been away 
from it for  a few years (maybe more than a few).

Anyway, I'm trying to install on OSX 15.5 (Sequoia) on Apple M2 hardware.  I've 
(apparently) successfully installed hdf5-1.14.6 and am not trying to compile NC 
against it.  But when I run this ...


CPPFLAGS='-I/Users/hellyj/src/hdf5-1.14.6/Build/include' \
LDFLAGS='-L/Users/hellyj/src/hdf5-1.14.6/Build/lib'  \
./configure --prefix=/Users/hellyj/src/netcdf-c-4.9.3/Build  --enable-netcdf-4 
--enable-f90  --with-hdf5=/Users/hellyj/src/hdf5-1.14.6/Build
make check install

This is what happens:


configure: error: Compiling a test with HDF5 failed.  Either hdf5.h cannot be 
found, or config.log should be checked for other reason.

+ make check install


When I look at config.log the only error I find is:


configure:4531: $? = 0

configure:4520: gcc -V >&5

gcc: error: unrecognized command-line option '-V'


Which seems to be a problem with gcc arguments.  However, not sure how to 
correct this in the 'configure' script or if it should be happening at all.


Any advice is very welcome.
