[netcdfgroup] 64-bit build with Snow Leopard?

Hi

Has anyone successfully built NetCDF 4 as 64-bit, on a Mac Pro with Snow Leopard and the 64-bit kernel enabled?

I'm hitting problems with the F77 interface, i think. I've set all compiler flags I can find to '-m64' (just using GNU/free compilers, no Absoft etc).

Configure line:

ianharris% arch -arch x86_64 ./configure --with-hdf5=/usr/local -- with-zlib=/usr/local --with-szlib=/usr/local --prefix=/usr/local -- disable-f90 --enable-netcdf-4 --enable-64bit

(I have tried it with and without the 'arch' prefix, it doesn't seem to help)

If I specify G77 as the compiler, it doesn't seem to like the -m64 option:

:
checking for C-equivalent to Fortran routine "SUB"... configure: error: Could not compile conftest.f
:

If, on the other hand, I specify gfortran, it compiles the tests but then fails thusly:

:
checking if Fortran "byte" is C "signed char"... configure: error: Could not link conftestf.o and conftest.o
:

I modded configure so it didn't delete those two files.. this is the real problem I think:

:
ianharris% file conftestf.o conftest.o
conftestf.o: Mach-O 64-bit object ppc64
conftest.o:  Mach-O 64-bit object x86_64
:

In the config.log file, this is the relevant bit (I think):

:
configure:24126: checking for C-equivalent to Fortran routine "SUB"
configure:24133: /usr/local/bin/gfortran -c -m64 conftest.f
configure:24136: $? = 0
configure:24148: result: sub_
configure:24170: checking for Fortran "byte"
configure:24178: /usr/local/bin/gfortran -c -m64 conftest.f
configure:24181: $? = 0
configure:24183: result: yes
configure:24201: checking for Fortran "integer*2"

configure:24212: $? = 0
configure:24214: result: yes
configure:24241: checking if Fortran "byte" is C "signed char"
configure:24251: cc -c -m64 -m64 conftest.c

configure:24254: $? = 0
configure:24257: /usr/local/bin/gfortran -m64 -c conftestf.f
configure:24260: $? = 0
configure:24263: /usr/local/bin/gfortran -o conftest -m64 conftestf.o conftest.o ld: warning: in /usr/lib/crt1.10.5.o, missing required architecture ppc64 in file

collect2: ld returned 1 exit status
configure:24266: $? = 1
configure:24289: error: Could not link conftestf.o and conftest.o
:

Now, this really isn't my area of expertise (um, as keen blogwatchers will know ;) but it looks to me as though gfortran isn't working as a 64-bit compiler?

All compilers and supporting externals were built with the 64-bit kernel installed and compiler env variables set '-m64'. As far as I know.

If anyone has any suggestions.. that would be just great!
