My Mac is a 64-bit Mac Pro with 12 GB RAM. The kernel may be 32-bit (uname -a says i386), but that may not be definitive (OS X configures the kernel dynamically at boot.) (I never paid that much attention to it.) Regardless, 64-bit applications are supported. The Intel compilers (icc/icpc/ifort) default to 64-bit, but the GNU compilers (gcc/g++/g95/gfortran) do not.

Thanks, Larry. I think that's true if you install the 32-bit Snow Leopard kernel. I'll check what this is actually compiling as if I can figure out how to do that on OSX. 


Cheers.

John,
My recollection using gcc and gfortran on Mac OS X 10.5 (Leopard) is that they both default to 32-bit. My makefiles define CC (and, sometimes, LD) as "gcc -m64", plus FC as "gfortran -m64" to get things to work. Note: the -m64 flag is NOT in defined in the CFLAGS, FCFLAGS and LDFLAGS variables -- since -m64 is really selecting a different compiler/linker, it should be defined as part of those variables, regardless of the rest of the options.
For example, here's my (non-HDF) make configure of netCDF using gcc/g ++/gfortran: 

        cd netcdf-$(VERSION) ; \
        ./configure >configure.log 2>&1 \
           CC="gcc -m64" \
           CFLAGS="-g -O2" \
           CXX="g++ -m64" \
           CXXFLAGS="-g -O2" \
           CPPFLAGS="-DNDEBUG -DgFortran" \
           FC="gfortran -m64" \
           FCFLAGS="-g -O2"
(I haven't tried -O3, which supposedly invokes the gcc vectorizer/ sse code generator.)

Hi.
I copied all the source (netcdf-beta.tar and hdf5-1.8.5) to another mac and upgraded Xcode and then installed the gfortran you specified and bingo.

iceberg:netcdf-4.1.2-beta1 hellyj$
Here's the script I used. Note that this is a 64bit build since I turned off the -m32 option. At least I think it defaults to 64-bit. 

#!/bin/bash
make distclean
#export LDFLAGS="-L/usr/local/hdf5-1.8.5-macosx32-static"
#export DYLD_LIBRARY_PATH=/usr/local/hdf5-1.8.5-macosx32-static: $DYLD_LIBRARY_PATH 
export DYLD_LIBRARY_PATH=/usr/local/hdf5-1.8.5:$DYLD_LIBRARY_PATH
#export LD_LIBRARY_PATH=/usr/local/hdf5-1.8.5-macosx32-static: $LD_LIBRARY_PATH 
#
echo "LD_LIBRARY_PATH: $LD_LIBRARY_PATH"
echo "DYLD_LIBRARY_PATH:$DYLD_LIBRARY_PATH"
export CC=/usr/bin/cc
#export CFLAGS='-m32'
#export CPPFLAGS=-Df2cFortran
export F77=gfortran
export FC=gfortran
export FCFLAGS=-qsuffix=cpp=f90
./configure --prefix=/usr/local/netcdf-4.1.2beta --enable-netcdf-4 --enable-f90 --with-hdf5=/usr/local/hdf5-1.8.5
#./configure --prefix=/usr/local/netcdf-4.1.1 --enable-netcdf-4 -- enable-f90 --with-hdf5=/usr/local/hdf5-1.8.5-macosx32-static 
#
#export LDFLAGS="-L/usr/local/hdf5-1.8.5-macosx64-static"
#./configure --prefix=/usr/local/netcdf-4.1.1 --enable-netcdf-4 -- enable-f90 --with-hdf5=/usr/local/hdf5-1.8.5-macosx64-static
I'm going to try to reproduce this on my laptops where I was having the previous problems. 

Cheers.

Hi John:
I notice you are using HDF-1.8.5. A few days ago I emailed the list about that, and Ed replied that at the moment they do not work with HDF-1.8.5 (i can't find the email but look at the archives). You need to use the version of HDF 1.8.4 that is on the netcdf ftp site. I have been able to compile that with: 

1.  the gcc and gfortran from fink
2. the gcc from apple and the gfortran from R at: http://r.research.att.com/tools/ - make certain you scroll down and get the gfortran for Snwo Leopard, not the one at the top of the page. 

HTH,

Greetings.
I am struggling to compile netcdf-4.1.1 on OSX 10.6.4 with hdf5 and fortran so I can build Dave Pierce's new ncview. I have worked my way through some earlier problems and have come to this script: 

#!/bin/bash
make distclean
#export LDFLAGS="-L/usr/local/hdf5-1.8.5-macosx32-static"
export CC=/usr/bin/cc
export CFLAGS='-m32'
#export CPPFLAGS=-Df2cFortran
export F77=gfortran
export FC=gfortran
export FCFLAGS=-qsuffix=cpp=f90
./configure --prefix=/usr/local/netcdf-4.1.1 --enable-netcdf-4 -- enable-f90 --with-hdf5=/usr/local/hdf5-1.8.5-macosx32-static 
#
#export LDFLAGS="-L/usr/local/hdf5-1.8.5-macosx64-static"
#./configure --prefix=/usr/local/netcdf-4.1.1 --enable-netcdf-4 -- enable-f90 --with-hdf5=/usr/local/hdf5-1.8.5-macosx64-static
This got me past some earlier problems with 32-bit fortran libraries (I think) but now I'm getting complaints about the hdf5 libraries even though they seem to be found for some things. 

checking for manual-page index command...
checking hdf5.h usability... yes
checking hdf5.h presence... yes
checking for hdf5.h... yes
checking whether we should try to build netCDF-4... yes
checking for H5Fflush in -lhdf5... no
configure: error: Can't find or link to the hdf5 library. Configure with --disable-netcdf-4 or see config.log for errors.
I'm attaching the config.log for those who might care to look. In the script above, you can see that I experimented with defining the LDFLAGS and this solved the problem of the missing -lhdf5 but introduced a bunch of other even stranger problems that made me think I was overriding some more basic library paths by specifying LDFLAGS. Anyway, I couldn't figure out what those problems were so I backed up to this in hoping that someone out there would have a suggestion. 

Any help would be appreciated.

Cheers.
