Netcdf builds as a static library only by default. The configure options below are for a v3-style build needed by GDAL, without fancy extras (HDF, DAP, libcf).

In the netcdf source:

export MACOSX_DEPLOYMENT_TARGET=10.6
./configure --disable-dependency-tracking --enable-c-only --disable-dap --without-libcf --enable-utilities \
CFLAGS="-Os -arch i386 -arch x86_64 -D_FILE_OFFSET_BITS=64"

After configuration, edit config.h and add at the end:

#undef SIZEOF_LONG
#ifdef __LP64__
#define SIZEOF_LONG 8
#else
#define SIZEOF_LONG 4
#endif
#undef SIZEOF_SIZE_T
#ifdef __LP64__
#define SIZEOF_SIZE_T 8
#else
#define SIZEOF_SIZE_T 4
#endif

make
sudo make install

In the netcdf source:

export MACOSX_DEPLOYMENT_TARGET=10.5
./configure --disable-dependency-tracking --enable-c-only --disable-dap --without-libcf --enable-utilities \
CFLAGS="-Os -arch ppc -arch i386 -arch ppc64 -arch x86_64 -D_FILE_OFFSET_BITS=64"

After configuration, edit config.h and add at the end:

#undef SIZEOF_LONG
#ifdef __LP64__
#define SIZEOF_LONG 8
#else
#define SIZEOF_LONG 4
#endif
#undef SIZEOF_SIZE_T
#ifdef __LP64__
#define SIZEOF_SIZE_T 8
#else
#define SIZEOF_SIZE_T 4
#endif

make
sudo make install

In the netcdf source:

export MACOSX_DEPLOYMENT_TARGET=10.4
./configure --disable-dependency-tracking --enable-c-only --disable-dap --without-libcf \\
CFLAGS="-Os -arch ppc -arch i386 -D_FILE_OFFSET_BITS=64 -isysroot /Developer/SDKs/MacOSX10.4u.sdk"
make
sudo make install
