John,
I have no experience with the version of the library you are trying to
compile, nor with Snow Leopard yet. However, my ./configure command
is slightly different than yours, esp. note -DgFortran:
./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"

Hi.
System Configuration: OSX 10.6.4
NetCDF Version: 4.1.2-beta1
I am trying to build netcdf-beta in 64-bit mode, with curl support,
to attempt to resolve some apparent problem in building GMTdev with
the latest release. But, as usual, I'm stuck with some arcane
problem that I need some help with. This is an 'old' problem that I
never really understood but somehow worked around but those old
tricks don't seem to work. I've looked at some relatively old
traffic about this and am uncertain what the current state of
affairs is regarding this type of problem. I don't see anything
recent.
Here are the symptoms:
...
checking whether the gfortran linker (/usr/libexec/gcc/i686-apple-
darwin10/4.2.1/ld) supports shared libraries... yes
checking dynamic linker characteristics... darwin10.4.0 dyld
checking how to hardcode library paths into programs... immediate
configure: finding other utilities
configure: trying to set fortran flags for this platform
checking for special C compiler options needed for large files... no
checking for _FILE_OFFSET_BITS value needed for large files... no
configure: displaying some results
checking CPPFLAGS... -Df2cFortran
checking CC CFLAGS... /usr/bin/cc -g -O2
checking type /usr/bin/cc... /usr/bin/cc is /usr/bin/cc
checking CXX... g++
checking CXXFLAGS... -g -O2
checking type g++... g++ is /usr/bin/g++
checking FC... gfortran
checking FFLAGS... -g -O2
checking type gfortran... gfortran is /usr/local/bin/gfortran
checking F90... gfortran
checking FCFLAGS... -qsuffix=cpp=f90
checking type gfortran... gfortran is /usr/local/bin/gfortran
checking AR... ar
checking AR_FLAGS... cru
checking type ar... ar is /usr/bin/ar
checking NM... /usr/bin/nm
checking NMFLAGS...
checking for /usr/bin/nm... /usr/bin/nm
checking nm flags...
checking for C-equivalent to Fortran routine "SUB"... sub_
checking for Fortran "byte"... yes
checking for Fortran "integer*2"... yes
checking if Fortran "byte" is C "signed char"... configure: error:
Could not link conftestf.o and conftest.o
NeptuneStonesteps.local:~/src/netcdf-4.1.2-beta1>~/bin/
makeNetCDF_OSX_beta.bash
And here is the script that I ran to get this:
#!/bin/bash
make distclean
#
export FCFLAGS='-m64'
export CC=/usr/bin/cc
export F77=gfortran
export FC=gfortran
export FCFLAGS=-qsuffix=cpp=f90
export CPPFLAGS='-Df2cFortran'
#
./configure --prefix=/usr/local/netcdf-4.1.2-beta1 --enable-f90 --
with-curl=/usr/local/lib
Assistance would be very helpful since I don't have a working copy
of GMT on this machine at the moment and need one.
Cheers.
