Hi There,

I am at the end of my rope and i need help!

I am trying to compile a fortran program on my mac (MB Pro 10.6.8).  It uses 
some netCDF stuff, fortran 90, etc...

(A copy of the makefile is pasted below.)

previous versions of this code have compiled here (using netCDF) and are still 
working.

anyway, it builds the .o files fine:

gfortran -O2 -w -ff2c -fbounds-check -static -I/sw/lib/netcdf-gfortran/include  
 -c DataArrays.f90
gfortran -O2 -w -ff2c -fbounds-check -static -I/sw/lib/netcdf-gfortran/include  
 -c Constants.f90
gfortran -O2 -w -ff2c -fbounds-check -static -I/sw/lib/netcdf-gfortran/include  
 -c Deform.f90
gfortran -O2 -w -ff2c -fbounds-check -static -I/sw/lib/netcdf-gfortran/include  
 -c InputOutput.f90
gfortran -O2 -w -ff2c -fbounds-check -static -I/sw/lib/netcdf-gfortran/include  
 -c timestep.f
gfortran -O2 -w -ff2c -fbounds-check -static -I/sw/lib/netcdf-gfortran/include  
 -c swlon.f
gfortran -O2 -w -ff2c -fbounds-check -static -I/sw/lib/netcdf-gfortran/include  
 -c swlat.f
gfortran -O2 -w -ff2c -fbounds-check -static -I/sw/lib/netcdf-gfortran/include  
 -c most_db.f

then it does this:

gfortran -O2 -w -ff2c -fbounds-check -static InputOutput.o Deform.o 
DataArrays.o Constants.o timestep.o swlon.o swlat.o most_db.o 
-L/sw/lib/netcdf-gfortran/lib -lnetcdf -lnetcdff -o most_db
/usr/bin/ld_classic: unknown flag: -no_compact_unwind
collect2: ld returned 1 exit status
make: *** [most_db] Error 1


what are ld_classic and -no_compact_unwind?

Is this even a netCDF issue, or something else entirely?

my gfortran is GCC 4.6.2 and lives in /sw/bin/

i have netcdf libraries in /sw/lib AND in /sw/lib/netcdf-gfortran (i have no 
idea how they ended up in two places, FINK??)
i have netcdf.inc in /sw/include AND in /sw/lib/netcdf-gfortran/include

my netcdf version is 3.6.3 (i think...)

Any insights greatly appreciated!
