 Hi,

 I have installed gcc45 and netcdf +gcc45 on a mac running 10.5.8 and have
 tested the install on a simple fortran code which calls the netcdf
 library.  When I compile this code I get the error:


 [cassava:~] serra% gfortran -I/opt/local/include handle_err.f -o
 handle_err -L/opt/local/lib -lnetcdf
 Undefined symbols:
   "_main", referenced from:
       start in crt1.10.5.o
   "_nf_strerror_", referenced from:
       _handle_err_ in ccJcyNUi.o
 ld: symbol(s) not found
 collect2: ld returned 1 exit status

 I've had trouble before with macports netcdf libs not working with fortran
 and ended up creating my own Portfile.  But that installation will not
 work any more.  I think because I upgraded all my macports code and hdf5
 is now hdf5-18.  I did try to fix the problem by installing hdf5-18 +gcc45
 and then reinstalling netcdf but this did not fix the problem.

 I rely on the netcdf libraries every day in my work so desperately need to
 fix this issue!

 Thanks.
