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.
