[MITgcm-support] MITgcm on Snow Leopard

[Samar Khatiwala]

Dimitris,

I do. But with ifort/gcc. Works fine. You might have to tweak the  
32/64 bit compiler flags. That's gotten a bit tricky.
These are C routines right? I believe the gcc default now is 64 bits.  
If gfortan defaults to 32 bits then that would
explain your errors. Try setting CFLAGS (or whatever it is in the opt  
file) to "-arch i386".
