[MITgcm-support] compiling problems

[Martin Losch]

Hi Andreas,

I have no idea, what compiler you are using, but “relocation” would make me think that the compiler/loader cannot allocate the size of the executable/fields within the executable (that’s an error that I often get with gfortran/ifort). Since reducing the tiles makes the problem go away, I would guess that size is the problem and you may need additional compiler flags (‘—no-relax’?).
