[MITgcm-devel] Beaufort experiment on mac os x

[Torge Martin]

Oh, I changed just the Makefile but did not start my tests with genmake.

Thanks, Dimitris, this works!

changes to darwin_amd64_gfortran:

NOOPTFLAGS='-O0'
### NOOPTFILES=''
NOOPTFILES='ini_masks_etc.F gmredi_calc_psi_bvp.F'

but you have to be careful because these variables are reset later in 
the optfile if option -ieee is not used:

if test "x$IEEE" = x ; then
     FFLAGS="$FFLAGS -Wunused -Wuninitialized"
     FOPTIM='-O3 -ftree-vectorize -funroll-loops'
     NOOPTFLAGS='-O2 -funroll-loops'
     NOOPTFILES='gad_c4_adv_x.F gad_u3_adv_x.F'
else
     FFLAGS="$FFLAGS -Wunused"
     FOPTIM='-O0'
fi

this should be changed to:

if test "x$IEEE" = x ; then
     FFLAGS="$FFLAGS -Wunused -Wuninitialized"
     FOPTIM='-O3 -ftree-vectorize -funroll-loops'
else
     FFLAGS="$FFLAGS -Wunused"
     FOPTIM='-O0'
fi
