[ncl-install] Fwd: Have anybody installed ncarg on Mac OS 10.6

Hi Mary,

Thanks for the hint. Now WRAPIT works with 64-bit compiler (gcc and gfortran) in 32-bit ncl.

Here is what I did:
Searching "case Darwin" in WARPIT

First coming: 
   if ($debug == 1 && ($f90c == g77 || $f90c == gfortran)) then     # GNU 
     set fopts = "$fopts -v -c -m32 -fno-common -ffortran-bounds-check -fno-second-underscore"
   else
     set fopts = "$fopts -c -m32 -O -fno-common -fno-second-underscore"

Second coming:
   if ($debug == 1) then
     set cmd = "gcc $copts -c -m32 -fno-common -I${NCARG_ROOT}/include WRAPIT.c"
     echo $cmd
   else
     set cmd = "gcc $copts -c  -m32 -fno-common -O -I${NCARG_ROOT}/include WRAPIT.c"

Third coming:
 case Darwin:                      # MacOSX
   if (-e /sw/lib/libg2c.a) then
     set cmd = "gcc -m32 -bundle -flat_namespace -undefined suppress $ld_suffix -L/sw/lib -lg2c"
   else
     set cmd = "gcc -m32 -bundle -flat_namespace -undefined suppress $ld_suffix"
   endif
   if ($f90c == gfortran) then     # gfortran compiler
       set cmd = "$cmd -m32 -lgfortran"
   endif
   if ($f90c == g95) then          # g95 compiler
     set cmd = "$cmd -m32 -lf95"
   endif


I like to build a 64-bit ncl for Snow leopard if I can get help form you. But I only can do it at weekend. I have more free time.
