Re: Installing NCAR graphics on MacPro with OS 10.6.2 with 64 bits

Hi David,

There are problems building on these new 64-bit mac systems, because
they "look" like a 32-bit system to some software builds.

I think (hope) the fix in this case may be that the "libncarg_c.a"
library doesn't have the correct files being built, because it thinks
you're on a 32-bit system.

Try this fix:

Edit the file $NCARG/common/src/libncarg_c/yMakefile and change the
line:

#elif defined(Darwin) && defined(i386)

to:

#elif defined(Darwin) && defined(i386) && !defined(__LP64__)

Then, right above this line, add the following lines:

#elif defined(Darwin) && defined(i386) && defined(__LP64__)
EXCSRCS = bcopyswap.c logic32.c
EXFSRCS = gbytes.f sbytes.f
EXOBJS = sbytes.o gbytes.o bcopyswap.o logic32.o

To make sure the correct files get built, save this file, and in the
same directory, type:

make clean
make me
make includes depend all install

(make sure it used "-m64").

Type

   ls *.o

and make sure you see the following files:

argget.o error.o logic32.o rwchinfl.o
version.o
atoargv.o gbytes.o misc.o sbytes.o
bcopyswap.o i1mach.o ncarg_path.o sdbm.o
d1mach.o iargct.o options.o trnspprt.o
env.o lblank.o r1mach.o usleep.o

If you see "gsbytes.o" and not "sbytes.o" and "gbytes.o", then your
code will continue to seg fault.

If you don't see "gsbytes.o", then give your "make Everything" a try
again, making sure again that
you are using -m64. You can do this by adding "-m64" to the
CcOptions and FcOptions line
in the file $NCARG/config/Darwin_Intel.
