[ncl-install] 64-Bit Libraries on Mac OS X

[Mary Haley]

The reason why it works with the older version of NCL is because this version doesn't have cairo dependencies, and hence doesn't need the cairo libraries.

You didn't include your compile line or error messages, so I'm not sure exactly what the problem is with V6.1.2. My guess is that you either don't have the proper -lcairo, etc, lines in the link phase, or else you need some -L options to help your compiler find the cairo libraries.

Since you are using NCAR Graphics, I agree, there's probably no reason why you need to link against V6.1.x.

When I changed the NCARG_ROOT to point to 6.0, this trouble vanished.  The binaries that I've downloaded have all been for my operating system version (I think).  When I ran the file command on the libcairo.dylib in /usr/X11R6/lib and /usr/X11/lib, it shows that it's built for both 64-bit and 32 bit.

Anyways, I got RIP to compile with this older version, and so I'm satisfied.  I'm still using the newest version of NCL for my graphics purposes, due to the updates for WRF output and such that are extremely handy.

The make output then says that it can't find a bunch of libraries related to cairo for x86_64 architecture.  I finally got it to compile using the binary for 6.0.  Is there any chance you guys created the Mac binary for 6.1.2 without specifying a 64 bit flag?
