How to Install MCNP4C2 on Mac OS X 10.5.1

Well if you’ve already read my post on installing MCNP on OS 10.4.10 then you mostly know what to do when installing on Leopard! Its nearly identical but with Apple migrating the X11 system they use to the one from X.org the X-window library that MCNP looks for is now a different name so the install fails and tells you it can’t find X11.

Some things are easier though, as X11 is installed by default you no longer have to install it from the Leopard DVD (unless you’ve selected not in install it in a custom installation of Leopard, in which case you probably know that you’ve done it).

Well when you’re at the stage that you’ve run the ./install linux mcnp command and have set the system option to Linux then you have to change the X11 path to the defaults except for the library name. This is now libx11la.lib then the rest f the install will run smoothly.

The new X11 in Leopard is buggy and the windows take an age to draw bit that’s going to be fixed soon. It all works fine its just the geometry plotting that is a bit slow, although this can be sped up if you switch to another app with a window that covers the X11 window during drawing (for example, iTunes), then switch back to find the window is completely drawn.

    I just tested the installation of MCNP5 under 10.5.2.

    Gfortran has major problems with the mcnp5 code, the ABSOFT compiler needs a few adjustemens in the config file and the Intel Fortran Compiler (ifort) compiles the source but if i run the tests it exits with a segmentation fault. Problem seems to be, that the libraries are not correctly linked within the mcnp5 executable. I havent found a solution to this yet.
    Have you tried installing mcnp5 yet?

    Cheers,
    Sascha

    I also would like to know how to install MCNP5 under OS X because the manual is kinda messy…And I hate switching to windows constantly

    And do you perhaps know how to install SCALE4 under OS 10.5.2 ?

    I’m afraid I have no idea what SCALE4 is! Can you enlighten me?

    As for the MCNP5 front, I got it today from the NEA so I’ll let you know when I’ve had a few mins to look through it. I have a feeling I’ll need a trial of either the Absoft Pro or Intel FORTRAN compiler, though.
