    Hi Malcolm,

    Since you've brought up Mac OS 10.4, I'd like to quickly make a
    statement about it for the benefit of other NCAR Graphics users. Due
    to some issues with MacOS 10.4, we (NCAR employees) are being
    cautioned not to upgrade until some of the issues are resolved. As a
    result, I can't make any statements yet about compatibility between
    binaries built under 10.3 and how they will work under 10.4.

    I assume you are talking about Absoft's xlf? Is so, NCAR Graphics
    cannot be be built with this xlf due to a problem in the way the
    compiler handles the initialization of common block variables in block
    data statments. (Basically, the variables don't get initialized.)
    I've had many conversations with Absoft about this problem, and they
    have not given me a date on when they plan to fix this bug.

    There is a work-around, but it's a bit hideous. It requires that you
    link with individual *.o files instead of the NCAR Graphics libraries
    (libncarg.a, libncarg_gks.a, etc). This means that you have to link
    to hundreds of *.o files! To me, this is an unreasonable work around,
    and prone to error, so I've decided to wait until Absoft fixes the
    bug.

    I am happy to provide the config file I used, in case Absoft has
    fixed the bug. I've attached it to this message, "Darwin.absoft".

    Cheers, and good luck!
