Re: need help linking

Jason,

The "icfell" and "seter" symbols should be in the "ncarg" (libncarg.a)
library. There can be a couple of things wrong here.

One is maybe your compiler is expecting there to be underscores
appended after the name of every Fortran subroutine in the library,
but NCAR Graphics was compiled such that these underscores were
removed.

The second possibility is that these symbols just didn't get compiled
into the library for some reason, but this is unlikely.

Can you type the following and let me know what it says:

    nm $NCARG_ROOT/lib/libncarg.a | grep icfell
    nm $NCARG_ROOT/lib/libncarg.a | grep seter

Also, did you build NCAR Graphics from source, or install from a
pre-compiled binary? If you built from source, which compilers did you
use? If you used a binary, which one did you download?

Thanks,

--Mary
