Re: ng4ex

Liu,

It looks like there is a mismatch between the version of the compilers that you are using to compile cn01f.f, and the version that the HLU and NCAR Graphics libraries were built with.

Do you actually have HLU code that you need to compile? If not, I wouldn't worry about this particular example not working. If "ncl" is working:

   ng4ex cn01n

and that's all you plan to use, then you should be okay.
