[ncl-install] Trouble with NCL 6.4.0 (symbol not found _ZdaPvm)

[Mary Haley]

Andrea,

You are the third person to report this problem.  The first person said
that what worked for him was to upgrade his MacPort installation.  I'm
waiting to hear back from the second person as to whether this solution
works for him as well.

I think the issue is that we used the HPC GNU compilers to build NCL, and
if you have the MacPort version of the compilers, then this missing symbol
shows up if your MacPorts is old.

Have you updated MacPorts since upgrading to Sierra?

The other possible solution is to download the HPC version of the GNU
compilers, which will get installed to /usr/local and hence won't overwrite
your MacPorts version that's in /opt/local. Follow this link for more
details:

If you find the solution, can you let me know so I can make sure other
users are aware of it?

Thanks,

--Mary
