Ryan,
I do have the hd5 installed yes. It is under /usr/local/lib
and /usr/local/include. When I installed WRF two years ago these are
required libraries. What I saw in this URL is
http://bryanwweber.com/writing/personal/2014/01/11/installing-numpy-scipy-on-ubuntu-12.04.3-from-scratch-source-with-intel-compilers/
I need to make changes to the intelcompiler.py file so that it reflects my
environment. How I do not know yet.
Regards,
Ashwin.
