[ncl-install] troubles compiling NCL with PGI and gcc on CentOS

[Tiziana Cherubini]

Hi Mary,

Thank you for your reply. We only purchase the PGI fortran license, and we compile most of our codes with a combination of PGI fortran and gcc. Usually it works. In this instance I was able to get some help from the PGI people and these are the list of libraries they gave me in order to make it work:

-L/usr/pgi/linux86-64/12.9/lib  -lpgmp -lnuma -lpthread -lpgf90 -lpgf90_rpm1 -lpgf902 -lpgf90rtl -lpgftnrtl -lnspgc -lpgc -lrt -lpthread -lm

and that resolves that problem. 

Now I am having an issue with the g2clib (undefined references to the png_set_longjmp_fn function. I believe is due to version inconsistencies between the current version of g2clib (1.4, installed on our system) and the ones used within NCL… and I read on the INSTALL that you recommend to use the package g2clib_with_changes-1.2.1.tar.gz. But I cannot find it. Where can I download this package from ?

Thank you for your help,

Tiziana.
