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

[Mary Haley]

Is it possible you are just missing a "-lpng" on the compile line?

You can get our version of the g2clib from:

http://www.ncl.ucar.edu/Download/build_from_src.shtml#GRIB2

This also includes instructions on how to build GRIB2 to work with NCL.

I'll include the list of libs that the PGI folks recommended in our LINUX.64.PGI file for future reference. Thanks for providing it.

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:

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 ?
