Re: [ncarg-talk] NCL build errors

Hi Prabhakar,

First, as you're building NCL, your questions are best addressed to
the 'ncl-talk' mail list. More info may be found at:

This error indicates that you've built portions of NCAR Graphics and
NCL with the gfortran compiler, but have not instructed the
build process to use gfortran's library when linking. In the $NCARG/
config/LINUX configuration file (it appears you are building on
a Linux host), you'll need to specify '-lgfortran' as part of the
defined macro 'CtoFLibraries', as in (for example):

#define CtoFLibraries -lgcc -lg2c -lgfortran -lm

This problem generally results from the source file 'wrapit.c'
being somehow clobbered, usually due to a timing race condition
during the build process on faster hosts. Please see the second
bullet point at this web link:

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

and, even though the error message shown there is not what you see,
follow the directions to download a new version of 'wrapit.c'
and rebuild.

Please let me/us know if this does not address your problems.
