Hello,
I have a perl script that calls an NCL script via the perl function system()
that does not seem to be working quite right.
I'm running NCL 4.2.0.a030 on Red Hat 8.
When I run the perl script from the command line everything works great, but
when I set up a cron job to run the script, the resulting error message is:
warning:Unable to Get System Resource File Name?
warning:Unable to load System Resource File (null)
fatal:GetSysAppDir:Unable to get a default value for the system App Resource
directory
warning:["Resources.c":721]:Unable to set appSysDir to default value - Using
NULL
fatal:GetSysAppDir:Unable to get a default value for the system App Resource
directory
warning:["Resources.c":721]:Unable to set appSysDir to default value - Using
NULL
warning:Unable to Get System Resource File Name?
warning:WorkstationClassInitialize:Unable to access rgb color database -
named colors unsupported:[errno=2]:No such file or
directory
warning:["Palette.c":1525]:NhlLoadColormapFiles: Invalid directory
encountered in colormap path specification
The simplest possible perl script looks something like:
#! /usr/bin/perl
system("/home/me/script.ncl")
My ncl script uses:
load "/usr/local/ncarg/lib/ncarg/nclex/gsun/gsn_code.ncl"
load "/usr/local/ncarg/lib/ncarg/nclex/gsun/gsn_csm.ncl"
rather than the "load "$NCARG_ROOT/lib/ . . . " references.
So, when run from cron with
* * * * * /home/me/perlscript.pl
the process generates the above message.
Any suggestions,
Thanks,
Jan
