<html><head><meta http-equiv="Content-Type" content="text/html charset=utf-8"></head><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;" class="">Hi Jean,<div class=""><br class=""></div><div class="">This is a common issue experienced when installing NCL using “apt-get” on Ubuntu. The package maintainers for Ubuntu chose to split certain files that we normally put in “$NCARG_ROOT/lib/ncarg” (“/usr/<b class="">lib</b>/ncarg” in your case) into their own directory “/usr/<b class="">share</b>/ncarg”. You can configure NCL to use this directory with “export NCARG_NCARG=/usr/share/ncarg”, although it looks like the script you are running explicitly references “$NCARG_ROOT/lib/ncarg” which would need to be changed. You can read about the various NCARG_* environment variables here: <a href="https://www.ncl.ucar.edu/Document/Language/env.shtml" class="">https://www.ncl.ucar.edu/Document/Language/env.shtml</a></div><div class=""><br class=""></div><div class="">To avoid some of these complications, you may want to consider installing a binary release of NCL from our website: <a href="http://ncl.ucar.edu/Download/" class="">http://ncl.ucar.edu/Download/</a></div><div class=""><br class=""></div><div class="">Alternatively, if you’re familiar with Anaconda/“conda”, you could install NCL using the “conda” package manager: <a href="http://ncl.ucar.edu/Download/conda.shtml" class="">http://ncl.ucar.edu/Download/conda.shtml</a></div><div class=""><br class=""></div><div class="">Also, the version of NCL provided by the Ubuntu package manager is 6.3.0, while NCL 6.4.0 was released 4 months ago (and is available via either of the installation methods listed above). This might not matter to you if you’re just experimenting with NCL, but I thought I’d let you know in case you would prefer to use the newest version.</div><div class=""><br class=""></div><div class="">I hope this helps,</div><div class="">Kevin</div><div class=""><br class=""><div><blockquote type="cite" class=""><div class="">On Jul 5, 2017, at 4:19 PM, Jean P Valle Rodriguez <<a href="mailto:jean.valle@upr.edu" class="">jean.valle@upr.edu</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div dir="ltr" class=""><div class="">I am currently working the tutorial of WRF and the first step is the plotgrids part.
