<div>Dear Gus Correa<br>
</div>
<div><br>
</div>
<div>I tried to create a link libgfortran.so.3 to libgfortran.so.5 <br>
</div>
<div>but I got another error<br>
</div>
<div>ncl: /usr/lib/x86_64-linux-gnu/libgfortran.so.3: version `GFORTRAN_1.4' not found (required by ncl)<br>
</div>
<div><br>
</div>
<div>I would like to not use the virtual environment for now<br>
</div>
<div>SO I tried to compile and install from the source code ncarg-6.6.2<br>
</div>
<div>following the step-by-step instructor from the website<br>
</div>
<div> <br>
</div>
<div>After I installed all the necessary package on the /usr/local/ and<br>
</div>
<div>run the command: make Everything >& make-output<br>
</div>
<div>I end up with the below executables:<br>
</div>
<div><br>
</div>
<div>But there is not 'ncl' <br>
</div>
<div><br>
</div>
<div>bash: ncl: command not found<br>
</div>
<div><br>
</div>
<div>What did I miss? <br>
</div>
<div><br>
</div>
<div>Many Thanks<br>
</div>
<div>Francesco<br>

<div>Hi Francesco</div>
<div><br>
</div>
<div>Have you checked if your Debian distribution has a "compat" (compatibility) package for gfortran/libgfortran</div>
<div>between libgfortran.5 and libgfortran.3 ?</div>
<div>Apt-get may have a way to check if it is available.<br>
</div>
<div>I don't use Debian, but CentOS-7, which has an older kernel and older libraries.</div>
<div>However, I have libgfortran.3 along with a "compat" package that provides compatibility with libgfortran.1, for example.</div>
<div><br>
</div>
<div>An alternative is to install NCL using Anaconda Python.</div>
<div>This is currently the recommended method (argh!):</div>
<div><a href="https://www.ncl.ucar.edu/Download/" target="_blank">https://www.ncl.ucar.edu/Download/</a></div>
<div>That is self-contained, doesn't depend on the system libraries.</div>
<div>In my experience it has other problems, particularly a sensitive dependency on other Anaconda Python packages</div>
<div>that change by the hour, and don't give a damn to backward compatibility, which can easily break functionality.<br>
</div>
<div>So, if you install this way, be careful with any conda packages updates, or simply don't update.</div>
<div><br>
</div>
<div>I hope this helps,</div>
<div>Gus Correa<br>
</div>
