<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Changing the optimization flags, LDFLAGS and CPPFLAGS will likely fix your problem. The-R/path/to/netcdf/lib will eliminate another problem that I ran into
when trying to run ARWpost.exe in which an error message saying that there was an “error opening shared libraries …”. If you see this message, you can use a command like “ ln –s /path/to/netcdf/lib/libnetcdf* .” issued from the ARWpost directory to link the
necessary libraries and allow them to be referenced.<o:p></o:p></span></p>

<p class="MsoNormal" style="margin-bottom:12.0pt">Dear wrf-users,<br>
<br>
I am having trouble compiling ARWposts. When I try to compile I get lots of error messages looking like this:<br>
<b><i><br>
input_module.f:(.text+0x40f): undefined reference to `ncvgt_'</i></b><br>
<br>
and eventually are confronted with a final error message saying:<br>
<br>
<b><i>make: [ARWpost.exe] Error 1 (ignored)</i></b><i><br>
<br>
</i>Some research has led me to believe that the netCDF on the system might causing this problem and that I might have to re-compile that<br>
Is there any way to go around this perhaps another method of converting wrf output in a format readable by GrADS?<br>
<br>
Kind regards,<br>
