Hello All,<br><br>Initially, I went through the same problem as you guys did. If you are using version 1.9 of grads migrate to the latest opengrads 2.0.a9.oga.1<br>I downloaded the binary version of opengrads 2.0.a9.oga.1 for FC14 and what I did to resolve the issue of " 're' not a variable or function name"<br>
was to set the environment variables GA2UDXT and LD_LIBRARY_PATH to point to the right path which depends on your installation such as:<br><br>GA2UDXT=/opt/Opengrads/Contents/Linux/Versions/2.0.a9.oga.1/x86_64/gex/udxt<br>
LD_LIBRARY_PATH=/opt/Opengrads/Contents/Linux/Versions/2.0.a9.oga.1/x86_64/gex:$LD_LIBRARY_PATH<br><br>(I am not sure whether the second variable LD_LIBRARY_PATH is necessary?)<br><br>Make sure that you put them in your .bashrc or .bash_profile to make it permanent.<br>
<br>Hope this helps and good luck!<br><br><br>Garut<br><br><div class="gmail_quote"><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">

The extension re() is supposed to be include in all opengrads builds. Which<br>
operating system are you using? Please send output of<br>
<br>
ga-> q config<br>
ga-> q udx<br>
<br>
Did you do the regular opengrads bundle installation ("untar and go") or<br>
did you perform the "classic installation"?<br>
<br>
