<p>Dear Beni,</p>
<p>The cling compiler, which is used since root version 6 for
macros, has to know about the DSelector library. It is not enough
to load it inside the macro (gROOT->ProcessLine(".x
Load_DSelector.C").</p>
<p>If you add the following line to the header section of your
macro, besides the #include statements, it will work:</p>
<p>R__LOAD_LIBRARY(libDSelector)</p>
<p>Cheers,</p>
<p>Alex<br>
</p>

<font size="+1"><tt>Hi All,<br>
I have a weird issue. When trying to use proof with the
DSelector the command<br>
DPROOFLiteManager *dproof = new DPROOFLiteManager();<br>
works perfectly when using it directly in an active root
session.<br>
However if I use the same line in a root script it does not
work and gives me<br>
the error that DPROOFLightManager is not defined.<br>
<br>
any idea what is going on here?<br>
<br>
Beni<br>
