Hi All,<br>
<br>
I managed to run our installation scripts almost to the end compiling<br>
and linking<br>
the GlueX software in Ubuntu 22.04.<br>
The last hurdle to take is linking hdgrean4 where it fails due to<br>
messages like this<br>
.....<br>
undefined reference to `TCrossSection::PairProduction(TPhoton const&,<br>
TLepton const&, TLepton const&)'<br>
undefined reference to `TCrossSection::TripletProduction(TPhoton const&,<br>
TLepton const&, TLepton const&, TLepton const&, TLepton const&)'<br>
<br>
anyone knows in which library these methods are supposed to be in?<br>
<br>
<br>
cheers,<br>
Beni<br>
