Hi Manuel,
to make a compiled global visibile from the interpreter add:
#pragma link C++ global gHades;
in your LinkDef.h file. See also:
http://root.cern.ch/cgi-bin/print_hit_bold.pl/root/roottalk/roottalk97/0442.html?pragma#first_hit
Yor code just becomes:
Hades::Hades()
{
gHades = this;
...
}
Cheers, Fons.
