Hi,
Something got shorted in my mind ... and I can't recall how to make my
nice "template <class _FLT> class Complex" visible in ROOT (from a shared
library). I don't want to inherit from TObject, nor to use ClassDefT(2) as
they both add private data members.
So, how should the LinkDef look like ?
Thanks in advance,
Jacek.
P.S. Anyhow, I tried to inherit from TObject and use ClassDefT(2) and I got :
