Re: Should ROOT be recompiled after upgrade from FC12 to FC14?

Hi,

This is independent of ROOT: either FC12 and 14 are binary compatible or not. I don't know the answer, but I would warmly recommend you to rebuild ROOT just in case something changed.

What you observe for Windows cannot be mapped directly to Linux: Windows has 30 years of backward compatibility (I am exaggerating slightly :-) and it pulls in binary incompatibility through Visual Studio / C++: if you update that you'll have to rebuild ROOT.

Cheers, Axel.
