[Clas12_software] [Clas_offline] compile with ROOT on 64

[Gagik Gavalian]

Dear F.X.,

The line that you sent as a compilation line does not have the flag -m64 
in it, which is needed if you're trying to link with a 64 bit ROOT.
Could you be more specific ?
Are you trying to compile your code as 64 bit and link with 64 bit ROOT ?

Gagik.
