Re: Problem wiith name mangling of template classes in dictionary files after changing optimisation flag...

Hi Pierre-Luc,

interesting! At least as a first step you should try to compile all of CINT with -ip instead of -ipo; simply set CINTCXXFLAGS in the Makefile.icc* that you used. Let me know if that helps.

On the other hand, most of ROOT is functions that are meant to be callable by users. It's not a boxed piece of software, so I am not sure how much you really gain by multi-file optimization.

Cheers, Axel.
