Issues compiling on slc6 against ROOT 6.10/04 #4

Open rdisipio opened 6 years ago

Hi,

I'm having troubles compiling RooUnfold (trunk) against ROOT 6.10/04 on a SLC6 machine. First of all, the makefile looks for a (blabla)/test/Makefile.arch file but it seems located under (blabla)/etc/Makefile.arch . But that's an easy fix. However, the compilation stops because of an incompatibility with the class TBuffer. Is there a known workaround, or can you fix it?

Cheers, Riccardo

Same issue for me also.
