[Clas12_software] Compiling Root on Mac OS Mountain Lion

[Veronique Ziegler]

Hi, 

  for folks needing to install Root for their analyses on a Mac with Mountain Lion OS, 
these are the instructions that enabled me to successfully install and build:

svn co http://root.cern.ch/svn/root/trunk root  

(see http://root.cern.ch/drupal/content/installing-root-source)


Following these instructions from the Root developers who indicated that 
something had been fixed recently in the OSX 10.8 build of ROOT trunk. 
After you have checked out root, please do:

cd root
svn up
./configure
make distclean
make

this should work in building the Cocoa backend version of ROOT free of X11.

Cheers, 

Veronique.
