RPMS of ROOT 3.00.06 (released 2001.03.13) are available for RedHat Linux 6.1 Intel at ftp://ftp.slac.stanford.edu/users/langston/root/. There are three RPMS for this version of ROOT that you may download: root-gcc-c++-2.95.2-3.00.06-1.i386.rpm root-gcc-c++-2.95.2-examples-3.00.06-1.i386.rpm root-gcc-c++-2.95.2-documentation-3.00.06-1.i386.rpm NOTES: 1) These RPMS were compiled with the g++ from gcc 2.95.2: 2) The 3.00.06 RPMs have True Type font support compiled in, and come with the fonts you need, so everything should work "out of the box". 3) This release of ROOT contains the "switch_root" utility, which lets the user easily switch between multiple versions of ROOT installed on their system. To run it, just type "switch_root". 4) If you want a version of ROOT that works with the default g++ that comes with RedHat 6.1 (e.g. egcs-2.91.66, otherwise known as egcs-1.1.2), then just download the source RPM and have rpm do the rebuild for you as follows: $ rpm --rebuild root-gcc-c++-2.95.2-3.00.06-1.src.rpm If you want OpenGL support compiled into your ROOT, then you should download and install the Mesa RPMS as well (available at the same location where you downloaded the ROOT RPMS). 5) You can have multiple installations of the same version of ROOT, as well as multiple installations of different versions of ROOT, installed on the same machine. Just do an rpm install (e.g. use the "-i" flag) instead of an rpm upgrade (e.g. the "-U" flag). This functionality allows you to test out a newer version of ROOT while still keeping an older version around, as well as allowing you to use multiple (and often times incompatible) C++ compilers. -- Matthew D.
