RPMS of ROOT 2.24.02 (released 2000.04.07) are available for RedHat
Linux 6.1 Intel at ftp://ftp.slac.stanford.edu/users/langston/root/.

The two RPMS that you will want to download were built with the newer
g++ from gcc 2.95.2:

     root-gcc-c++-2.95.2-2.24.02-1.i386.rpm
     root-gcc-c++-2.95.2-examples-2.24.02-1.i386.rpm

NOTES:

  1) There is a buglet in ROOT 2.24.02 which causes the following
     message to appear when you start ROOT:

       Note: posix.dll is not found. Do 'sh setup' in $CINTSYSDIR/lib/posix directory if you use UNIX.

     We are told by the ROOT developers that this message can be safely
     ignored, and that the source of the problem will be fixed in a
     later release of ROOT.

  2) The ROOT splash screen displays the wrong version number, as it
     still says "Version: 2.23".  Rest assured that these RPMS really
     are ROOT 2.24.02.  The ROOT text welcome message does display the
     correct version number.


  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++-2.95.2-2.24.02-1.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.
